Answer:

<em>The correct option is B) as the light colored moths were seen and eaten, the allele for dark colour became more prevalent in the population.</em>

Explanation:

The process of natural selection tends to favour those organisms which are better adapted to live in an environment. Evolution changes the allele frequencies of a population over time depending on the traits favoured by natural selection.

Before the industrial revolution, the colour of the trees was lighter and hence, the light coloured moths were better adapted to such environments as they could hide from predation. After the industrial revolution, the colour of the woods of trees became darker. The light coloured moths were no more able to hide from their predators and hence their population declined.

MArishka [77]

An isolated colony on a selective medium is not considered a pure culture because inhibited organisms might be masked by the colonies. This statement is true.

On the basis of their constitution or usage, culture media can be classified into various groups; these include defined, complex, selective, as well as enrichment medium.

A selective medium consists of dyes or noxious substances/chemicals which inhibit the growth of specific microorganisms but promote the growth of other microbes.

A pure culture is a laboratory culture which contains a single species of microorganism. It is free from other microorganisms.

Since selective media affects the growth of distinct organisms differently, therefore, an isolated colony formed in such type of medium is not considered a pure culture.

An open stomate allows water to leave through transpiration, guard cells control the opening and closing of a stomata, stomates will close to reduce water loss and By opening and closing the stomata on the underside of the leaves.
