The correct answer is their blood lacks A or B antibodies.
People with type AB blood have A and B antigenes on the surface of red blood cells (RBCs). Antigen AB has no antibodies, thus, transfusion can be considered safe ( the serum of the recipient does not contain antibodies for the blood cell antigens of the donor).
They had to adapt to the heat and to learn to survive long periods without water
Answer:
1. When DNA is duplicated from mRNA which DNA, mRNA uses a <u>U</u> nucleotide instead of T.
2. If the mRNA sequence is GUACUGUAC, the DNA Sequence is <u>CATGACATG</u>.
Explanation:
1. The only thing that changes from a DNA sequence to an RNA sequence is that the thymine (T) in DNA is changed to Uracil (U) in RNA.
2. There should be no Uracil (U) in a DNA sequence–– only ATCG. Just matching with the given pairings.
G can transcribed to C.
C can be transcribed to G.
A can be transcribed to T.
U can be transcribed to A.
The concentration of carbon dioxide in the atmosphere will decrease over time as it will be stored in the trees instead.
C. during winter. They can't be dormant while blooming or when there's rain or in the spring
