Answer:
Explanation:
1. a. Interphase is the phase of the cell cycle in which a typical cell spends most of its life. During interphase, the cell copies its DNA in preparation for mitosis.
b. The third phase is anaphase. This phase only takes about 0.8 percent of the cell cycle to complete, which is the shortest time required out of all the phases. During anaphase the sister chromatids, or the two identical parts of a chromosome, are pulled apart to opposite ends of the cell by the spindle fibers.
2. Mitosis is important for three main reasons: development and growth cell replacement and asexual reproduction.
- Development and growth. After meiosis has produced a gamete, and this has fused with another gamete to form an embryo, the embryo grows using mitosis. ...
- Cell replacement. ...
- Asexual reproduction.
The reactant that brings about the oxidation is called the oxidising agent, and that reagent is itself reduced by the reducing agent.
Oxidation occurs when a reactant loses electrons during the reaction. Reduction occurs when a reactant gains electrons during the reaction. This often occurs when metals are reacted with acid.
Oxidation is loss of electrons (OIL RIG). Therefore, an oxidising agent takes electrons from that other substance. Therefore, an oxidising agent must gain electrons.
Oxidation happens when an atom loses one or more electrons during a chemical reaction, meaning that its oxidation number increases. This is because the atom loses the negative charge of the electron, which is similar to gaining a positive charge, increasing the oxidation number.
