Homeostasis refers to a state of dynamic constancy.
|
|
|
Negative feedback loops are important in maintaining homeostasis of physiological parameters.
|
|
|
Homeostasis ensures that physiological parameters are maintained exactly at the set point value.
|
|
|
Homeostasis is not the same as hemostasis.
|
|
|
None of the above is true.

Detailed explanation-1: -Homeostasis does not directly influence the external environment, but rather is influenced by the external environment. The answer is b. Homeostasis involves the influencing of the external environment.
Detailed explanation-2: -Physiological homeostasis is the tendency of the body to maintain critical physiological parameters (e.g., blood glucose level, blood salinity, blood pressure, core body temperature) of its internal environment within specific ranges of values.
Detailed explanation-3: -Homeostasis is any self-regulating process by which an organism tends to maintain stability while adjusting to conditions that are best for its survival. If homeostasis is successful, life continues; if it’s unsuccessful, it results in a disaster or death of the organism.
Detailed explanation-4: -The primary components responsible for the maintenance of homeostasis can be categorized as stimulus, receptor, control center, effector and feedback mechanism.
