Question

32/35
which of the following describes homeostasis?
keeps variables exactly at the set point
organisms ability to maintain steady(stable) internal conditions
acts to keep values outside of a desired range
operates through positive feedback

Explanation:

To determine the correct description of homeostasis, we analyze each option:

• The first option is incorrect because homeostasis does not keep variables exactly at a set point but within a range.
• The second option is correct as homeostasis is defined as an organism's ability to maintain steady (stable) internal conditions, such as temperature, pH, etc., within a tolerable range.
• The third option is incorrect because homeostasis acts to keep values within a desired range, not outside.
• The fourth option is incorrect as homeostasis mainly operates through negative feedback (positive feedback is less common and not the primary mechanism for maintaining stability).

Answer:

B. organism's ability to maintain steady(stable) internal conditions
