Answer:
The main difference between prophase I and II is that during prophase 1, the pairing of homologous chromosomes or the synapsis allows the non sister chromatids to cross over at chiasmata, leading to genetic recombination between chromosomes. During prophase II,synapsis does not occur; hence, no genetic recombination takes place between the chromosomes
During Prophase I the Centrosome is duplicated during the interphase, which is a process prior to prophase while in Prophase II, the Centrosome is duplicated during the prophase II due to the lack of an interphase.

Answer;
Oxygen or an oxidizing agent to receive electrons must be present for oxidation to occur in chemical reactions.
Explanation;
Oxidation entails the loss of electrons from these molecules, causing them to become unstable and highly reactive and leading to their eventual reaction with and damage of cell components such as membranes.
-In redox reaction; The ion or molecule that accepts electrons is called the oxidizing agent; by accepting electrons it causes the oxidation of another species. Conversely, the species that donates electrons is called the reducing agent; when the reaction occurs, it reduces the other species.
