Question

For each of the following, choose the term or phrase that best completes the sentence or answers the question:

The maintenance of constant internal conditions in an organism is known as:
a. Homeostasis
b. Negative Feedback
c. Structure Specialization
d. Adaptation

Answer 1

Homeostasis is the process by which organisms maintain a stable internal environment, compensating for external changes to keep physiological parameters around a set equilibrium.

Step-by-step explanation:

The maintenance of constant internal conditions in an organism is known as homeostasis. This biological concept refers to the body’s ability to maintain a stable internal environment despite external changes. The body achieves this by making constant adjustments that bring various physiological parameters back to a set equilibrium point. For instance, when environmental temperatures fluctuate, the body responds by thermoregulation, like shivering to generate heat, or sweating to release excess heat. Another example is the regulation of blood glucose levels after eating, where the body works to normalize these levels through insulin secretion.
