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.

Explanation:
WORKING DISTANCE is space between the bottom of objective the lens and the surface of the slide.
The distance between front edge of the objective and the lens and the specimen surface ("with the surface of the cover glass in case of the cover glass objective lens") when the specimen is also focused.
The working distance (W.D.) which is determined by the linear measurement of the objective and front lens to the focal plane. In the general, the objective of the working distance decreases by the magnification and the numerical aperture of both increase. The working distance is the distance and from the front of the lens to be the focal plane
