Which situation would most likely result in evolution?
a. a single individual dies in a large population.
b. a large population continues to grow larger.
c. a green parrot had an allele for green feathers and an allele for blue feathers.
d. a butterfly predator sees yellow more easily than it does green, and a population of butterflies includes both phenotypes.

D. A butterfly predator sees yellow more easily than it does green, and a population of butterflies includes both phenotypes.

Explanation:

The butterflies would attempt to stop being attack by evolving to have many more green butterflies.

The correct answer is D. A butterfly predator sees yellow more easily than it does green, and a population of butterflies includes both phenotypes.

Explanation:

Evolution occurs due to the selective force of nature. So here the selective force is a predator and the population which is more adapted to their environment will be selected over less adapted population.

So as yellow can be seen more easily than green, therefore, chance for picking yellow butterfly is more than the green. So as green butterflies have required adaptation or traits that help them to protect against predator, therefore, it will lead to their evolution.

c. live where it’s cold and icy

in a chemical reaction, the atoms and molecules produced by the reaction are called products. no new atoms are created, and no atoms are destroyed. in a chemical reaction, reactants contact each other, bonds between atoms in the reactants are broken, and atoms rearrange and form new bonds to make the products.
