In A Dehydration Reaction Essay, Research Paper Time as a Determinate of Final Product in a Dehydration Chemical reaction Robert Simack, Department of Chemistry and Biochemistry, University of Alaska Fairbanks, Fairbanks, Alaska. Abstraction: This survey involved acerb desiccation of 2-methylcyclohexanol. The consequences varied depending on the clip elapsed after initial reaction. I attempted to turn out the Evelyn Effect, which stated that over a period of clip the merchandises of the aforesaid reaction will beobserved to alter volume so that those merchandises formed by a cis isomer of 2-methylcyclohexanol will organize foremost. However, one time all molecules in the Commonwealth of Independent States isomer undergo reaction the staying trans configured 2-methylcyclohexanols will proliferate during the latter period of the reaction. I besides postulated as to the possible preparation of 1-ethylcyclopentene, and to the cause of such an event. Introduction: After researching acid-catalyzed desiccation reactions ( McMurray ) and background on the Evelyn Effect ( Clausen ) I hypothesize that the cis isomer of 2-methylcyclohexanol will respond via an E1 type procedure organizing 1-methylcyclohexene harmonizing to anticipations from Zaitzev? s regulation ( Lehman ) . We will write a custom essay sample on Time As A Determinate Of Final Product or any similar topic specifically for you Do Not WasteYour Time HIRE WRITER Only 13.90 / page This should be due to the fact that the Commonwealth of Independent States isomer has 2 anti-coplanar Hs. These two Hs should do the molecule more reactive. The trans isomer, with merely one anti-coplanar H, should be slower to respond and will organize a 3-methylcyclohexene. In add-on the 1-ethylcyclopentene will be formed from both the Commonwealth of Independent States and trans isomers but merely if the hydroxyl group is in an equatorial place. In that place negatrons from the ring may assail the intoxicant straight from behind forcing it off the ring and organizing a 5-membered ring alternatively. Results A ; Discussion: An NMR ( 300MHz ) spectra of the original reagent and the three fractions provided a immense sum of information in support of my hypothesis. Both Commonwealth of Independent States and trans isomers were present in the spectra for the original stuff every bit good as for the first two fractions. The intoxicant? s H showed up at about 3.79 and 3.1 for Commonwealth of Independent States and trans severally. In the spectra for pure get downing stuff ( ref: Jim Starr /Steve Standish NMR 24 March, 2000 ) Commonwealth of Independent States isomers of get downing stuff comprised merely 25 % of the sample compared to 75 % of trans as observed in the integrating of extremums. In the spectra for fraction one a 3:1 ratio of trans to cis was observed. In the spectra of fraction two the Commonwealth of Independent States isomer about disappeared ; the ratio was approximately 6:1 trans/cis. Finally, in the spectra of the 3rd fraction the Commonwealth of Independent States isomer was perfectly unperceivable while the integrating of trans was about twice that of the integrating from fraction one. These spectra show that Commonwealth of Independent States reacted first and was rapidly consumed by the reaction go forthing trans isomers to complete the reaction. Because it is kn ain that the reaction with cis get downing stuff caused both 3-methylcyclohexene and 1-methylcyclohexene I postulated that the first merchandise of the latter phases of the reaction must be 3-methylcyclohexene, which is the exclusive merchandise of the trans reaction ( McMurray, fellow. 11.12 ) . In add-on to the Commonwealth of Independent States and trans peaks the extremum for both 3-methylcyclohexene and 1-methylcyclohexene could be found on the spectra at 5.7 and 5.4 severally. The NMR showed that the integrating of 1-methylcyclohexene dropped merely somewhat throughout the reaction while the integrating of 3-methylcyclohexene increased about tenfold. The findings from the spectra prove the hypothesis that the Commonwealth of Independent States reaction will travel the fastest followed by the trans because as the Commonwealth of Independent States is consumed it? s extremum at 3.79 will diminish every bit good as the extremum for 1-methylcyclohexene due to expiration of that mer chandises formation. Besides, extremums for 1-ethylcyclopentene Begin to demo in the spectra for the 2nd fraction and increase in size ( country beneath the extremum ) by the spectra of the 3rd fraction. At the root of this phenomena is steric hindrance. Both the Commonwealth of Independent States and trans isomers will organize 1-ethylcyclopentene ( fig. 1 ) . However, because of steric hindrance the trans isomer is favored to organize the 1-ethylcyclopentene. This fact will explicate why more of the pentene shows up in the 3rd fraction. Finally, a bantam extremum showed at 4.6 in every fraction? s spectra bespeaking the presence of methylenecyclohexane. This merchandise formed from the original merchandise by acerb accelerator. Experimental: An setup was constructed with a unit of ammunition underside flask topped by a claisen adapter in which was placed a thermometer and a condensation tubing. In the setup 150mmole of 2-methylcyclohexanol was assorted with 5mL H3PO4 and distilled. The distilled liquid was collected in three tubings, at about 4mL per tubing, labeled fraction 1, 2 and 3. Each fraction was placed in a extractor tubing and combined with 4mL concentrated NaHCO3. The aqueous bed was removed and MgSO4 was added for a concluding separation. The solid and aqueous beds were so removed and the concluding merchandise was combined with CDCL3 in an NMR tubing in readying for spectra. The liquid staying in the original setup was put through the separation procedure described above. However, alternatively of CDCL3 as a spectrum reagent we used CH2CL2. Besides, an NMR was non performed on the staying liquid but alternatively a GC.

