The mitochondrial theory of aging ties in closely with ideas about the role of free radicals in aging. In the mid-1950s, Denham Harman proposed that aging results from accumulated damage inflicted by free radicals â atoms or molecules possessed of a sole unpaired electron in their outer shells.o better understand the mitochondrial theory of aging, a little more background on mitochondria may be helpful. Mitochondria are rod-shaped, double-membraned cellular organelles around 0.5-10mM in length.
What do ringneck snakes eat? A: Ringneck snakes eat earthworms, skinks, snakes, salamanders, frogs, newts and slugs. They enjoy small rodents, such as voles, mice and shrews. Bugs such as ants, spiders, centipedes, beetles, crickets and grasshoppers are also a part of their diet. Most of the insects and vertebrates that they eat are relatively small.
1 In the wild, blue-tongued skinks eat flowers, berries, fruits, earthworms, and insects. They aren't very agile, but most of their prey is slow-moving. They have large teeth and strong jaw muscles, to allow them to crush snail shells and beetles.  These skinks will sometimes ingest small stones to help them digest food.
