Explanation:

Protons are positively charged sub-atomic particles that are in the nucleus of an atom and have a relative mass of 1. Neutrons have a neutral charge, meaning they have no charge, and are also in the nucleus of an atom with a relative mass of 1.Electrons are negatively charged particles that orbit the nucleus in electron clouds. They are said to have a relative mass of 0.

For example, a sodium atom is number 11 on the periodic table. The atomic number of sodium tells us the no. of protons contained within its nucleus as well as the number of electrons orbiting. So we can say that sodiun has 11 electrons and 11 protons. To determine the number of neutrons, simply subtract the number of protons from the mass number( found on periodic table)

23-11=12 neutrons

Major gene reshuffling takes place during what phase of meiosis?
ExtremeBDS [4]
The answer is prophase of meiosis I.

Meiosis is a reducing cell division during which the number of chromosomes is reduced by half in the daughter cells. It consists of meiosis I and meiosis II. Major gene reshuffling takes place during meiosis I. This exchange of genetic material between homologous chromosomes is known as the crossover. Homologous chromosomes are present only in the meiosis I. They pair up during prophase of meiosis I. When they are paired up during prophase I, it is obviously that gene reshuffling takes place during prophase I.
