Biology

The correct answer is: B.a mathematical tool that biologists can use to predict allele frequencies and determine whether or not evolution is occurring within a population.

Explanation:

The Hardy-Weinberg Model is a mathematical tool used by biologists to predict allele frequencies in a population under ideal conditions (no evolution). It provides a baseline to compare actual populations and determine if evolutionary forces are acting on them. If the allele frequencies deviate from what is predicted by Hardy-Weinberg equilibrium, it suggests that evolution is occurring.
