In a variational process of evolution, as described by darwin, the properties of a trait in a population change because: a. each of the individuals in the population change in that trait. b.some of the individuals in the population change their trait by a small amount and others by a large amount. c.whether or not an individual in the population changes its trait varies depending on the environment where that individual lives. d.none of the individuals in the population change, rather which individuals remain in the population changes.

Option (c).

Explanation:

Darwin is known as the father of evolution and explains the theory of the natural selection. He explains the relationship between the evolution and the natural selection.

According to Darwin the population with more reproductive power has high chance of fitness and adapt in the environment. This is because the large number of individual in the population shows large variation with the variation in the fitness when subjected to the process of natural selection. The changes or the variation in the trait mainly depends upon the environmental condition of the individual.

Thus, the correct answer is option (c).

during the process of dna replication, brdu can replace thymidine and incorporate into the newly synthesized dna, cell proliferation thus can be reflected in the extent of brdu incorporation.

c. live where it’s cold and icy
