The paper is done, but I need to edit it based on comments from my TA. She said at the moment, this would give me 92/100. Here are the comments: "Although you clearly articulated your proposed solution, I would have liked to see more evidence-based data to support your claim. Additionally, smoking products already have labels." Also, for the highlighted sentences, they need to be cited correctly.

Topics (select one) a) Stem cells. Your friend has suffered a spinal cord injury after a bad car accident. The medical team has decided that he is a good candidate for a clinical trial using stem cell therapy. Your friend has not had a biology course since high school, so you decide to write him a letter sharing your knowledge of stem cells. Include in your letter a description of the biology of stem cells and how these cells are unique from other cells. Contrast the different types of stem cells, including pros and cons for each type. Explain how stems cells can be used to treat diseases and injury, with special focus on spinal cord injuries. Include information from at least one research study or clinical trial. Conclude with your own opinion. b) Genetically modified organisms (GMOs). A friend tells you that she avoids foods containing GMOs because they are unhealthy. You decide to use the knowledge gained from your biology class and some additional research to form your own opinion on GMOs. Answer the following questions backed up by reliable information sources. What is the purpose of genetically engineering of crop plants? Include at least two specific examples of commonly grown GMO crops. How are GMOs created? Use the provided course materials and make a connection to the central dogma of molecular biology in your explanation. Which foods in your supermarket contain GMOs? Are foods that contain GMOs safe for human consumption? What types of regulations exist for these foods? Clearly explain your reasoning for each answer in your paper and conclude whether or not you agree with your friend. c) Clustered Regularly Interspaced Short Palindromic Repeats (CRISPR) has been the most recent breakthrough discovery in bioengineering that enables scientists to edit DNA. Because you have studied biology in this course, you have volunteered at your niece’s Middle School Science Club to monitor a student debate about CRISPR. The students will be watching the following video before the discussion:https://www.com/watch?time_continue=252&v=2pp17E4E-O8and you need to be prepared in case there are any questions. Please research and write an answer to each of the following questions: What is “CRISPR”? What role does Cas9 play in the CRISPR process? How does the CRISPR-Cas9 system snip and replace any DNA sequence? What are the potential benefits and drawbacks of gene editing? Include specific examples. Do you believe that the inherent risks of modifying animal DNA is worth the rewards? Explain. Do you believe that it is ethical to genetically engineer humans and/or animals? Explain. d) Vaccines. Your friend is worried about the many vaccines that his newborn son is scheduled to receive and asks you for advice since you are taking a biology course. Start with an explanation of how vaccines work. Briefly contrast the traditional methods used to create vaccines with more recently used biotechnology techniques. Then list some of the diseases that babies and children in the US are routinely vaccinated against. How has vaccinations impacted the frequency of these diseases over the past 100 years? Why are some people worried about giving their children vaccines? Is there scientific evidence to support these concerns? Conclude with advice to your friend in regard to getting the recommended vaccines based on what you learned from reliable information sources. e) Fracking (hydraulic fracturing) and tar sands (oil sands). With society's dependence on nonrenewable fossil fuels, the oil & gas industry is turning to hydraulic fracturing and tar (oil) sands to extract natural gas and oil. A friend asks you "What's all this controversy in the news about fracking and tar sands?" Briefly explain to your friend how hydraulic fracturing and tar (oil) sands are used to obtain these fossil fuels. Then, in more detail, describe the environmental problems that may result from these processes and why they are controversial. Issues that should be addressed involves water, air and soil pollution with special focus on global climate change, effects on human health, and effects on other species and natural ecosystems. Finally, give your opinions on possible solutions to these environmental problems, with your reasoning backed by information from reliable information sources.

