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.
Garter snakes, like all snakes, are carnivorous. Their diet consists of almost any creature that they are capable of overpowering: slugs, earthworms, leeches, lizards, amphibians, birds, and rodents. A common misconception is that they eat insects.hile some snake species do, garters do not. When living near the water, they will eat fish and other aquatic animals. The ribbon snake in particular favors frogs (including tadpoles), readily eating them despite their strong chemical defenses.[citation needed] Food is swallowed whole.
