Substitutions between leucine and isoleucine are much more common in proteins than substitutions between leucine and serine. How would you explain this observation? Consider all possibilities and suggest how you would distinguish among them.
Why would it make sense (in an evolutionary sense) that Substitutions between leucine and isoleucine are much more common in proteins than substitutions between leucine and serine?

New-model commercial airplanes are much more fuel-efficient than older models. How is it possible for airlines flying older models to make money when their competitors are flying newer planes? When answering this question, consider capital budgeting. If the old planes still make money, does it make sense to buy new planes, given how long it would take to make the money back from the purchase of new planes? Explain thoroughly.

1. Do you think the fact that most American CEOs are paid so much more than rank-and-file employees suggest CEOs are overpaid? Explain. 2. Japanese CEOs generally receive much lower levels of compensation than CEOs in the United States. Does this imply that U.S. CEOs are overpaid? 3. Is it obvious that $10 per thousand is too low of an incentive to pay for CEOs? Explain. 4. Does the observation that the stock price increases when the firms increase incentive...

Smoking remains more common in much of Europe than in the United States. In the United States, there is a strong relationship between education and smoking: well-educated people are less likely to smoke. Does a similar relationship hold in France? Here is a two-way table of the level of education and smoking status (nonsmoker, former smoker, moderate smoker, heavy smoker) of a sample of 461 French men aged 20 to 60 years. The subjects are a random sample of men...
