How long is the gestation period of a hippo?
Correct Answer
D. 8 months

The gestation period of a hippo is 8 months. This means that the female hippo carries her unborn baby for a duration of 8 months before giving birth.

A hippo's skin produces a red, oily liquid that acts as a natural sunblock.
Correct Answer
A. True
Explanation
Hippo's skin produces a red, oily liquid that acts as a natural sunblock. This is true because the red liquid, called "blood sweat," is secreted by special glands in the hippo's skin. It acts as a sunscreen by reflecting the sun's harmful ultraviolet rays and also has antibacterial properties that protect the hippo's skin from infections. This adaptation helps the hippo to stay protected from the sun's harsh rays while spending long hours in the water or under the sun.
