Which of the following accurately describes the life cycle of most gymnosperms?
a. seed cones contain ovules.
b. germinated seeds are haploid.
c. a pollen tube is used to prevent the fertilization process.
d. pollen grains undergo meiosis to form egg cells.

The correct answer is option A. Seed cones contain ovules.

The seed cones are the part of the gymnospems, in which the female part is present. The conifers are the gymnosperms, which produces cones. These cones can be classified in two types, pollen cone and the seed cone. The pollen cone contains the male reproductive part and seed cone contain female reproductive part.

"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."

gold i'm pretty sure i might be wrong
