As you age your physical functioning deteriorates This is most likely due to reduced efficiency in basic cellular processes One cause of this is thought to be?
Senescence
What is the programmed senescence theory of aging?
The programmed senescence theory suggests that aging is a genetically regulated process designed to limit the lifespan of an organism. It proposes that aging is a result of the activation of specific genes that control the aging process and ultimately lead to the deterioration of cells and tissues over time. This theory contrasts with the idea that aging is simply a result of accumulated damage and wear and tear on the body.
How may the degradation of telomeres result in cellular aging?
It is speculated that shortening of telomeres could be the cause of aging, or could be speeding the aging process up. It is known that telomeres preserve the life of the cell and may even extend the life of the cell. To understand how aging of the cell happens, we have to look back at the life of the chromosome. The cell divides and the telomeres continue to get shorter and shorter until it reaches such a critical length that the cell loses its ability to divide. Some cells might die or as mentioned earlier, they will lose their reproductive capability, or cellular senescence. Cellular senescence will have an overall affect on the organism, contributing to decline of tissue function that is the main trait of aging. Therefore, it is right to assume that telomere dysfunction which leads to senescence, has an effect on the aging process.
Underlying cause of the cellular effects of aging?
There are seven primary causes of aging. They are cell loss, nuclear mutations and epimutations, mitochondrial mutations, extracellular junk, intracellular junk, cellular senescence, and extracellular cross-links.
What is meaning of gitilon?
There is no widely recognized meaning or definition for the term "gitilon." It is possible that it is a made-up or uncommon word with no specific meaning.

What is the opposite of renaissance?
senescence
Senescence is the process of what?
aging.
State when a cell no longer divides?
Senescence
What is the aging of a plant called?
The aging of a plant is called senescence. It is the process of deterioration that occurs as a plant grows older and eventually leads to its death.
What part of plant hormones prevents senescence?
cytokinins

retirement, senescence
The leaves of a tree change color in the fall This is an example of a tree what?
senescence.
Define cell senescence in tissue culture?
Senescence is the period between maturity and death; as it relates to tissue culture this is the phase when confluence has been reached (assuming anchorage-dependant cells) and when the media contents contain waste and/or factors to an extent which causes the cells to begin to die-off en masse. The point of tissue culture, typically, is to avoid the senescence phase by regularly changing the media (to dispose of waste products which have toxicity effects), and by subculturing while in log-phase (before the chemical signalling that can cause senescence begins).
What are the 5 stages of?
the five stages are : childhood adolescence adulthood and senescence (old age)
