Answer:
Natural selection causes change in allele frequencies within a population.
So option A is correct one.
Explanation:
Natural selection generally work on an organism’s phenotype, or observable features. Phenotype is often largely a product of genotype (the alleles, or gene versions, the organism carries). When a phenotype produced by certain alleles helps organisms survive and reproduce better than their peers, natural selection can increase the frequency of the helpful alleles from one generation to the next – that is, it can cause microevolution.
Carbon sinks (the ocean is actually the largest carbon sink)
Mitosis is the process by which a parent cell divides into two daughter cells that are genetically identical to each other and to the parent cell. The parent cell of 10 chromosomes will end up becoming two daughter cells that each have a copy of those 10 chromosomes.
