Answer:
Cellular theory of aging
Step-by-step explanation:
The student is reviewing the aging process. One group of theories of aging involves the shortening of telomeres until a critical minimal length is attained and then senescence ensues. These theories are known as cellular theory of aging.
Cellular theories of aging states that human aging is the result of aging of cells,whereby a large proportion of cells have reached a terminal stage of cell division due to the minimal length of the telomeres. This will limit the body's ability to regenerate and to respond to injury or stress.
