Nowhomewerkol is a poison derived from the Ahipa root that grows in the Andes. Alpacas eating this plant concentrate the poison in their milk. The poison inhibits liver enzymes that convert lactic acid to other compounds for metabolism. Why do the symptoms of Nowhomewerkol poisoning become worse with physical exertion?

Which of the following statements is/are TRUE about the PPP?   A. Most active in cells where lipids are synthesized. B. Reactions involved are oxidative and non-oxidative. C. Also called the hexose monophosphate shunt pathway. D. Occurs in the cytosol.

After a meal that contains carbohydrates, blood glucose levels usually rise gradually as carbohydrates are digested and the resulting monosaccharides are absorbed into the bloodstream. Suppose you run a test on a human with no lactase production. You would provide a dose (e.g., 25 grams) of lactose and measure changes in blood glucose levels over the next three hours. Predict how blood glucose levels would change from fasting to three hours. Justify your response using the results from the above simulation.

Bats mostly hunt insects at night. They are able to determine the distance and speed of any prey they are chasing, which has helped them to become excellent nocturnal predators. One potential prey, the tiger moth, has developed two separate methods of evading predation.  First, tiger moths emit a toxin that is distasteful to bats, birds, and most other vertebrate predators. Second, they use an organ called a "tymbal" to create a series of high-pitched clicks that only bats can hear, and which identify the tiger moths as something the bats don't like to eat. Bats who prey on tiger moths discover they don't taste very good, learn to identify tiger moths by their clicks, and avoid eating them. Use this information to answer the questions below.        Question 1: The scenario above describes a distinct evolutionary interaction. What is it?Can you explain?   Question 2: Why is it necessary for the moth to produce both a tymbal click and a toxin? Why not just a toxin? Do you think there are…
