A rancher is suspected of shooting wolves near Yellowstone National Park, and you have been enlisted to go have a chat with him. The rancher doesn't see any benefit to having the wolves there. What do you say?
A. "If there are no predators like wolves, just one pair of jackrabbits can quickly create a population with explosive, exponential growth. Wolves help reduce the carrying capacity, keeping the population at a reasonable level."
B. "If there are no predators like wolves, just one pair of jackrabbits can quickly create a population with explosive, density-dependent growth. Wolves help reduce the age structure, keeping the population at a reasonable level."
C. "If there are no predators like wolves, just one pair of jackrabbits can quickly create a metapopulation. Wolves help reduce the biotic potential, keeping the population at a reasonable level."
D. "If there are no predators like wolves, just one pair of jackrabbits can quickly create a population with explosive, logistic growth. Wolves help reduce the fecundity rate, keeping the population at a reasonable level."

Why would co-administration of a bacteriostatic drug interfere with the effects of penicillin?
A. Since most bacteriostatic drugs are produced from bacteria, but penicillin is produced from mold, the two drugs are incompatible with each other. B. A bacteriostatic drug produces interference in the ability of a bacterial cell to take in compounds from the outside environment. Penicillin must be taken in by the cell in order to have its effect, so this would directly inhibit it. C. Penicillin interferes with cell wall production/stabilization by cross-linking of peptidoglycan. As such, it only works when the cells are actively replicating and MAKING new peptidoglycan. A bacteriostatic drug works by shutting down replication, holding the cells "static." This would interfere with the mode of action required by the penicillin. D. The bacteriostatic drugs would bind directly to the penicillin, preventing both its uptake by the cell and its ability to perform its duty within the bacterial cell.
