Homeostasis can require the control of many different variables in organisms. Homeostasis regarding internal body temperature is
Anna71 [15]

Answer:

The term homeostasis refers to balance, where an organism seeks to maintain the balance of the temperature of its organism in order to persist in life.

There are organisms that are considered ectotherms, with which they release heat to the external environment in order to balance said increase in temperature and not denature their own proteins (such as enzymes, structural proteins, receptors, second messengers, etc.). On the other hand, in the case of endotherms, take energy from the medium to increase your body temperature and maintain it, since otherwise you could enter hypothermia.

In the human organism these principles occur both, not simultaneously, but according to the external temperature in which the human is, ectothermic / catabolic processes in heat stages and endothermic or anabolic processes in the cold stage.

Explanation:

In simple words, endotherm is the heat taken from the medium and exotherm or ectotherm is the release of heat to the medium.

This is so simple in objects, but in living organisms these processes have a reason, and that is why we explained above, when looking for a constant temperature these processes are responsible for mediating balance.

Which innate immune system component uses mhc class i molecules directly in its defense strategy?
erica [24]

Natural killer cells are identify as a intracellular infection,especially from viruses, by the altered expression of major histocompatibility class (MHC) I molecule on the surface of infected cells.

Theses cells is a type of white blood cells. They are also called as natural killer . A blood stem cells goes through several stages to became a red blood cells, platelets, or white blood cells.

These Natural killer cells are innate immune cells which shows strong cytologist function against physiologically stressed cells such as tumor and virus infected cells.They are first line of defense against tumor and diverse range of pathogens. Work as a primary defect in human body.
