Hi,

If a point mutation occurs during which  CGA changes to AGA, the mutation will be simply inherited to the offspring and there won't be any harsh effects on the health of individual.

This is because, both AGA and CGA code for same amino acid called Arginine.

We know that mutations posses harmful effects when they change the genetic sequence leading to the incorporation of incorrect amino acid in the organisms and their offspring. But in this case the mutation will not be harmful and will simply be transferred to the offspring and will have no effect on the functioning, fitness or survival of the organism

Hope it helps!:)

Answer:

Your bloodstream.

Explanation:

The cells in your pancreas produce insulin which needs to be sent to the rest of your  body to tell your cells to take in glucose (sugar) for energy. In order to get sent out of  the pancreas' cells, the insulin needs to go through your bloodstream.
