Mammals have cold-sensitive nerve cells, which respond to decreasing temperature and warm-sensitive nerve cells, which respond to increasing temperature. Detection of an increase in temperature leads to
A) a decrease in the frequency of nerve impulses from warm-sensitive receptors and an increase from cold-sensitive receptors.
B) a decrease in the frequency of nerve impulses from cold-sensitive receptors and no change in the frequency of nerve impulses from warm-sensitive receptors.
C) an increase in the frequency of nerve impulses from warm-sensitive receptors and a decrease from cold-sensitive receptors.
D) an increase in the frequency of nerve impulses from warm-sensitive receptors and no change in the frequency of nerve impulses from cold-sensitive receptors.
E) a large increase in the frequency of nerve impulses from warm-sensitive receptors and the breakdown and recycling of cold-sensitive receptors.

The Answer of Mammals have cold-sensitive nerve cells, which respond to decreasing temperature and warm-sensitive nerve cells, which respond to increasing temperature. Detection of an increase in temperature leads to
A) a decrease in the frequency of nerve impulses from warm-sensitive receptors and an increase from cold-sensitive receptors.
B) a decrease in the frequency of nerve impulses from cold-sensitive receptors and no change in the frequency of nerve impulses from warm-sensitive receptors.
C) an increase in the frequency of nerve impulses from warm-sensitive receptors and a decrease from cold-sensitive receptors.
D) an increase in the frequency of nerve impulses from warm-sensitive receptors and no change in the frequency of nerve impulses from cold-sensitive receptors.
E) a large increase in the frequency of nerve impulses from warm-sensitive receptors and the breakdown and recycling of cold-sensitive receptors.
