1,3,4 are correct

Explanation:

The real answer

if you would think back to what you've been learning this whole time

is

1.) They give clues about Earth’s climate in the ancient past.

ex: think about sediments and their purpose is to show the time the deeper you go the more you know

3.)Fossils show what Earth was like millions of years ago.

ex: basically supported by answer 1

4.)Fossils can be found in ice.

ex: if not why didn't you watch ICE AGE the movie!!!

XD JK

apparently even mammoths were found in the Ice completely fossilized

the answer to your question is sperm

"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."
