What is the theory of punctuated equilibrium?
a) it describes one way that new species arise.
b) it explains why mass extinctions occur.
c) it describes the rate of geologic time.
d) it explains how domestic animals evolved.

The correct answer is option a.

Explanation:

Punctuated equilibrium refers to a term, which signifies the change in evolution of animals and plants in a comparative static manner. In contrary to the concept that life forms modify gradually with time in response to their surroundings, the theory of punctuated equilibrium states these changes takes place in shots of time intermittently.  

The term stands in contrary to Darwin's more dynamic evolution model. The punctuated equilibrium suggests that evolution only occurs in bursts of time, which are brisk.  

homeostasis is the tendency towards a relatively stable equilibrium between interdependent elements, especially as maintained by physiological processes. and this is how it applies to the integumentary system. back to top. skin functions in homeostasis include protection, regulation of body temperature, sensory reception, water balance, synthesis of vitamins and hormones, and absorption of materials. when body temperature falls, the sweat glands constrict and sweat production decreases.
