1. What does selective toxicity refer to? Why are penicillins and cephalosporins low in toxicity for humans? 2. Why are so called 'superbug' strains of bacteria commonly found in hospitals? Cite two reasons why hospitalized patients taking broad-spectrum antimicrobial drugs are more likely to develop such HAI superinfections. Compare and contrast endotoxins and exotoxins. Why are exotoxins more potent than endotoxins? 3. Assume that you are responsible for decontaminating materials in a large hospital. How would you sterilize each of the following?...

If humans had evolved to live in an aquatic freshwater environment rather than evolving to live in terrestrial environments, what evolutionary adaptions would be necessary to maintain water and salt balances, and how would the osmoregulatory and excretory systems have to change? Write a brief description of the osmoregulatory and excretory systems of a human that adapted for an aquatic freshwater environment, and why it would look the way it does. Consider the following: What would be required to maintain...

EXERCISE 18.6 How Quickly Can Humans Hunt a Species to Extinction? Name: Course: Section: Date: The moa, a giant flightless bird, was hunted to extinction on New Zealand in the early 1400s. The human population of New Zealand was no more than 2,500 at the time when the moa went extinct. We can make some simplified calculations to see how many moas were hunted per year (a) Humans first settled New Zealand and began hunting moas in 1314. The last...
