The correct answer is C. Estivation
Explanation:
In biology, estivation refers to a lethargic state that is mainly prompted by high temperatures, different from hibernation that occurs in the winter or at low temperatures. However, as hibernation estivation implies the organism of animals lowers the metabolic rate with the purpose of avoiding to die due to the high temperatures and the lack of resources including water. This can occur in both vertebrate and intervertebral animals including small animals. This implies, the mouse described which is a small animal probably is going through estivation as due to hot temperatures the organism lowers the metabolic rate, which is exactly what occurs in this process.
A radioactive isotope decays at a constant rate proportional to the number of radioactive atoms remaining. A simple way of describing the speed of decay is to see the time it takes for half of the atoms of a radioactive parent to decay and form the daughter element(s). This is called the half life.
