HELP PLEASE! MULTIPLE CHOICE

1. A species of beetle can be either black or brown in color. The beetle's color is determined by a single gene, and black is recessive to brown. The soil in the area has become darker and closer in color to the black beetles. Which of the following will most likely occur?


Selective pressures will decrease the number of brown beetles.

Selective pressures will increase the number of brown beetles.

Selective pressures will decrease the number of black beetles.

The overall size of the beetle population will continue to decrease over time.


2. Coral snakes are brightly colored, highly venomous snakes with red, yellow, and black bands along their bodies. Another species of snake, called the scarlet king snake, has similar bands of red, black, and yellow. Which of the following describes the conditions that resulted in a large population of king snakes with these types of markings?

King snakes and coral snakes relied on similar food sources that contributed to their unique coloring.

Since king snakes with these markings were avoided by predators, they were able to survive to pass on this trait to offspring.

Coral snakes mated with king snakes often enough to produce another species of king snake with the red, black, and yellow.

Overproduction of offspring increased the likelihood that the genetic mutation leading to these bands would spontaneously occur.
