HIV's genome of RNA includes the code for reverse transcriptase (RT), an enzyme that acts early in infection to synthesize a DNA genome off of an RNA template. The HIV genome also codes for protease (PR), an enzyme that acts later in infection by cutting long viral polyproteins into smaller, functional proteins. Both RT and PR represent potential targets for antiretroviral drugs. Drugs called nucleoside analogs (NA) act against RT, whereas drugs called protease inhibitors (PI) act against PR. Which of the following treatment options would most likely avoid the evolution of drug-resistant HIV (assuming no drug interactions or side effects)?(a) Use a series of NAs, one at a time, and change about once a week.

(b) Use a single PI, but slowly increase the dosage over the course of a week.

(c) Use high doses of NA and a PI at the same time for a period not to exceed one day.

(d) Use moderate doses of NA and two different PIs at the same time for several months.

Which two ions are most affected by aldosterone?a. sodium and potassium
b. chloride and bicarbonate
c. calcium and phosphate
d. sodium and phosphate

The ratio of the surface area to volume in a cell describes the ratio of the cell membrane to the cytoplasm. True or false?

This diagram shows that embryos of certain species develop almost identically in the earliest stages of embryonic development. These physical similarities indicate that there are also genetic similarities among these organisms. The physical and genetic embryological similarities among these organisms suggest that they A. descended from a common ancestor. B. have multiple vestigial organs in common. C. are members of the same genus. D. hunt and breed in similar habitats.
