Answer:
- is a required characteristic for living organisms
- is controlled by the hypothalamus in animals
- only occurs at the organism level
Step-by-step explanation:
Homeostasis is the condition of relative stability that the body needs to perform its functions properly for the body's balance. Homeostasis: word of Greek origin, whose meaning already defines very well what it becomes: homeo- = similarity; -stasis = putting in, stability.
Despite changes that may occur in the body, internally or externally, homeostasis is the constancy of the internal environment (interstitial fluid). Keeping it at an adequate temperature (37ยบ C) it ensures that the necessary exchanges for the body take place; and, thus, the cells of the body develop.
Those responsible for controlling homeostasis are the nervous system and the endocrine glands. For example, insulin (which is a hormone) acts to reduce glucose levels when it is too high. Another example: In the case of an increase in body temperature, the sweat glands are caused to release more sweat; for they receive the command of nerve impulses; that way, the body is cooled.
In summary, we can say that homeostasis:
- is a required characteristic for living organisms
- is controlled by the hypothalamus in animals
- only occurs at the organism level
