Question

In a few generations, this population of beetles changed.which is the most likely explanation for the change? the beetle population moved to a greener habitat. a natural disaster almost caused the extinction of the population. the beetle population’s food sources decreased dramatically. a mutation resulted in a new color of insect.

Answer 1

The right answer is D.

The change in the population of lady beetles during the generations is due to the genetic variability of the population (also called genetic diversity).

The gene that has been diversified in this case is the color gene of the carapaces of insects. 2 alleles exist in this case (one for the green color and the other for the yellow color).

Answer 2

The most likely explanation for a decline after a population's increase in a specific are is the shortage of resources. The area becomes insufficient to meet the demands of the increased population so the population declines.
