Answer:
Explanation:
Specific B cells are stimulated by helper T cells to transform into plasma cells that secrete antibodies and during this process, the important features that is added to the B cells transition into plasma cell is the abundant rough endoplasmic reticulum combined with properly developed Golgi apparatus in other for the plasma cells formed now from B cells to have the needed surface area for immunoglobulin (antibody) production.
Answer:
C) genetic drift.
Explanation:
Genetic drift is the random change in the frequency of alleles in a population due to random sampling. Many circumstances can lead to genetic drift for example bottleneck effect, founder effect, etc.
The bottleneck effect occurs when most of the members of a population die because of any natural disaster like flood, fire, etc. This can cause a certain allele to be lost in the remaining population because of losing major populations. So here due to hurricane half of the mammal population gets eliminated which shows it is an example of the genetic drift.
Both plant and animal development is seeded in the perspective that a cell divides itself to form a tissue and tissues grouped will become an organ and the organism itself. The cell hierarchial model is followed in the development in both of these diverse however seemingly similar organisms.
