Answer:
The correct answer is "the bottleneck effect".
Explanation:
The bottleneck effect, also known as a population bottleneck or genetic bottleneck, is defined as sharp reduction of a species population that occurs either by environmental effects or as a consequence of human activities. The dramatical crash the that population of American bison had due to hunting and other problems is an example of a species suffering the bottleneck effect.
Humoral immunity protects the body against extracellular pathogens and Cell mediated immunity protects the body from intracellular pathogens .
Humoral immunity: It is the process adaptive immunity manifested by the production of antibodies by B lymphocytes. It develops the bone marrow. B cells may be trigged to proliferate into plasma cells.
Cell mediated immunity: Cell mediated immunity is an immune response that does not involve antibodies but rather involves the activation of macrophages and NK cells.
Humoral immunity and cell mediated immunity works together with assistance from helper T cells, B cells.

Answer:
F plasmid.
Explanation:
Conjugation may be defined as the transfer of the genetic material from one bacterial cell to the another cell by the direct surface contact. This illustrate the phenomena of the horizontal gene transfer.
The plasmid is the extra chromosomal DNA present in the bacteria and can replicate independently of the chromosomal DNA. F plasmid or fertility plasmid is generally transfer during the conjugation process from F negative cells to F positive cells.
Thus, the correct answer is option (c).
Temperature affects the type of plants because different plants require different temperatures and precipitation levels. Such as in the case of cacti, they need very little precipitation and can withstand very high levels of heat.
