If you were to design a benchtop/countertop for a microbiology laboratory, would you design one with many notches and cubbies (depressions) to hold all of your supplies, or would you design a smooth surface benchtop/countertop?
A) A benchtop/countertop with many notches and cubbies
B) A smooth surface benchtop/countertop
A) A benchtop/countertop with many notches and cubbies
Feedback: A smooth surface prevents the accumulation of microbe-containing dust and is easier to clean.

Gehring tested the hypothesis that the Pax6 gene acts as a master regulator of eye development by engineering Drosophila Pax6 genes to be expressed in Drosophila antennae. What happened, and did it support or refute his hypothesis?
A. A compound eye developed on the antenna; this supports the hypothesis. B. A compound eye developed on the head; this supports the hypothesis. C. The antenna developed normally; this falsified the hypothesis. D. The antenna developed where the eye normally would be; this supports the hypothesis. E.

Why is the secretion of uric acid beneficial to organisms that live in hot and dry environments?
A. Uric acid has poor solubility in water so it will become concentrated during excretion as well as being relatively nontoxic. B. Uric acid can be readily reabsorbed by the urinary system so it decreases the amount of waste produced by the organism. C. Uric acid has a high degree of solubility in water so it will become concentrated during excretion as well as being relatively nontoxic. D. Uric acid has poor solubility in water so it will become concentrated during excretion which allows the organism to use it as a defense mechanism.
