Rabbits' intestines help in the digestion of cellulose, which is a time-consuming and complex process. To digest cellulose, rabbits require enzymes produced by bacteria living in their intestines. These bacteria break down the cellulose into simple sugars that rabbits can digest. Which of the following is an accurate statement about the survival needs of both rabbits and the bacteria that live in the rabbits' intestines? (A) Both the bacteria and rabbits get energy from sugars, and both must eliminate wastes. (B) Both the bacteria and rabbits get energy from sugars, but only rabbits need to eliminate wastes. (C) Both the bacteria and rabbits need nutrients, but only rabbits need water. (D) Only rabbits need nutrients and water; the bacteria do not need nutrients or water.

The size P of a certain insect population at time t (in days) obeys the function \( \mathrm{P}(\mathrm{t})=200 e^{0.06 t} \). (a) Determine the number of insects at \( \mathrm{t}=0 \) days. (b) What is the growth rate of the insect population? (c) What is the population after 10 days? (d) When will the insect population reach 320 ? (e) When will the insect population double? (a) What is the number of insects at \( \mathrm{t}=0 \) days? (b) What is the growth rate of the insect population? \% (c) What is the population after 10 days? Approximately \( \square \) insects. (Do not round until the final answer. Then round to the nearest whole number as needed.)
