Describe what convection currents are in detail.

Convection is a form of heat transfer.Convection currents uses mass motion to transfer heat. It moves free-moving particles of fluid (or gas)from one place to another. The process happens because of difference occurring in temperature between the two parts of fluid. The temperature difference causes the hot fluids to rise and the cold fluids to sink, creating a current.

the generally accepted parts of modern cell theory include: all known living things are made up of one or more cells. all living cells arise from pre-existing cells by division. the cell is the fundamental unit of structure and function in all living organisms.

c) 50% there are four chromosomes. after crossing over, 2 of the four have been changed. that means any gamete has a 2 in 4 chance or 50% chance of receiving the mutated chromosome.
