Answer:
The pressure of a gas in a closed container increases if the volume of the gas decreases. Pressure and volume have inverse relationship which means if one increases the other decreases and vice versa. If pressure increases, volume of a gas decreases because there are a lot of empty spaces present between gas particles which are filled when gas particles come closer to each other due to applied of pressure.
I would say New genetic combinations occur in body cells that can be passed on to offspring because there won’t be new genetic combinations from body cells that are fully developed.
The modern theory of evolution states that a basis for variation within a species is provided by mutations. It plays an important role in evolution. The best source of all genetic variation is mutation. It is important as the first step of evolution<span> because it creates a new DNA sequence for a particular gene, creating a new allele.</span>
