Answer:
F. Both regulation and secretion
Explanation:
Through sweat glands and superficial blood vessels, the skin is able to cool the body and regulate its internal temperature.
The eccrine sweat gland, which is controlled by the sympathetic nervous system, regulates body temperature. When internal temperature rises, the eccrine glands secrete water to the skin surface, where heat is removed by evaporation.
Answer:
Binocular vision allows an animal to see and judge depth. Predators need this depth perception to track and pursue prey. In short, forward-facing eyes allowed our ancestors to see through the dense leaves and branches in their forest habitat.

Answer:
The predation pressure increases mate
Explanation:
Since the observation of the scientist goes in order to increase the coloration in males, because of the predation pressure, and as a consequence the females are attracted by this colored mates.
It will be expected that the increase in pressure, it will increase the colored in skin, and this could end in an increase of the number of mates per male.
Answer:
Due to the gravitational force of the sun and the moon the tides behave as blank waves.
Explanation:
Tides waves are usually the up and down movement of waves. Tides wave formed by the gravitational force of the Earth,moon and sun.the sun and moon’s gravitational force pulls up the ocean to tilts towards the earth because of this reason t the tides rise up and down. Moreover the waves in water sticks to its governing principle that 's why it makes sound