True Fact: The Lack of Pirates Is Causing Global Warming By Erika Anderson, Forbes Magazine March 23, 3012 It’s true. This extremely scientific graph proves it: You can see that as the number of pirates in the world has decreased over the past 130 years, global warming has gotten steadily worse. In fact, this makes it entirely clear that if you truly want to stop global warming, the most impactful thing to do is — become a pirate. Hope you’re laughing. My husband told me this wonderful premise a few months ago, and I couldn’t resist sharing it with you, for a very specific reason. I’m fascinated by why it’s so funny. I believe it’s because it’s an only slightly more extreme version of the fake logic we hear every day — the conclusions that pass for critical thinking in these days of completely unleashed 24-7 communication. For example: Someone who has cancer drinks gallons of lemon water and their cancer goes into remission: they create a website to talk about how lemon water cures cancer. A business is doing badly and they move to a new building and things start to pick up: the CEO writes a book about how changing your environment is the key to success. Statistics show that people who leave their jobs after less than a year are more likely to smoke: someone starts a campaign to reduce smoking by encouraging people to stay at their jobs longer. My older sister, a very wise and smart woman who is a political scientist at Syracuse University, teaches a statistics class to freshmen, where she endeavors to teach them critical thinking. She talks about this as being the most common error in logic: confusing simultaneity with causality. In other words, assuming that because two things are happening at the same time, they exist in a cause and effect relationship with each other. Because anyone can say anything anywhere these days (pretty much), there’s a lot of fuzzy thinking floating around that seems more legitimate than it would have in former times because it’s in print. Now, don’t get me wrong: I’m a huge proponent of free speech. I just feel we all have to be more discriminating than ever before about what we believe. Not cynical or negative: discriminating. So, when someone proposes a cause and effect relationship between two things – reduction in pirates causing global warming; Obama creating the global economic crisis; young people ruining American business – ask for the data that shows they’re related, rather than simply that they’re happening at the same time. But if you’re dead set on becoming a pirate, I’m not going to stop you. Questions Does the lack of pirates cause global warming? Why or why not? What is the difference between causation and correlation? Use your phone or computer (or collaborate with neighbors) to define each and discuss the differences between the two. Why do people often confuse correlation and causation? If you want to show that something causes something else, what do you have to do? Why? It's three assignment and their discussion

BacterialGrowthin LiquidMedia LEARNING OBJECTIVES Overall: Examine growth of bacteria in liquid broth both qualitative and quantitatively Detailed: 1. Understand how turbidity measurements can be correlated to growth of bacteria. 2. Draw a bacterial growth curve and describe what is happening in the cells in each phase. 3. Calculate generation time 4. Predict the effect of different growth conditions on a growth curve 5. Predict expected results of an experiment that studies bacterial growth. 6. Analyze the results of a simple experiment that studies bacterial growth. BACKGROUND Bacteria multiply by the process of binary fission. Binary Fission is a type of cell division wherein number of cells are doubled after each division (1-> 2-> 4->8->16->32.....). The time it takes for a population to double in number is called the generation time. This time varies among different species and is influenced by the conditions in which the cells are grown, such as temperature, oxygen, and acidity. Each species of bacterium has an optimum for its growth conditions. Growth depends upon several environmental factors surrounding the bacteria such as pH, temperature, oxygen content and presence of nutrients in the medium. When the supply of nutrients is limiting, bacteria will deplete the nutrients in their environment and produce waste products which will eventually inhibit their growth Bacterial growth can be followed by determining the number of bacteria in a sample over a period of time. An increase in the number of bacteria over time indicates growth. Two common methods used to determine growth are (i) standard plate count, and (ii) measurement of absorbance. In the standard plate count method, a dilute bacterial sample is spread on an agar plate and the number of colonies that are formed are counted after 24-48 hours of incubation. This method assumes that a single bacterium will divide to produce a colony on the plate. Therefore, the number of colonies multiplied by the dilution factor (in cases where the sample is diluted before plating) will give the number of bacteria in the sample. The counts determined by the standard plate count is reported as colony forming units (CFU). This method counts only viable cells (live cells capable of forming colonies). The second method follows the growth of bacterial cells by measuring turbidity or cloudiness of the liquid culture. Turbidity of a culture increases as cells divide and increase in numbers. Turbidity is measured using a spectrophotometer. FIG 1 shows culture tubes containing increasing bacterial concentration (number of bacterial per mL of broth). As number of cells increase (from tube left to right), the culture becomes more turbid. This is an indirect
