Select one of the topics listed below.2. Find at least two information sources related to the topic. You can find assistance with searching for articles at the athttp://libguides.umuc.edu/science.3. Write a 750-1500 word paper, excluding references and title page. You must read the information sources that you find and summarize the information in your own words, addressing each of the questions and expectations for your chosen topic. Extensive quotes from the article are discouraged. Use APA style for citing references, seehttp://www.umuc.edu/library/guides/apa.html.4. Post your assignment to your Assignments folder by the due date listed in the course schedule. Topics (select one)a)     Genetically modified organisms (GMOs). What is the purpose genetic engineering of crop plants and domestic animals? Briefly explain how GMOs are created. What foods in your supermarket contain GMOs? Are foods thatcontain GMOs safe for human consumption? What types of regulations exist for these foods? Clearly explain yourreasoning for each answer. The following website from FDA regarding GMO regulation may be helpful:http://www.fda.gov/ForConsumers/ConsumerUpdates/ucm352067.htmb)    Stem cells. Your friend had 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 ofthe biology of stem cells and how these cells are unique from other cells. Contrast the different types of stem cells,including pros and cons of each. Explain how stems cells are can be used to treat diseases and injury, with special focus on spinal cord injuries. Conclude with your own opinion. The following website from NIH regarding stem cell research will be very helpful: http://stemcells.nih.gov/index.asp.c)     Fracking (hydraulic fracturing) and tar sands (oil sands).  With society’s dependence on nonrenewable fossil fuels, the oil & gas industry is turning to the use of hydraulic fracturing and tar (oil) sands to extract natural gas andoil respectively.  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 moredetail, describe the environmental problems that may result from these processes and why they are controversial. Issues that may be addressed involves, but are not limited to, water, air and soil pollution, effects on human health, effects on other species and natural ecosystems. Finally, give your opinions on possible solutions to these environmental problems, with your reasoning backed by the references that you studied. The following websites from EPA may be helpful: http://www2.epa.gov/hydraulicfracturing

What are the nearest relatives of your chosen species?

/in /by

Question 1

Select one species of organism that is interesting to you (try to pick something different from your classmates’ choices—you only have about two million to choose from). Show the hierarchy of classification for the organism you choose from Domain through to binomial name (genus and species). Be sure to write the names in correct format and to spell correctly.

What are the nearest relatives of your chosen species? How do the levels of classification for your species trace the major evolutionary steps the ancestors of your species took over time? Be prepared to discuss similarities and differences in the evolution of diversity in the examples chosen by your classmates.

Question2

Innovation and Diversity

Over the long period of time that life has existed on Earth, there have been a number of important or significant innovations including (but not limited to) endosymbiosis to create mitochondria and chloroplasts; multicellularity; adaptation to land by plants and animals; development of exoskeletons in arthropods, shells in molluscs, and notochords followed by vertebral columns in chordates and vertebrates; and bipedalism in the ancestry of humans. All of these had to come about by natural selection in response to changing environmental forces.

Pick one of these significant innovations and describe:

  1. How the innovation appears to have happened
  2. What environmental challenges were met and overcome by this innovation, and
  3. What opportunities were opened for the organism that made this innovation.

Be prepared to discuss the general concept of innovation and opportunity in response to selective challenges in life and how this can greatly increase biodiversity over time.

Different genes have been found to evolve at different rates.

/in /by

Geneticists compare DNA base sequences among organisms and from this data determine a gene’s rate of evolution. Different genes have been found to evolve at different rates. Explain why some genes might have faster rates of evolution than other genes as populations adapt to their environments, and give an example with your explanation.

Pedigree Analysis Assignment

/in /by

Pedigree Analysis Assignment

For this assignment you will need to pick a heritable trait in your (or your friend or relative’s if you have limited information about your biological family) family and build a pedigree consisted of three generations and at least 10 individuals.

Next to each square or circle on the pedigree, please write the name (feel free to use fictitious names to protect privacy) of the individual and possible genotype(s) this person may have for the trait being studied. Make sure you define which “letters” are used to represent which alleles. If someone is missing on your pedigree, represent them with a question mark and note if they had to have been affected or a carrier or if it is unknown.

The DNA Learning Center has a great tutorial on how to make a pedigree! Use the link here (Links to an external site.) to visit their site before you start.

Which trait should you look at? To be able to easily follow and predict inheritance patterns, it is best to pick a trait that is not polygenic. But most human traits are.

If there is a known genetic disease in your family, this is a perfect chance for you to do some further investigation. Some human disorders controlled by a single gene are cystic fibrosis, phenylketonuria, sickle-cell disease, Tay Sachs disease, Achondroplasia, Huntington’s disease, Marfan syndrome, and hypercholesterolemia. Note that some of the disorders mentioned are dominant, and some are recessive.

Everyone in the family is healthy? Or family members suffer from diseases with multifactorial causes such as heart disease and diabetes? Then use this link to learn more about 10 observable human characteristics. Although the website suggests most of these characteristics (all except freckles, red/green colorblindness, and PTC tasting) may be polygenic or have environmental factors, you can treat them as monogenic and see if you see deviations from expected phenotypes within your family pedigree. This site also has pictures for your reference. You probably will not be able to do PTC tasting at home, but the other 9 are easily observable. You can also look at the “ear wax’” trait mentioned by Hank and his brother in the Crash Course video.

What is Due:

  1. The pedigree (like the example above) with names and possible genotypes for most, if not all, individuals in the pedigree
  2. Definition of “letters” used to represent alleles.
  3. A brief written description of what trait you chose to analyze and how it is inherited (is it dominant or recessive, sex-linked, co-dominant or so on)
