How do mitosis and meiosis benefit a organisms survival 100pts and brainliest

See explanation below.

Explanation:

Mitosis is the duplication of cells in the bodies of plants and animals. All cells can undergo mitosis. Mitosis benefits the body by replacing cells as needed. The skin for example loses a lot of cells. Mitosis is when cells reproduce - and results in an exact copy - to replace the cells that are lost or need to be replaced for other reasons.

Meiosis is the duplication of cells that are not alike. In Mitosis, the duplicate cells are an exact copy, with a full exact copy of the body's DNA. In Meiosis, the new cells are different in that each one has half of the DNA - or half the number of chromosomes. Meiosis allows for the creation of cells that allows for sexual reproduction. Meiosis is the process that creates sperm and eggs. These cells are known as haploid cells - in that other cells are known as diploid, with full DNA and cells that have gone through the meiosis process have half and are known as haploid cells.
