It is a genus (which is greater than a species but lower than a family) of extinct lamp shells, called brachiopods.
Given what we know, we can confirm that the basic idea resulting from these studies is that a creature's metabolism is related to its lifespan.
<h3 /><h3>How is metabolism related to lifespan?</h3>
From the studies done and the comparison of the lifespan of certain species in relation to their metabolic rates, scientists have noticed that <u>metabolism</u> and <u>lifespan </u>are inversely proportional. The <u>slower </u>the metabolism of an organism, the <u>longer </u>that organism can live.
Therefore, we can confirm that the basic idea is that a creature's metabolism is inversely proportional to its lifespan, meaning that the faster the metabolism, the shorter the lifespan of the creature in question.

The correct answer is microglia.
<span>Microglia is glial cells found in the central nervous system with the protective role. Because they are the resident macrophage cells, they act as the first and main form of active immune defense. Microglia is constantly cleaning the CNS for plaques, damaged or unnecessary neurons, and infectious agents, like viruses or other microorganisms.</span>
C. Dependent variable
The independent variable is what you want to change (ex amount of light given to plants)
The dependent variable is what changes because of the independent variable (ex the height of the plants)
So Independent is what you change, Dependent is what you measure