Some barriers to trade were removed immediately, while others were removed over a period of time. NAFTA addresses textile and apparel, transportation, energy, intellectual property, investment and more. After the creation of NAFTA, two additional related agreements were created to address labor and environmental issues. Prior to NAFTA, U.S. exports to Mexico were in a decline. After NAFTA was introduced, that trend was reversed and 72% of the agricultural products imported into Mexico in 2007 were from the U.S. This agreement has negatively impacted local Mexican labor leading to higher levels of workers remittances. It has also negatively impacted the agricultural sector of Mexico leading to higher levels of workers remittances after workers migrate to America. Finally, it has increased the number of farmers who migrate for long periods of time away from families in search of illegal jobs in America leading to higher levels of workers remittances. Due to NAFTA Mexico has made strides in nearing the levels of exports of the United States and Canada. Mexican imports to the U.S. have increased four times since the implementation of NAFTA, rising from $60 billion per year to $280 billion. In addition, Mexico has moved from a closed economy becoming open to investments and foreign markets. The amount of foreign direct investment in Mexico has also increased from $1.3 million prior to the implementation of NAFTA to $14 billion after the agreement was launched. Mexico has faced challenges as a result of NAFTA. For instance, the creation of the free trade agreement has not raised the standards of living nor has it created increased incentives for Mexican workers to remain in Mexico instead of migrating north and sending workers remittances. In addition, the agricultural sector in Mexico has suffered. The Mexican agricultural sector had been highly segmented and contained a large number of small and medium size farmers. It simply was not ready to bear the deregulation of the market as a result of NAFTA. In spite of initial promises by the government to impose tariffs that would ensure a more gradual transition, those promises were never implemented. Instead the market was opened up to imported farm and food products from the U.S. The effect was severe for small and medium size Mexican farmers, who found it difficult to compete with U.S. producers that were large and substantially subsidized. U.S. farms tend to be much larger in terms of crops and acreage and are often heavily subsidized. Consequently, products can be sold at prices that are much lower in Mexico as compared to locally grown products, particularly maize or corn. In America agriculture is primarily concentrated on a large number of farms in rural areas that are huge and specialized. Less than one-quarter of the population in the United States now lives there. These farms, which are highly mechanized and productive, employ only a small percentage of U.S. workers. In place of the work animals that were once used, some 5 million tractors are now utilized. As a direct result of this transformation, agriculture in the United States has become very efficient and able to contribute to the overall growth of the economy in the U.S. Output from farms in the U.S. has increased dramatically, making it possible for consumers to spend a much smaller percentage of their income on food. In addition, a large percentage of t he population has been freed to enter non-agricultural occupations that support economic growth and development. This transformation has been spurred by innovation in technology along with changing market conditions.   As a result, production agriculture has become a much smaller player in both national as well as local rural economies. Although an increasingly integrated market structure has been established in order to meet safety and quality demands from American consumers, global markets have also introduced new consumers at the same time as well as new competitors. This has led to workers illegally crossing the border into America in search of jobs, and using workers remittances to help their families back home. Overall, NAFTA has proven detrimental to the agricultural sector of Mexico which simply cannot keep in pace with American production. This has led to workers moving to America in search of jobs, both legally and illegally, which has impacted the rate of workers remittances. Moving where there is work, many farmers from Mexico leave their families for extended periods of time in order to send back as much money as possible.

