The rod photoreptors in the eye are extremly sensitive to light. Rod cells sense light through a signal transduction cascade involving light-activation of a G-protein linked receptor that activates a g-protein, which activates cyclic GMP phosphodiesterase. How would I expect the addition of a drug that is an inhibitor of Cyclic GMP photodiesterase and a drug that is a non-hydrolyzable analog of GTP to affect in the rod cells? Please site your sources if you have any thanks

A friend of mine is adopting children and this question came to me. I was wondering if there were any examples of animals which adopt children of their own species (but not a blood relative.) For example, I heard of wolves that adopt dog puppies, but would it adopt another wolf pup?
