At the end of the semester we discussed DNA damage and repair systems. Then we read some papers on gene editing tools because these tools depend on DNA repair mechanisms in the cell to complete the editing process. For one of the three major editing tools, ZNFs (Zinc finger nucleases), TALENS (transcription activator-like effector nucleases) or CRISPR Cas9 answer the following:      i. What are the components of the gene editing system? (2 pts)            (type answer here)     ii....

One of the key concepts we have discussed this semester is the concept of “Elasticity”. Generally speaking, elasticity is simply a measure of how responsive one variable is to a change in another variable. While we have focused on the “own price elasticity of demand”, the “income elasticity of demand” and the “cross-price elasticity of demand” this concept can be extended to a number of different situations. (10 pts) The demand curve for a product is given by Qx=1,000-2Px+0.02Pz,  where Pz...

Earlier in the semester, we discussed an experiment by Stanley Milgram in which participants, assigned the role "teacher," shocked a "learner," sometimes to the point of potential injury (or worse). This week, we discussed Cognitive Dissonance, the Justification of Effort, and the Justification of Cruelty. How might these concepts help you understand the results of Milgram’s experiments? (If you are struggling, I would suggest focusing on the theory of the Justification of Cruelty, but, if you have other ideas, that’s...

One general feature which characterizes those phyla which we think of as "higher animals" is a high degree of structural complexity. The bodies of animals like cats and crocodiles are dubdivided into a variety of specialized structures we call "organs." Organs with related functions are interconnected, forming organ systems. This exercise will focus on just one of those organ systems--one of the most obvious and easy to figure out: the digestive system. The general task of the digestive system is...

1. We discussed phage in the context of sausage fermentation; it is also a serious concern in many modern, high-throughput cheese fermentations. However, phage problems never occur during traditional sauerkraut or kefir fermentations. Why would this be the case? 2. Is phage likely to be a problem in beer fermentations? Why or why not?

Choose at least two of the ten theorists we have discussed this semester. Compare and contrast them by: (1) explaining their theories, while focusing on their similarities and differences, and - (2) choose a particular idea, theme, or question, such as: individual’s relationship to society, inequality, deviance, psychoanalysis, romantic love, individual freedom , etc. Consider how it is discussed by these two theorists. i am choosing Freud and Skinner
