The answer is b because it's morphological
Answer:
Explanation:
The detailed steps are as shown below
- but magnitude of force F = √ [ 1 - v²/c²]
but acceleration twice as great as the force required to produce the same acceleration;
4 = 1 / [ 1 - v²/c²]
1/4 = 1 - v²/c²
v²/c² = 3/4
v/c = √ [3/4]
v = 0.87c
but speed of light c = 3 x 10^8m/s
v = speed of the particle = 0.87( 3 x 10^8m/s)
v = 2.61m/s
Answer:
1) Macrophages ingest antigen 2) Helper T cells are activated 3) B cells differentiate into plasma cells and memory cells.
Explanation:
Innate immunity and adaptive immunity provide protection against foreign invaders. Innate immunity is non specific and adaptive immunity is specific immune response; includes the production of antibody after a sequence of events.
- When an antigen enters the body the phagocytic cells such as macrophages and dendritic cells ingest the antigen by a process called as phagocytosis. These cells act as antigen presenting cells and present it to T cells.
- T cells are of two types T helper cells and T cytotoxic cell. T cytotoxic cells killed the affected cell such as affected by virus while T helper cells signal for the production antibodies.
- Antibodies are produced from the plasma cells while memory cells act as record keeping. The plasma cells are stimulated by interleukins.
