- Wear-and-tear theory and cross-linkage theory
- Cross-linkage theory and free radical theory
- Free radical theory and wear-and-tear theory
What do both error (stochastic) theories and predetermined aging (nonstochastic) theories agree on?
What do both error (stochastic) theories and predetermined aging (nonstochastic) theories agree on?
- Aging is primarily caused by free radical theory.
- Cells in the body become disorganized or chaotic and are no longer able to replicate, and cells die. (correct)
- Aging is the result of wearing out over time because of continued use and trauma.
- The visible signs of aging, such as gray hair, are solely caused by cross-linkage theory.
