Choose examples to support your reasoning. Select all that apply. An increase in temperature may select against cold-adapted genotypes. A predator not eating a bright colored prey again because the previous time the taste was unpleasant. An increase in a population of one species may case the extension of another species with the same food ration. An introduction of a new food resource into the environment may cause a new species to appear. An introduction of a new species of predator may cause the evolution of new defenses in some prey species.

An increase in a population of one species may case the extension of another species with the same food ration.

An introduction of a new food resource into the environment may cause a new species to appear.

An introduction of a new species of predator may cause the evolution of new defenses in some prey species.

Explanation:

An increase in a population of one species causes the extension of another species with the same food preference because the high population specie eat all the food and no food source is available to the other  organism.  An introduction of a new food resource into the environment may cause a new species to appear due to availability of the type of food.. An introduction of a new species of predator may cause the evolution of new defenses in some prey species which helps them in their survival.

1) gene flow

- it is described as the transfer of genes from one population to another population so that frequency of gene is increased.

-a zebra migrates to join a different herd of zebras.

2) natural selection

- a mechanism of evolutionary change in which individuals with advantageous traits survive and reproduce whereas the others ( those that can not adapt) eliminate from the population.

-competition for sunlight leads to taller trees.

3) mutation

- permanent change in the nucleotide sequence of dna ( genetic material) that could have harmful or useful consequences.

-the dna of a snake changes to make its venom stronger.

4) genetic drift - it is a random phenomenon ( that occurs by chance such as fire) that results in change in the gene frequency in a small population.    

-a grassfire randomly sweeps through a population of buffalo and kills most of the animals.
