Answer:
c. protein from RNA
Explanation:
Translation is a process that occurs in the ribosomes where tRNA is used to read the mRNA strand and translate the codons into complementary amino acids.
Warmth and vegetation were the two big things. Since everything was ice, animals would've died of hypothermia or something, and the ice wouldn't allow any vegetation to grow. It's kind of like the dinosaurs; the plant eaters died b/c they didn't have any vegetation to eat, and the meat eaters died b/c they didn't have any meat to eat since the animals died. Same thing happened in the ice ages. Just with the added variable of freezing temperatures.
Answer:
Replication occurs in three major steps:
the opening of the double helix and separation of
DNA strands, the priming of the template strand,
and the assembly of the new DNA segment. During
separation, the two strands of the DNA double helix uncoil at a specific location called origin.
