If the number of T-cells dies then the ability to activate B lymphocytes will also be lost as they help B-cells to secrete antibodies and macrophages to destroy the antigens.
T cells also helps in the activation of cytotoxic T-cells to kill the targeted cell which is affected by antigens.
hence, the correct answer is option A

Answer:
Cell membrane is a semi-permeable membrane that surrounds the cytoplasm.
Explanation:
Archea contains only 1 cell and they are prokaryotic organisms. They have a different molecular setting, thus making them different from bacteria.
Cell membrane of Archea:
- In archeal cell membrane, isoprene chains are connected to glycerol lipid monolayer,
- The cell membrane is either lipid bi layer or lipid mono layer.
- Archeal cell wall contains pseudo peptidoglycan.
Cell Membrane of Bacteria:
- In bacteria, the fatty acid chains are linked to glycerol.
- The cell membrane is a lipid bilayer.
- Bacterial wall contains peptidoglycans.
Answer:
10 per 1,000.
Explanation:
The death rate and birth rate affects the population dynamics of the particular area. The birth rate increases the population size whereas the death rate decreases the population size.
The death rate of a population can be calculated by the following formula:
Crude death rate = total death/ total population
Here, total death = 1,000 and total population = 100,000.
Crude death rate = 1,000/ 100,000 = 0.01 or 10 per 1,000.
Thus, the correct answer is option (c).
