Cell- <span>the smallest structural and functional unit of an organism, typically microscopic and consisting of cytoplasm and a nucleus enclosed in a membrane. Microscopic organisms typically consist of a single cell, which is either eukaryotic or prokaryotic.</span>
Answer:
One type of control that occurs at the DNA level is the regulator genes. The regulator genes synthesize a repressor molecule that binds to the operator and stops transcription of the structural genes. Whenever there is enough amount of structural genes made, a repressor molecule will bind to the operator region and stop further transcription.
One type of control that occurs at the RNA level is RNA splicing. By this method, different proteins can be made by a single RNA transcript.

Identification, communication, regulation of solute exchange through the membrane, and isolation of the cytoplasm from the external environment.
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.