6 Proven Ways for Women to Get a Higher Salary

6 Proven Ways for Women to Get a Higher Salary By now, you’ve likely heard the rather grim statistics: on average, women earn less money than men for comparable jobs. In 2015, women made 80 cents for every dollar earned by men in the same roles, according to the Institute of Women’s Policy Research. The whys and hows of this salary difference is kind of a political football- everyone seems to have an opinion why that is, or even whether the gender gap truly exists. While that discussion is for another time and place, let’s go with the stats on this one, and look at how women can overcome challenges and pay disparities to improve their own salary outlook. 1. Be your own best advocate.The first thing you need to do is understand that this is your ball to carry. No one is going to come along with a big check and say, â€Å"You know what, you deserve more money. Take this!† No matter how awesome you are at your job, or how above and beyond you’ve gone lately, it’s most likely going to be up t o you to help ensure that you’re being compensated as much as possible.This is something I’ve struggled with personally throughout my career. I’ve always had the mindset of, â€Å"I’m gonna work really hard, and be really great at this, and people are going to notice and reward me accordingly.† Guess what? Praise and acknowledgment don’t necessarily translate into higher salary. Once I realized that it was on me to make sure I was making what I was worth- and taking positive, proactive steps to make that happen.2. Know your market value.This is key. Increasing your salary is going to be very difficult if you don’t really know what other people are making in your field and at your experience level. If your ask isn’t reasonable, your chances of getting a bumped-up salary are somewhere in the area of â€Å"laughed out of the room.†In another hard lesson in my career, a colleague who was leaving our company let me know what he was earning there (we had the same job title and responsibilities). It was significantly more than I was making at the time, and I was floored. When I brought this up to my boss, her response? â€Å"You weren’t supposed to know that.† Maybe not, in some unspoken â€Å"talking money is rude† kind of way, but I did know it, and it gave me a number to aim for when it came time for the annual review and salary increase.You shouldn’t have to rely on the grapevine to know what others are making, but you also probably shouldn’t walk right up to your coworkers and demand to see their pay stubs. We have tons of great tools available to us to find out what others are making in our industry, and what we can reasonably expect based on experience, location, etc.:Salary.comPayScaleGlassdoorYou can use all of these without having a single awkward conversation about salary and personal finances. Don’t hesitate to have as much information at your disposal as possible. And don’t let anyone convince you that it’s rude to talk numbers when it comes to your own career and salary goals.4. Negotiate every time.According to Stanford-based leadership expert Margaret A. Neale, women just don’t negotiate at the rates that men do. And in fact, Linda Babcock, author of Women Don’t Ask, found that while 57% of men negotiate salary, only about 7% of women do. Seriously, 7%! It looks like everyone- men and women alike- should be negotiating more, but especially women. Not negotiating is like closing a door without checking to see if anyone’s there. How do you know if there’s an opportunity to increase your salary if you haven’t even tried yet?And don’t think that negotiation is just for new job offers- you should be negotiating your salary at every chance, including annual reviews, after times when you’ve gone above and beyond at work or taken on new responsibilities successfully, and/ or when you discover that your market value is higher than your current salary level. Whether you’re a negotiation newbie or want to bump up your skills and become a master negotiator, we have plenty of resources for you:Your Comprehensive Guide to Negotiating SalaryHow to Get a Raise at Work6 Tips for Negotiating the Salary You WantThe Super Easy Guide: How to Negotiate a Raise and PromotionThere are also lots of experts online who have honed their negotiating skills, and want to share that information with other women. Resources like MichelleMotivateMe are a great place to start:Once you get over any hesitations about getting in there and playing the negotiation game, you’ll have started advocating for yourself and your salary goals in the best and most direct way possible.5. Think small (company).If you’ve tried negotiating and still fallen short of your salary goals, it might be time to think about switching companies. Hired.com investigated wage gaps at dif ferent kinds of companies, and came up with some intriguing statistics around the unfortunately traditional wage gap. It turns out that smaller companies and startup companies are less likely to have significant wage gaps, compared to companies that were bigger and more corporate, or that had been established longer.The thinking behind this? Small companies tend to have more visibility into salaries, which is an equalizer. If employees know that Frank two desks away is making more for the same job, the company has an employee relations incentive to keep things more equal. The other interesting angle was that startup (or â€Å"seed stage†) companies may have less pay disparity because they have less flexibility in the salaries they can offer employees, so they can’t really afford to offer one employee a drastically different salary than another employee in the same role.So what does this mean for your own salary? You might want to consider whether there are companies in your field that can offer you better salary- less established companies that you may not have considered before.6. Think outside your career box.If you feel like you’re stuck in a pay rut, you might also want to consider a job change. There are growing fields, like logistics/trucking, manufacturing, and information technology, where women are the minority of workers. Many women have the base skills necessary for these â€Å"middle-skill† jobs (which often don’t require a college degree), but just aren’t pursuing them at the same rate men are. If you’re looking for more opportunities to segue into higher-paying roles, one of these industries might be a great path for you. (Just don’t forget to negotiate!)The good news is that statistics may inform us about what’s going on, but they don’t have to define us- or our careers. There’s no reason to accept the status quo when it comes to your own career and your goals. If youâ €™re a woman and you’re interested in boosting your earning potential, you have tools to help you do that. And if more women take control of their salary destiny and start using all of those tools, we can start changing those stats, one closed gap at a time.

