homeostasis

Explanation:

An endocrine system refers to a series of ductless glands and organs responsible for the production and secretion of hormones that are used by the body for the performance of various functions such as metabolism, controlling growth, reproduction, mood, sleep, etc. These hormones are secreted directly into the circulatory system (blood) and then transported to the organs and tissues in the body.

Basically, the endocrine system contributes significantly to the state of homeostasis in the body.

Homeostasis can be defined as a process through which a living organism maintains a steady or stable physical, internal and chemical environment ideal to enhance life and proper functionality.

For example, if a person becomes infected with a pathogen such as a virus. The internal stimulus that most likely takes place in order for their body to maintain homeostasis is that their core temperature increases. This is simply because pathogens such as a virus do not thrive or survive in a hot environment; they're naturally allergic to high temperature (heat).

In conclusion, homeostasis is the term used to describe the maintenance of a constant internal environment or balance by living organisms such as humans and animals.

measuring light intensity

light meters can be used to measure light intensity. the meter is held at the soil surface and pointed in the direction of the maximum light intensity, and then the meter is read.

errors can be made when measuring light intensity by accidentally shading the light meter. the reliability of the results can be checked by taking many samples.
