Answer:
Eosinophils
Explanation:
If you have severe allergies, your white blood cell differential will show an elevated eosinophils (type of white blood cell) count. These are a type of leukocytes that are produced during an allergic reaction, parasite worm infestations and autoimmune diseases. They are used to fight inflammatory and allergic infections.

Answer:
B) a nonsense mutation; this is because a nonsense mutation results in the change of a regular amino acid codon into a stop codon, which ceases translation. This fits with the problem's description of the protein that causes the symptoms as too short, as translation is the process by which proteins/polypeptides are created. A missense mutation would not be the answer because it still codes for an amino acid, which would not shorten the protein. A duplication of the gene would probably just lengthen the protein or not affect its length at all.
Answer:
The answer is <em>C</em><em>y</em><em>t</em><em>o</em><em>s</em><em>i</em><em>n</em><em>e</em><em> </em><em>a</em><em>n</em><em>d</em><em> </em><em>G</em><em>u</em><em>a</em><em>n</em><em>i</em><em>n</em><em>e</em>.
Explanation:
In a DNA sequence, <u>A</u> will always <em>pair</em> with <u>T</u> and <u>C</u> <em>pair</em> with <u>G</u>.
