Anew pesticide has been introduced to the habitat of this population of beetles. one leaf contains 4 red bugs and 4 white bugs. the second leaf contains 4 red bugs and 1 white bugs. which describes the effect of this environmental change? decreased genetic variation increased genetic variation genetic drift gene flow

The answer is decreased genetic variation or A  

Explanation:

Because only the beetles that are immune to the pesticide will live thus reducing the genetic variation.

as resources become scarce because of population growth, the growth decreases after few years due to lack of resources and food.

just finished the test, the answer is d, greg is the least cost-effective because he charges the most for the project
