The first one is 2, The answer to question 2 would be: <span>gene splicing or cloning
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. </span>This was called gene splicing.
Then the bacteria have insulin genes, the bacteria will be cloned to make multiple colonies of same bacteria. This phase called cloning.
and the last one 2, mitochondria.

How is meiosis related to natural selection
Meiosis creates genetic variability in a population, this means that more and more organisms have different traits. Some of these traits make an organism better adapted to survive in its environment. Those with these traits are more likely to survive (natural selection).
A scientist who studies the interactions or interrelationships between organisms and their physical environment is an Ecologist.
