Which of the following statements about degeneracy pressure is not true?
a) Black holes form when gravity overcomes neutron degeneracy pressure.
b) Degeneracy pressure arises from a quantum mechanical effect that we don't notice in our daily lives.
c) Degeneracy pressure can continue to support an object against gravitational collapse even if the object becomes extremely cold.
d) Degeneracy pressure can arise only from interactions among electrons.

d) Degeneracy pressure can arise only from interactions among electrons

Explanation:

Degeneracy pressure is the pressure a dense materials that is made up of fermions exerts. It is best explained using "Pauli exclusion principle" which says that no two similar fermions can be at the same quantum level. Degeneracy pressure is not dependent on temperature.

the skeletons of most mammals reach a certain size and then stop growing. however, many animals, including some mammals, keep growing throughout their lives. kangaroos, for example, just keep growing and growing until they die. also, the longer an animal lives the greater the chance it might catch some deadly disease.
