netineya [11]

Answer:

An active site

Explanation:

  • Enzymes are biological catalysts that catalyze chemical reactions or biochemical reactions. They are substrate specific and each enzyme acts on a certain specific substrate.
  • <em><u>Enzymes contain a pocket-like structure called the </u></em><em><u>active site</u></em><em><u> where the substrate binds according to the induced-fit model.</u></em>
  • Upon binding of the substrate to the active site catalysis takes place and the substrate is converted to product. Enzymes remain unchanged after the reaction.

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.
