Answer:
The answer is D.
Explanation:
The example given in the question is an example of gene flow which can be described as the movement of specific genes from the the gene pool population to population.
The act of catching the bigger fish and letting the smaller ones escape is changing the gene pool of the North East Arctic Cod and causing the next generations to have smaller and smaller sizes which is given as the genetic variation decrease due to gene flow.
I hope this answer helps.
So that there is more gene variation. Let's say if they all had the same genes, one specific disease would be fatal for the species' existence since they would all be the same. The diverse gene pool allows species to develop different characteristics that can help them defend against disease
I can try? So the 1st one I think the answer is ‘contaminating...” -that one. The 2nd is “of pollution...”- that one. The 3rd is “the flowering plants...”- that one. The 4th is “the plants that could tolerate...”- that one. And then the last is ‘a population only...”. Hope this helps or works!
<em>The First one is 2, The answer to question 2 would be: Gene Splicing or Cloning</em>
<em>First, the gene that makes insulin is cut from human cells. After having the insulin gene, the scientist will put it inside bacteria so the bacteria will produce human insulin. This was called gene splicing. </em>
<em>Then the bacteria have insulin genes, the bacteria will be cloned to make multiple colonies of same bacteria. This phase called cloning. </em>
<em>and the last one 2, mitochondria.</em>
