which statement best explains how the effect on a particular allele can change the genetic makeup of a population over time?
an allele that increased the chances of a member finding shelter will appear in a larger percentage of the next generation’s offspring.
an allele that increases the chances of a member cooperating with other members will appear in a larger percentage of the next generation’s offspring.
an allele that increases the chances of a member reproducing will appear in a larger percentage of the next generation’s offspring.

The correct answer is-

An allele that increases the chances of a member reproducing will appear in a larger percentage of the next generation’s offspring.

Change in genetic makeup of a population over time ( representing alteration in the gene frequency of the population) indicates that the population is evolving.

According to natural selection (an evolutionary process), individuals that are capable of adapting better (due to beneficial allele) in the changing environmental conditions, survive and increase their number through reproduction.

Over time, the genetic makeup of the population will be changed as the organisms that do not have beneficial allele for their survival, are eliminated from the population.

Thus, last option is the right answer.

the alkaline earth metals (beryllium (be), magnesium (mg), calcium (ca), strontium (sr), barium (ba), and radium (ra)) are a group of chemical elements in the s-block of the periodic table with very similar properties: shiny. silvery-white. hopefully this ? i didn't fully understand the question
