An example of a homeostatic response is: a. an increase in body temperature that results from fever. b. an increase in body temperature that results from involuntary shivering. c. a decrease in body temperature that results from shock. d. an increase in body temperature that results from exercise. e. the rising sun causing an increase in body temperature in a stationary animal

An increase in body temperature that results from involuntary shivering.

Explanation:

Shivering is the involuntary, rhythmic contraction of skeletal muscles. Extra heat is produced by an increase in metabolic rate( thermogenesis) particularly of the liver and skeletal muscles. The stored glycogen is broken down into glucose which can provide energy to the body. The metabolic rate increases.

try using substitution:

x + y - 6 = x - y. (i'm not giving you the exact answer). since 0 = x - y, then sub 0 in the equation with x - y. combine your like terms, and then use inverse operations, and you'll have your answer.
