Answer:
The statement is false.
Explanation:
Epinephrine (also known as adrenaline) is a hormone and a neurotransmitter produced by the adrenal glands, it helps to regulate cellular energy metabolism and increases the heart rate.
Epinephrine adheres to certain receptors that are exposed on the surface of a large number of body cells. This receptor, called beta-adrenergic, is a receptor that is embedded in the plasma membranes of these cells. Adrenaline does not penetrate the cell, instead, joining for a short period of time to its receptor, induces it to release biochemical signals to the cytoplasm of cells. This steric change, affects the configuration of the cytoplasmic domain of the protein, this is the "link" of the receptor that protrudes in the cytoplasm.
Hydrologists are most likely to perform actions relating to estimating the amount of groundwater in an aquifer.
<h3>Hydrologists</h3>
Hydrologists are scientists that specialize in the study of how water relates to the various crusts of the earth.
Hydrology in itself refers to the branch of science that studies how water moves relative to the earth's crusts.
Thus, species identification, age of fossils, or extracting underground oils have nothing to do with the work of hydrologists.
