Question

Evolution, in the biological sense, is NOT described by which of the following?

A. It is defined simply as change over time.

B. It is genetic change in populations over time.

C. It requires genetic variation in the population.

D. It requires differential survival of individuals based on genetic factors.

E. It is described by all of the above.

Advantages of studying molecular variations include all of the following EXCEPT:

A. molecular data directly reflect genetic differences.

B. molecular data can be used to compare organisms of different species.

C. molecular data can be quantified.

D. molecular data can be collected easily.

E. Actually, all of these are advantages to studying molecular rather than phenotypic variation.

Answer 1

Ans1) Evolution, in the biological sense, is NOT described by:

A. It is defined simply as change over time.

Explanation- Evolution is a process of descent with a modification. Evolution is defined as the change in the inherited traits of a population of organisms through successive generations which relies on the process of natural selection

Rest all statements about evolution are correct.

Ans2) Advantages of studying molecular variations include all of the following EXCEPT:

E. Actually, all of these are advantages to studying molecular rather than phenotypic variation.

Explanation- molecular variations are used as the structure of molecules to gain information on an organism's evolutionary relationships. So molecular data are used to compare organisms of different species. The nucleotides differences within a gene or amino acid differences within a protein reflect the evolutionary distance between two organisms.

Nucleic acids and proteins are information molecules in which they retain information of an organism's evolutionary history, so it reflects genetic differences.

Also we can now easily, quickly, inexpensively and reliably sequence genetic material. So they are easy to collect and easy to quantify

Ps- An upvote would be highly appreciated
