Many new reproductive strategies developed during the evolution of terrestrial vertebrates. Which statement identifies one of these new strategies? A. Eggs develop without fertilization B. Eggs develop outside of a parent's body C. Eggs are laid by the female parent only D. Fertilized eggs develop away from the body of water

D

Explanation:

One of the reproductive strategies of terrestrial vertebrates is the ability of fertilized eggs to develop away from the body of water.

Water is very important for fertilization in aquatic organisms and one of the biggest challenges posed by migrating to the terrestrial environment is desiccation of the eggs. Terrestrial vertebrates are able to overcome these challenges by making fertilization of eggs internal and the ability of the fertilized eggs to develop away from the body of water.

The correct option is D.

"1. it should be, it has been for about 20 years, and it's really not much different in the end than breeding animals to have particular traits. there are always concerns about genetically engineered animals/plants affecting the environment in unexpected negative ways, but i can't think of an example where the fears didn't turn out to be baseless.  

first, as you point out, it would be a great advance in pharmacology, to be able to tailor drugs and their doses to me. the pros involve better medical treatment. the cons involve privacy issues like insurance companies denying coverage to people with genetic risk factors. looking at dna markers wouldn't affect the frequency of genetic diseases, but it would allow detection of them earlier. and ok, actually i suppose that if people used this information to avoid having children with genetic diseases, some might decrease in frequency."

not too sure but maybe in the hot springs.
