Which of these events occur as a result of a decrease in body temperature?
A
sweat is produced
B
your nails turn red
C
contraction of arrector pili muscles
D
all of these
Explanation: 

Detailed explanation-1: -Mammals have a residual effect from shivering and increased muscle activity: arrector pili muscles cause “goose bumps, ” causing small hairs to stand up when the individual is cold; this has the intended effect of increasing body temperature.

Detailed explanation-2: -In addition, our body thermoregulates using our hair. The arrector pili muscles contract (piloerection) and lift the hair follicles upright. This makes the hairs stand on end, which acts as an insulating layer, trapping heat.