A two year old child in extended family Essay Example | Topics and Well Written Essays - 1500 words

A two year old child in extended family - Essay Example Observations of my case study family led me to understand that the meaning of family is an idea that is enacted through a core, stable group of people that is extended through a fluctuating series of others who come in and out of the home. Henry (1996, p. 32) writes that parents can meet the needs of children through mechanisms of secure attachment, but interactions with others through additional secure attachments can actually enhance childhood attachments with parents. Part of the socialization of a child is to create interactions with a variety of people and to help them engage the world (Edgar 1995, p. 5). As much as the intention of observing is to be on the outside of the family, I found that in my experience the intentions of a toddler will override the intentions of the observer and include them in the family process. The study of the family is the study of origins. Studying different families means studying their diverse cultures to see how differences have an influence, if any, on how children develop (Shimoni and Baxter 2008, p. 47). The family that I visited was Muslim and the structure of the family was nuclear with a mother, father, and extended family consisting of the paternal grandmother and grandfather with whom the parents and the child lived. The mother was focused on the activities of the child with the father being unable to be as focused on the development of the child as he was preoccupied with work for most of the time I observed. (Edgar 1995, p. 5).  ... The study of the family is the study of origins.

The mother was focused on the activities of the child with the father being unable to be as focused on the development of the child as he was preoccupied with work for most of the time I observed. The motherhood ideology has mothers at the centre of reproduction and early childhood interaction (Reiger 1995, p. 48). The grandparents were very involved in the experiences of the child with an almost equal participation. Shimoni and Baxter (2008, p. 48) discuss a study by Wearing who determined that the ideology of motherhood still held that there is a â€Å"legitimate men’s social power and maintain women’s primary responsibility for child-rearing†. The study also determined that women feel that a ‘good’ mother was always available for her children and being a woman and being a good mother were an intermeshed identity. In studying my case study family I found that this framework of motherhood held true. Observing and Interacting One of the problems with observing is maintaining a barrier between the observer and the observed. During the course of my observations I became close with the family as the mother confided in me some of her concerns and the child interacted with me during the course of the observations. Beckett (1988, p. 140) discusses the nature of the

Explanation of Security Breach and Request for Formal Apology Essay

Explanation of Security Breach and Request for Formal Apology - Essay Example A month ago, the lock manufacturer sent me an email to warn me of the possibility that the lock could malfunction and to schedule for a technician to come and fix the lock’s firmware. No further queries were made on this issue following the current measures on cost-cutting, and the fact that the Head of Security was dismissed six weeks ago. I apologize for not informing you of the problem with the system on time. I am heavily involved in planning for the launch of the Bionic Leg event, a project that is critical to the company’s ongoing success, and that is why I have not had time to resolve the issue. Linda is an important employee to our company because she is the most knowledgeable person in Canada in the field of bionics. Bob Loblaw is the only other person in the company who possesses similar expertise. Since they work together, there is a chance that if Linda were to leave then Bob would also leave. This would be a great loss for the company. Without the service o f these two key employees, the Bionics Division would be forced to close. In the last three years, the company has been surviving on the revenues generated from the Bionics Division. Furthermore, we risk losing Linda to our main competitor, Bionic Works Co., which has been trying to poach her from us for quite some time. Her decision to stay is based on her loyalty to my leadership and because she enjoys working with our team. To prevent Linda from leaving the company, we need to compromise company policy and fulfill her terms.

