Which of the following questions could most likely be answered using molecular clocks? (2 points) which species of beetles are most closely related? how many species of beetles existed in the past? what processes cause beetles to become extinct? how long have beetles existed on earth?

Which species of beetles are most closely related.

Explanation:

Molecular clocks are often used to determine where species diverge. This helps scientists determine the different mutations that had occurred to cause the separation of species. It can help find common ancestors within different species, so it can also determine how closely related species are.

answer : a model is often used to explain and make things easier to understand when any scientific topic needs to be demonstrated and explained.

as in this case where a scientist wants to use a model to present the results of his detailed scientific investigation. he should do it as it will him to make the audience understand the concept in a much better way. also, it can be changed according to new scientific understandings.
