Answer:
Molecules of gas starts movement when they get energy from the sun in the form of heat.
Explanation:
Molecules of gas absorbed heat energy coming from sun. This heat energy is converted into kinetic energy due to which gas molecule moves faster. Volume of gas molecules also increases due to expansion of molecules by the absorption of heat energy. So more space is occupied by gas molecule as compared to liquid molecules.
The molecular clock is a scientific technique which presents a means of estimating evolutionary rates and timescales using genetic data. It uses mutation rate of biomolecules when two or more life forms diverged to estimate the time. Answer is B.
