The theory of evolution provides a number of insights:
-it tells us how the species are related
-it tells us how the species and populations react to the changes in their environment
With this knowledge, the scientists can predict how the species will react to the potential changes and support the positive changes (provide a good environment for the animals for example) <span />
Answer:
The gene for human insulin is inserted into the gap in the plasmid. this is done through the use of restriction enzymes and ligase to insert and close the plasmid. This plasmid is now genetically modified. The genetically modified plasmid is introduced into a new bacteria or yeast cell. The more the cells divide, the more insulin is produced as bacteria divides into two identical daughter cells like in mitosis.
Explanation:
Jet streams are fast moving air currents much like how a river is a fast moving water current so the answer is jet streams.