Mike F. Doyle House Representative of PE :: essays research papers

Michael F. Doyle is a House Representative in Pennsylvania. Doyle represents the 14 district which includes the city of Pittsburg and most of Allegheny County. Doyle is now serving his fifth term in congress. Doyle’s top priority is to create jobs, preserve social security and Medicare, provide better public education, meet the needs of senior citizens, establish long-term energy strategy, and to promote a better climate for the high-tech community. Doyle was born on august 5, 1953 in Pittsburg PA. Mike Doyle has a wife, Susan Doyle and 4 children, whose ages are 18, 14, 12, and 5. Doyle was first elected to office November 8, 1994 to the Democratic party. The last time Doyle was elected was November 2, 2004. Doyle went to B.S. Community Development and Penn State University, where he received a Bachelor of Science degree in Community Development in 1975. Doyle is licensed in life, accident, health, property, and casualty insurance. In July, 2004 Doyle had called for a legislation to prevent massive power blackouts like the one that hit the northeast this past year. In August 14, 2003, a massive power outage affected more than 50 million people in eight different stats, Ontario, and Quebec in Canada. Many households were without power for several days. This blackout began in Ohio, where three transmission lines short-circuited. An investigation found that the energy company that owned those power lines was in violation of at least four North Electric Reliability Council operating standards. Doyle introduced almost a year ago a legislation that would establish a national Electric Reliability Organization to enforce power reliability standards across the country. If an organization was to be established it Amer Gov/Easter  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚   Chris Zane Mike F.

Doyle’s plan was named H.R. 3004 and was introduced on September 23, 2003. Unfortunately, H.R. 3004 has been stalled for months, and the House leadership has suddenly refused to consider it. In October, 2004 Doyle announced that he is working to promise that Congress passes a legislation to improve the supply of flu vaccine before the supply runs out later this year. Doyle has asked that he be added as a cosponsor of the Flu Protection Act. The legislation would offer tax credit for the expansion of flu vaccine production facilities, and would offer a government buy-back guarantee for the vaccine makers who end up with extra flu vaccine doses at the end of the flu season.

