Answer: B) R group
Explanation: An aminoacid is composed by an amino group, an acid or carbonyl group and a side chain or R group, all bonded to a central carbon atom. Aminoacids are different between them for the R group and can be classified as: 1) Non-polar Neutral if the side chain is uncharged and non-polar (aliphatic or cyclic). 2) Polar Neutral if the side chain contains amida, sulfur or hydroxyl groups. 3) Basic if the side chain contains other amino groups. 4) Acid if the side chain contains other carboxyl groups.
Atoms with the same number of protons
Genetic modification allows for foods to grow larger in a shorter amount of time. This allows growing populations to provide the necessary amount of food. Using modification, you can also reduce the need for pesticides.
B. Cladistics, because the other two choices don't make any sense.
Answer:
-29.5
Explanation:
We were given two equations:
2x + 3y = 6 and -43 + 3y = 12
Using the second one, we get:
3y = 55
y = 18.3333
Then plugging that into the first one:
2x + 55 = 6
2x = -49
x = -29.5
