Question

Biologists often determine population density by capturing animals and marking them for later identification upon recapture. A biologist wants to use this method for a population census of desert mice. This will work if the _____.
A) mice are recaptured in the same location using the same trapping methods
B) mice deliberately return because the traps contain food
C) biologist waits a long time before resampling the population
D) mice are territorial

Answer 1

Answer:

I think the answer is A

Explanation:

Since the question states that they want to determine the population of the desert mice. You get the direct answer from just using context clues. Since population means one species in a certain area, it means that this method will work if the mice stay in the same area.
