Answer:
GUA and GUG.
Explanation:
If you look at the attached genetic code, the wild-type glutamic acid (Glu) is coded by the codons GAA and GAG.
Valine (Val) can be coded by the codons GUU, GUC, GUA or GUG.
Sickle-cell hemoglobin arises from a single mutation, which causes the translation of Val instead of Glu. The only codons that code for Valine that differ in just one base with the Glu codons are GUA and GUG.
"Carpeting", and "furniture increased ventilation" inefficient indoor cook stoves "VOCs from paints".
Option: C
<u>Explanation</u>:
VOC's are really harmful solvents that are released in the air as the paint dries. The VOC's can create acute health symptoms which may result harmful after some time, like dizziness, headache, and many more. Generally, the long term effects are not that evident, but some VOC's are more carcinogens according to US environmental protection agency. Although, many paint companies claim that their paints are VOC free which is actually false. It might be true that the VOC is not present in the base of the paint, but when the pigment is added to the paint the VOC increases. Hence, carpeting, furniture, cook stoves and VOC's from paints are really harmful indoor pollutants.
