<span>The answer would be; a significant increase in blood temperature.
The muscle contraction from exercise will produce heat that will increase the body temperature. In a hot and humid condition, this will make the body temperature hard to be lowered. The increase of blood temperature will influence the respiratory control center, makes the respiration drift upward.</span>
It seems that you have missed the necessary options for us to answer this question, so I had to look for it, so here is the answer. <span>If nondisjunction occurs, one of the resulting cells will receive</span> no homologues of a chromosome. Hope this answers your question.
Answer:

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.
As the population density increases therefore we probably have an increase in birth rate, aslo less space becomes available to individuals and if competition increases that means we probably have an increase in fighting (contest competition) therefore there might be an increase in individuals dying. Therefore I would say the answer is (c) the increase in population density would cancel out the competition. Hope this helps :).
