Answer:
Ecologists
Explanation
often estimate the size and density of populations using quadrats and the mark-recapture method. A population can also be described in terms of the distribution, or dispersion, of the individuals that make it up. Individuals may be distributed in a uniform, random, or clumped pattern.
Answer:
The relative age of a fossil can be determined by comparing its <u>Index fossils</u> to other fossils within the same rock layers below younger fossils.
Explanation:
Relative dating is one of the two methods used to determine the age of fossils does not determine when events occur, but it shows the order of the events as they occur. Relative dating compares similar rocks and fossils of already known ages to the ones the fossils that are yet to be determined so as to get their approximate age. The relative age of a rock is the age of that rock when compared to the ages of other rocks.
A fossil record can show the relationship that existed between different plants and animals. Often we Index fossils are used in dating other fossils found in the same strata. Index fossils point out the relative age of the layer where it is found,

Hope This Helps! And that I wasn't too late!
Adenosine triphosphate (also called ATP) is used by the cell as fuel to
pump sodium out of the cell during the process of active transport. It
carries energy to the areas of the body where it is needed. It is
necessary for many of the cell's functions and is an important part of
metabolism.
Answer:
Four conditions are needed for natural selection to occur: reproduction, heredity, variation in fitness or organisms, variation in individual characters among members of the population. If they are met, natural selection automatically results.
