Question

Which of the following statements most accurately reflects the biological aspects of aging in humans?

 

A. Aging is strictly caused by only genetic changes over time
B. Aging is strictly caused by physiological changes that have no genetic basis over time
C. Aging is the result of accumulation of genetic changes as well as non-genetic physiological changes over time
D. Aging is all in the mind, your age is just a number

Answer 1

There are genes that control longevity and these genes are conserved through out animal kingdom. However, aging is the outcome of multiple metabolic pathways that alter their effectiveness in the biological system as the function of time. Therefore, there is a genetic component and physiological weariness that contributes to aging, physiological ineffectiveness is modulated by environmental factors that sometimes augment it.
