Answer:
If one link is stop working.
Explanation:
There are six points at which the chain of infection can be broken or interrupted and a germ can be stopped from infecting another people. The six links are the infectious agent, reservoir, portal of exit, mode of transmission, portal of entry, and susceptible host. If one of the link is broken or interrupted, no infection occurs in the body of an individual because all the links are attached to each other in the form of chain which can stop working if one of it stop working.

Answer:
Mitosis produces two diploid (2n) somatic cells that are genetically identical to each other and the original parent cell, whereas meiosis produces four haploid (n) gametes that are genetically unique from each other and the original parent (germ) cell.
Differentiated cells are important for various body functions because they are capable of performing specialized functions.
Cell specialization is the process during development by which different cell types are developed to perform specific functions.
Multicellular organisms usually have differentiated cells to carry out specific functions.
The process of cell specialization occurs as a response to the activation and expression of differential genes in different tissues/cell types.
For example, differential gene expression can lead to the differential expression of an integral transmembrane protein in the cell membranes of a given cell type, thereby this cell type is able to transport certain substances and/or ions inside and outside the cell.
In the human body, a well-known example of cell differentiation is the red blood cells, which are specialized cells capable of transporting nutrients and oxygen around the body.
