Answer:
<em>The correct option is D) The four nitrogen bases of DNA combine is threes to produce only 20 amino acids.</em>
Explanation:
Our DNA is made up of four nucleotide bases. The genetic codon can produce 20 different amino acids based on the sequence. The genetic code which codes for a certain amino acid remains the same for all types of organisms whether be prokaryotes, animals or plants. Hence, the genetic code is considered universal as the four nitrogen bases combine to form only the 20 different amino acids in all types of organisms alive.
I think b, because it’s the time that the isotope takes to fall to half of its original value
As DNA replication begins the DNA molecule is broken apart into two complementary strands
hope this helped :)
Answer:
For each ball, the crater diameter increased as the height of the ball drop increased. My conclusion is that crater diameter increases with increasing mass. Also as the height of the ball increases, so does the crater diameter. Thus crater diameter is proportional to the mass and velocity of the impactor.

correct me if im wrong!:-)
Natural selection, random genetic drift, mutation, population mating structure, and culture.
