To answer both Question 4 and Question 5, let's break down the process of mitosis and its functions.
Mitosis is the process of cell division, which allows cells to replicate and create new cells. It occurs in somatic cells, which are the non-reproductive cells in our bodies. Mitosis is responsible for various functions, including the ones mentioned in Question 4.
A) In Question 4, the correct function of mitosis is "to repair damaged tissue." Mitosis helps in the regeneration and repair of damaged or injured tissues by creating new cells to replace the damaged ones.
Now, let's move on to Question 5, which asks what replicates during mitosis.
A) The correct answer to Question 5 is "cells." During mitosis, the cells themselves replicate. This process results in the formation of two identical daughter cells, each containing a complete set of genetic material, organelles, and cytoplasm.
To arrive at these answers, it is important to understand the basics of mitosis, which involves the division of cells and its role in repairing damaged tissue.
