A nutrient medium that has all of its chemical components identified and their precise concentrations known and reproducible is termed defined medium

Explanation:

A defined medium is a synthetic nutrient growth medium. In a chemically defined medium, all the chemical (organic and inorganic) components are identified along with their exact precise defined concentrations.

Since it applies known exact concentrations of chemicals, it is reproducible.

This growth medium is specially used for in vitro cell cultures of human cells.

Glucose salt broth, inorganic synthetic broth are chemically defined medium.

This medium provides the necessary nutrients (carbon and nitrogen sources) in the defined amount for the microorganisms to grow.

A chemically defined medium only contains chemicals and is devoid of any animal or plant sources of nutrients.

homeostasis is the tendency towards a relatively stable equilibrium between interdependent elements, especially as maintained by physiological processes. and this is how it applies to the integumentary system. back to top. skin functions in homeostasis include protection, regulation of body temperature, sensory reception, water balance, synthesis of vitamins and hormones, and absorption of materials. when body temperature falls, the sweat glands constrict and sweat production decreases.
