its either The division cycle of most eukaryotic cells is divided into four discrete phases: M, G1, S, and G2. M phase (mitosis) is usually followed by cytokinesis. S phase is the period during which DNA replication occurs or In eukaryotes, the cell cycle consists of four discrete phases: G1, S, G2, and M. The S or synthesis phase is when DNA replication occurs, and the M or mitosis phase is when the cell actually divides. The other two phases — G1 and G2, the so-called gap phases — are less dramatic but equally important. hope this helped!!

Answer: b. The use of protein as an energy source is greater for endurance atheletes than those who body build or lift weights.
Explanation:
Proteins are the biomolecules. They are composed of polymers of amino acids. It is required by the body to repair tissues and build muscles, bones, and necessary component of skin, and cartilage.
The body of athletes require more protein than body builder or weight lifters. This is because during athletic practices like running, swimming and others the muscular mass should be strong enough to conduct long continous practice. The muscle mass is build up by proteins. The muscles may experience lack of oxygen during regular practice and may become weak. Thus require more protein so that the strength may remain maintained.
