Cooling the body decreases thyroid hormone release, which in turn decreases metabolic and oxygen consumption rate.
<h3>What do you mean by Hormone?</h3>
Hormone may be defined as a chemical substance synthesized in the body that controls and regulates the activity of certain cells or organs.
Thyroid hormone is responsible for the regulation of metabolism such as energy expenditure, protein metabolism, thermogenesis, etc.
Therefore, cooling the body decreases thyroid hormone release, which in turn decreases metabolic and oxygen consumption rate.

<span>Newborns of many species, especially humans, spend more time in REM sleep (Mark me as brainiest! <3)</span>
Answer:
an outer cortex, a medulla in the middle, and the renal pelvis in the region called the hilum of the kidney. ... On the inside of the kidney, the renal pelvis branches out into two or three extensions called the major calyces, which further branch into the minor calyces.
Explanation:
Correct option is C. This evidence supports the claim that <u>natural selection</u><u> can produce new structures by </u><u>coupling together parts</u><u> of other </u><u>structures</u><u>.</u>

<h3>How are gene variants involved in evolution?</h3>
Evolution is the process by which populations of organisms change over generations. Genetic variations underlie these changes. Genetic variations can arise from genetic variations (also called mutations) or from a normal process in which genetic material is rearranged as the cell is about to divide (known as genetic recombination).
Genetic variations that alter gene activity or protein function can introduce different traits into an organism. If a trait is beneficial and helps the individual survive and reproduce, the genetic variation is more likely to be passed on to the next generation (a process known as natural selection).
Over time, as generations of individuals with the trait continue to reproduce, the favorable trait becomes more and more common in a population, making that population different from the ancestral population. Sometimes the population becomes so distinct that it is considered a new species.
