Detailed explanation-1: -Homeostasis in an organism or colony of single celled organisms is regulated by secreted proteins and small molecules often functioning as signals. Homeostasis in the cell is maintained by regulation and by the exchange of materials and energy with its surroundings.

Detailed explanation-2: -In homeostasis, body levels of acid, blood pressure, blood sugar, electrolytes, energy, hormones, oxygen, proteins, and temperature are constantly adjusted to respond to changes inside and outside the body, to keep them at a normal level.

Detailed explanation-3: -Homeostasis is important for maintaining stable internal conditions despite a changing environment. All cells must maintain homeostasis to stay alive.

Detailed explanation-4: -Homeostasis refers to an organism’s ability to regulate various physiological processes to keep internal states steady and balanced.
