The correct option is A.
Exocytosis is a type of vesicle transport which cells use to move substances out of their interior. It is an active process because it requires the energy of ATP to occur. The process of exocytosis move substances from the cell cytoplasm to the cell membrane.<span />
Ribosomes consist of two biomolecules that are connected together. Between 37 and 62 percent of ribosomes are made of ribonucleic acid (RNA). The remaining parts of ribosomes are made up ofprotein.
Answer:
Option A
Explanation:
Options
A. most populations were fixed for a single genotype, but genotypes varied among populations
B. average heterozygosity was declining steadily over time
C. individual populations were polymorphic for several loci and most populations were genetically similar to one another
D. all populations were fixed for the same allele at each locus studied
Solution
As per the study conducted by Templeton, it was found that human affect the biodiversity at all biological levels such as genetic, ecosystem, species etc. and behind genetic variation two important factors are genetic drift and gene flow.
Both the gene flow and genetic drift produce opposite results as genetic drift increase variation with in the species but decrease variation with in the local population and the opposite of this happens in gene flow.
Genetic drift has actually lead to speciation of collared lizards among themselves for a specific genotype
Hence, option A is correct
