Last year, drasko went hiking for five hours and found it quite difficult. he also has stiffness in his joints and hips. which biological theory of aging would theorize that drasko's aging was due to the decay of tiny cellular bodies that supply energy for cell function, growth, and repair?

The correct answer is a mitochondrial theory of aging.  

The mitochondrial theory of aging, an alternative of the free radical theory of aging, suggests that congregation of destruction to mitochondria and mitochondrial DNA result in aging of animals and humans. In such instances, there seems to be a significant oxidative destruction of the cells.  

This destruction results in the generation of decay in tiny cellular bodies, which offer energy that is required for cell growth, function, and repair.  

is this a psat question, if so do not cheat try your best.
