Hello!
An amino acid has five basic parts. An amino group, a carboxyl group, a central carbon atom, a hydrogen, and a R group.
The r group is the side chain specific to each amino acid. The r group varies between each kind of amino acid, while everything else stays the same. Therefore, the r group decides the identity of the amino acid.
Hope this helps! Let me know if you need a more specific explanation.
Answer:
Angle A = (12 × 9) + 12 = 108 + 12 = 120°
Angle C = (3 × 9) + 18 = 27 + 18 = 45°
Explanation:
if im not wrong this should be right
Answer:
B
Explanation:
the pH scale is based on the function
1x10-14
So since pH is neutral the concentration of OH and H must be equal hence the only option in which the concetration would [OH]{H}= 1x10-14 would be when both are equal so it cannot be a or d and when they are expressed in concetration so the only option is B.
