Answer:
A
Explanation:
Pluripotency means the cell can grow to any part of the plant including the whole plants. This why meristematic stem cells are harvested from plants and used to make cultivars <em>in vitro</em>. Meristematic stem cell in plants are found in apical shoots and roots and are responsible for the growth of height and girth of the plants.
Answer:
There are 22 pairs of chromosomes that are not sex chromosomes (called nonsex chromosomes, numbered chromosomes, or autosomal chromosomes)
I think this happens when there is no gene flow or when the population is small. Small population, germ line mutation, beneficial mutation that gets into many progeny and is of high chance of luck. Genetic drift involves a process in which allele frequencies within a population change by chance only, as a result of sampling error from generation to generation. Genetic drift occurs mostly in small population since the infrequently occurring alleles face a greater chance of being lost.
Concentration gradient= the difference in the concentration of a substance between two areas.
