Question

which process represents a balance of glucose in the bloodstream maintained by insulin?
a. homeostasis
b. metabolism
c. osmosis
d. adaptation

Explanation:

• Homeostasis is the body's process of maintaining stable internal conditions, such as blood glucose levels, which insulin regulates by signaling cells to absorb glucose.
• Metabolism refers to all chemical reactions in the body, not specifically the balance of a single substance.
• Osmosis is the movement of water across a semipermeable membrane, unrelated to glucose balance.
• Adaptation is the process of adjusting to environmental changes over time, not short-term internal balance.

Answer:

A. homeostasis
