Answer 1

The correct answer is all individual variation is due only to environmental factors.

Variations are necessary for changes, or evolution to occur. The basis of natural selection, which is the mechanism of evolution, is genetic variation. Within a given population, there is genetic variation that may or may not make an individual more adapted to the environment (or changes in the environment). A species with a great deal of genetic variability is more likely to survive in a changing environment.

Answer 2

Answer;

all individual variation is due only to environmental factors

A population of organisms will not evolve if all individual variation is due only to environmental factors.

Step-by-step explanation;

-Evolution of organisms is influenced by several factors which include; natural selection, random genetic drift, mutation, and gene flow.

-Mutation is a random heritable change in a gene or chromosome, resulting from additions, deletions, or substitutions of nitrogen bases in the DNA sequence. Gene flow works to decrease the variation between the two populations.

-Genetic drift is the random change in allele frequency from one generation to the next.. Natural selection is the process by which some organisms have a greater chance of surviving and reproducing than others due to features that are better adapted to the environment.
