Changes in the dna are called mutations. They can occur spontaneously. Mutations can only be passed down in gametes--sperm and egg cells. with Darwins theory at mind a mutation needs to pass the test of natural selection to remain in the gene pool. So purposly making mutation or altercations may end in diseases/illnesses or in some cases death because they body can not take it.....hope this helps if it doesnt im sorry!
They all have these traits: <span>Cellular organization, Reproduction, Metabolism, Homeostasis, Heredity, Response to stimuli, Growth and development, and <span>Adaptation through evolution.</span></span>
Presumably whatever their nutrition and health requires, for instance, if a tree frog requires fruit flies to maintain a healthy and balanced diet, then the conservation center probably feeds their tree frogs fruit flies.
It so should be A.
