Answer:B
Explanation:
The circulatory system is made up of blood vessels that carry blood away from and towards the heart. Arteries carry blood away from the heart and veins carry blood back to the heart. The circulatory system carries oxygen, nutrients, and hormones to cells, and removes waste products, like carbon dioxide.

Human Immunodeficiency Virus -- this is HIV, the virus that causes AIDS.

Cold virus. The common cold is caused by a virus.
Out of the following given choices;
<span>A.
</span>The mouse has a completely different DNA sequence
than the other mice.
<span>B.
</span> The
substituted nucleotide has the same directions as the original nucleotide.
<span>C.
</span>Substitutions in the nucleotides of a mouse's
DNA never affect their phenotypes.
<span>D.
</span>DNA sequences don't determine the color of a
mouse's fur.
The answer is B. Most probably, the nucleotide substitution did not translate to a change in the
amino acid sequence in the translated protein. As you may be aware, most amino
acids are coded by more than one codon. For example, Leucine is coded for by CTT, CTC, CTA, CTG, TTA, TTG.
Therefore, a substitution, that causes a change to either one of the sequences will not
change the amino acid.
