Answer:
Meiosis is a process in which sex cells, also known as gametes are made. Meiosis is different from mitosis in a lot of ways, one being that mitosis creates identical daughter cells and meiosis creates unique daughter cells. Meiosis is important because it allow for the creation of a meiosis nucleus. Cells produced by meiosis will be used in haploid, where each member of the next generation is genetically unique.
Cells produced in <u>sexual reproduction</u> will have half of the genetic information of body cells and will be genetically <u>unique</u>. This is necessary because when a sperm and an egg fuse together in sexual reproduction. They form a <u>zygote</u>: the first body of a new individual.
The new individual will now have cells that are <u>diploid</u>, meaning they have two sets of chromosomes. They zygote will have to do a lot of <u>mitosis</u> allowing it to grow quickly and ensure that all of its cells are genetically unique.

According to the scientist, the main reason that prolonged fasting is an enemy of the waist is that the meal set up after this period of scarcity is usually an example of caloric and nutritional imbalance - in the research, fasting usually occurred in the afternoon. “When they have access to food, the greedy individual does not make healthy choices,” explains the expert. Being deprived of energy, the body triggers a whole mechanism that favors the binge eating, the result is that the individual gets fat.
