50 POINTS!!!!!

When researchers use a molecular clock, what are they measuring?
A) the time that two species have been evolving independently
B) the time that fossils have been buried
C) the number of neutral mutations in a genome
D) how long ago an organism went extinct

Answer 1

Answer: (A) the time that two species have been evolving independently.

Explanation: The molecular clock is figurative term for a technique that uses the mutation rate of biomolecules to deduce the time in prehistory when two or more life forms.

Answer 2

The right option is; A) the time that two species have been evolving independently.

Step-by-step explanation:

The molecular clock is an essential technique that is used by researchers to measure the amount of time that two species have separated from each other. When using the molecular clock, researchers use the average genetic mutation rate, and an estimate of the number of genetic mutations between an organism and another closely related organism in order to obtain an estimate of their age. The molecular clock also help scientists to date species (such as jellyfish) that do not fossilize well.
