Mutations are important because they bring about A) death if the organism in which they develop
B) genetic variation needed for a population to evolve
C) benefits for the individual, not for the population
D) hardey-weinberg equilibrium within a population

B) genetic variation needed for a population to evolve

Explanation:

Mutations are important because they bring about the genetic variation needed for a population to evolve.

Mutation brings about changes in the DNA sequence of an organism. Most times, mutation results when an organism tries to adapt and evolve to unfavorable conditions. Mutation can originate from mistakes in DNA sequencing. It can also be due to environmental influences.

Samples collected with bias can have skewed data plots.

If a sample size is too small, the data can be skewed.

Collecting a large unbiased sample will ensure the data is representative and not skewed.
