Answer:
Gas exchange during respiration occurs primarily through diffusion. Gas molecules move from a region of high concentration to a region of low concentration. Blood that is low in oxygen concentration and high in carbon dioxide concentration undergoes gas exchange with air in the lungs.
Explanation:
The process of cloning effectively involves taking a cell from your body and turning it back into an embryo. The embryo would then either develop into a human being as has been proposed by various scientists around the world and which is currently banned, or it would be turned into a stem cell.
The correct answer is the interphase.
The cell cycle consists of three phases: the interphase (G1, S, G2) the mitotic (M) phase, and cytokinesis. <span>The first checkpoint of the cell cycle is G1 checkpoint which is between G1 and S phase when cell checks its size, nutrients, molecular signals, DNA integrity. The second checkpoint is G2, just before the mitotic phase, when cell checks DNA integrity and DNA replication. Those two checkpoints are the ones before division, other like M checkpoint is during the mitosis.</span>