Mouldy Bread

I. Abstract This experiment was run to see how fast molds grow on bread in 3 different dry location, such as indoor room, fridge and freezer. The samples in a plastic container at room temperature showed mold in fewer days than the samples that kept in low temperature place as fridge and freezer. I think that this is because it was a better environment for the molds to grow. The breads that is kept cool will last longer on the plate than bread in normal room temperature. II. Introduction The purpose of the experiment was to know in what conditions the mold most grow and how fast.I thought that this would help people to find the best place to store the bread so that it would stay fresh and last longer. I also was curious about which factors do most affect the mold’s growth. I learned from my food science subject that mold is a tiny spores in the air that fall into damp food especially bread and grow by producing chemicals that root down the food, which also causes a bad taste f or the food. If you look under a high power compound light microscope, you can see these microscopic look like threads that seem to be spread out thickly on the bread.Bread mold is found in many different types, shapes and colours. The most common bread molds are Penicillium and Aspergillus family. Penicillium and Aspergillus molds usually appear to be similar with spherical shape, also green and grey in colour, but both are different. Aspergillus mold have fine hairs that contain large balloons with spores inside. Some molds cause allergic reactions and respiratory problems. And a few molds such as Aspergillus produce mycotoxins, poisonous substances that can make us sick.The molds can be controlled by many different factors, such as the temperature, Ph (acidity and bases range), and the moisture. The optimum temperature for molds growth is around 20 – 35 oC and terminated at 100oC. The Ph range for growth is around 2 (acid) to 8. 5 (base), which means that it is extremely h ard to control its acidity. They also need moist ground to grow on the surface, but it depends on how much free water particles inside which will changed into solid when the temperature reach 0o C. I have oticed that food left on the counter in the summer molds faster than food left out in the winter, this is the proof that mold likes warm environment. I also found out that the mold grows on the bread even in the dry place, which means that mold just need a very low moisture. My hypothesis is that the bread inside room temperature will grow faster than other samples that inside the refrigerator, because the amount of free water molecules will be decreased or even become solid. III. Materials * 3 slice of Wonder Whole Meal ( White loaf bread ) * 2 Plastic plates 1 Plastic container * 1 Fridge * 1 Freezer * 1 Eye dropper * Water IV. Methods 1. Take out the bread of the package 2. Place one piece on each plastic plates and plastic container 3. Labeled the plastic plates ( B and C ) and the plastic container (A) 4. Take 30 ml amount of water into the eye dropper 5. Drop every 5 drops into each samples, once a day 6. Seal the plastic container 7. Place the plastic container on the counter 8. Put the other plates inside the fridge and freezer 9. Check back every plates every days for a weeks ( around 10. 00 PM ) 10.Record the data by measure the amount of mold by percentage (%) covered on each pieces of bread. V. Results Over a week and 7 days studies, I saw a slight difference in the amount of mold that grew on every pieces of bread. The bread in the plastic container grew much more than the other samples; even I can barely see the differences between the bread inside the fridge and the freezer. I measured the percent covered by mold on the top side of the bread. Data on % coverage can be seen below. The chart can be seen below in figure 1. Day 1, A=0% B=0% C=0%In the first day, I prepared all the materials and put them on the counter, fridge and freezer. Day 2, A= 0% B=0% C=0% In the second day, I don’t see any difference on the breads either. In this step I believe that it still need more time before the result comes up. Samples B and C become fragile. Day 3, A=4% B=0% C=0% In the third day, the sample A start to show the mold activities, it covered a small area around the corner of the side and start to shrink a little. But there is no difference on the others samples. The samples B accidently cracked because I put something on it. Day 4, A=11% B=0% C=0%In the fourth day, the molds on the sample A keep spreading around the surface, its colour is dark green and produce some bad smell, while the other samples still clean. Day 5, A= 15% B=0% C=0% In the fifth day, I saw a little difference in the mold’s area size but the bread really shrinks, the others two stay the same. In this day I try to not put some water into the samples. Day 6, A=15% B=0% C=0% In the sixth day, I can’t see any difference on all the samples which I came up with a conclusion that the mold really needs water to keep grow in the dry situation like Melbourne. Day 7, A=20% B=0% C=0%In the seventh day, the last day of my study, I found out that the threads of mold keep spreading around the top side o the bread and have a lot more verity of color, such as navy green, dark green and black. In contrast, the other 2 samples showed us that there is no single activity of mold appears but in exchange the bread become so hard and fragile. Figure 1. Percentage of mold coverage on bread VI. Discussion The mold grew a lot more on the bread in the container which stay at the room temperature and there are not even a single mold on the breads that stored inside the fridge and freezer.I think this is because the free water molecules inside become solid in a day and cause the mold growth to stop. In the seventh day the mold was starting to show a lot of different color. There was pale green, dark green and black color showing up at the end. I thi nk if it kept going, the whole piece would be covered in a month. The bread that stays at room temperature is out of my expectation, because it should be mold faster than this. I believe it was caused by the cold temperature these days, as we entering the winter season. It kept the mold from grows as the free water molecules decreased.If the bread that you buy is moist and you keep it inside the plastic bags it will mold. So to prevent it from molding you can store it inside the refrigerator, either fridge or freezer is okay. It is still unclear from this experiment about how to slow down the growth of mold other than froze the bread. The frozen bread as the result of stored it inside the fridge will make lose its softness and it was getting as hard as the pores got dry. It can’t return to its original characteristic anymore. The other way is to dry toast it; it won’t mold more than a week since the progress is the same as the refrigerator.It didn’t look like it could let any more molds to grow. Also, the rate of coverage stopped increasing on the dry bread, so it might be done. VII. Conclusion Mold grows better in a moist environment than it does in a dry environment. The plastic container kept the moisture in and allowed the bread to mold. The temperature is also taking a big part in this experiment which means the lower the temperature, the longer it will stay edible. It seems to be sure that fridge and freezer is one of the best solution to kept the bread stay last longer. VIII.
