<h2>Cell Cycle
</h2>
Explanation:
Eukaryotes grow and divide by cell cycle.
The main parts of a cell cycle are an ordered series of events – Gap 1 or G1 phase, Synthesis or S phase, Gap 2 or G2 phase, and the mitosis or M phases.
Interphase period (G1, S, G2 phases) - cell grows by size, duplicates its content, replicates its DNA, and finally prepares for mitotic cell division
.
Mitosis and cytokinesis - formation of two identical daughter cells
Cell cycle is regulated by regulatory or restrictive checkpoints in the cell cycle which are activated with detection of a defective DNA.
Proliferation of undesired or cells with defective DNA like in case of tumor cells is controlled by the action of suppressing agents like p53 and cyclins.
The tumor suppressor gene protein p53 prohibits division of tumor cells. Cyclins regulate cell cycle by activation of the enzyme cyclin-dependent kinase.
Answer:
yaaa you knew that air is everywhere it moves
Answer: It has a lower concentration of water (25% water) than the egg (90% water). To reach equilibrium, osmosis causes the water molecules to move out of the egg and into the corn syrup until both solutions have the same concentration of water. The outward movement of water causes the egg to shrivel.
Explanation:
Answer: Hypoxia
Explanation: hypoxia induces the production of erythropoietin, which is a hormome produced by the kidneys to help increase the productiom of red blood cells in the body. In Jessica's case, she might be experiencing this due to a change in ultitide whereby her body needs more oxygen than it originally gets (crllular hypoxis), therefore, her body signals for more red blood cell production. The erythropoietin will then be secreted and more red blood cells will be formed by the bone marrow through the hormonal action.
