i think its simple enough, but im not quite sure.

If two parents with dominant phenotypes produce an offspring with a recessive phenotype, then
(a) both parents are heterozygous
(b) one parent is heterozygous
(c) both parents are homozygous
(d) one parent is homozygous

im guessing its either A or B, along with answering the question, umm can anyone give me detail on wat they mean by both parents with dominant phenotype? may i have an example?

surely it has to be a definate moment in time right? an exact point, like conception, or is it at birth. no obviously the baby is alive before birth, but there cannot be a gray area for the beginning of life, so when is it?

It really sucks when you get old, you lose your looks and abilities. You think we will ever slow or stop the process? Here is a couple pics of what happens to you.

scientific principles/concepts that were espoused in the first Jurassic Park film from 1993 are plausible? Like, when the scientists extracted the blood from fossilized ancient mosquitos and then were able to do this and that and this and that and then come up with dinosaurs. Spielberg did make it almost look plausible. Now, I'm not gullible enough to actually think that this could work, but I am a bit of a dreamer/optimist. In theory, could any of that pseudo-science work? And could we in fact bring back an extinct species of animals that way?

Does it remain a water molecule until it is expelled from the body in urine or sweat or whatever, or is it broken down into H and O and these elements are used by our bodies?
