They are measuring the time that two species have been evolving independently.

A molecular clock is a method that is used by scientists to estimate the time that two species evolve separately using the knowledge of the DNA differences. To carry out this method, scientists use (i) an estimate of the number of genetic mutations that occur between two closely related species and (ii) the average genetic mutation rate to estimate the time in prehistory when the two species split.

<h2>Homeotherms Method</h2>

Explanation:

Homeotherms is right answer

Homothermy or homeothermy is thermoregulation that keeps up a stable inner internal heat level paying little mind to outside impact
This inside internal heat level is regularly, however not really, higher than the prompt condition
The encompassing temperatures increment, homeotherms utilize evaporative cooling through perspiring as well as gasping to control internal heat levels, and also vasodilate surface blood vessels to promote heat loss

Does facilitated diffusion use energy

alexandr402 [8]

Facilitated diffusion does not use cellular energy.

Since the transportation of molecules occurs through the concentration gradient, it doesn’t use cellular energy for transportation of molecules.
