Question

Homeostasis is
A. The tendency of an organism to change with change in the environment.
B. The tendency of an organism to maintain stability by regulating the body's internal environment
C. Regulatory control of hormones in the body.
D. Plant and animal extract used for homeopathic medicine.

Answer 1

Hint:- The maintenance of the body's internal condition (both physical and chemical) is done by a process called homeostasis. The body's internal environment involves body temperature, extracellular fluid pH, blood sugar level, sodium potassium level maintenance, fluid balance, etc.

Complete step-by-step solution:-
There are five types of homeostasis found. These are blood sugar control, temperature control, concentration of gas, body fluid maintenance, and blood pressure maintenance.
The process which involves the maintenance of body glucose level is called blood sugar homeostasis. Blood sugar is controlled by a hormone called insulin. Insulin is secreted from the beta cells of the pancreas. Insulin is responsible for absorbing blood glucose. A high amount of glucose presence induces the production of insulin.
Temperature regulation or thermoregulation is two types of, named exothermic and ending thermic. Exothermic regulation involves the external source to maintain homeostasis. Example: reptiles use sunlight to regulate their body temperature. Endothermic regulation is done by the individual according to their need. This type of thermoregulation is found in warm-blooded animals.
Gas exchange is a major homeostatic function that is done by the respiratory system. The process (breathing) involves the intake of oxygen and the exit of carbon dioxide. The autonomic nervous system controls the breathing process.
Maintenance of osmolarity of body fluids and plasma is called bloody fluid homeostasis. Maintenance of body fluid involves both neural and endocrine regulations.
Both the cardiovascular system and the neural system involved in maintaining blood pressure.
Thus, option B. Tendency of an organism to maintain stability by regulating the body's internal environment, is the right answer.

Note:- In 1849 Claude Bernard first described the homeostasis mechanism. Homeostasis is required to maintain a constant optimal condition within the body to maintain it’s a natural function. The major purpose of homeostasis is to sustain the body function in constant according to internal or external changes.
