Angiosperms do not need water for fertilization. why? a) flagellated sperm travel to the ovary inside the pistil b) pollen stays inside the cone scales to fertilize eggs c) a pollen tube grows from the pollen grain into the ovary d) the sporophytes grow directly from the gametophytes

The answer is c) a pollen tube grows from the pollen grain into the ovary.

Pollen tube is used to transport pollen from the stigma of a flower to the ovary. Actually, pollen begins to grow into pollen tube when lands on the stigma. It grows until it reaches an ovule which is inside the ovary. This way it is secured that a nucleus of pollen will fuse with a nucleus of the ovule and that fertilization will occur.

dude i stopped reading after the first 7 words but hey you seem real smart thats awesome have a great day

"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."
