Answer:
(B) DNA polymerase recognizing a "mismatched" base pair, like adenine and guanine.
Explanation:
In DNA, adenine is always paired with thymine and guanine with cytosine. The DNA polymerase has 3' to 5' exonuclease activity which is also called proofreading activity. If a DNA polymerase adds the wrong nucleotide, it can not be translocated post the mismatched nucleotide. The pause allows the 3' to 5' exonuclease activity of DNA polymerase to remove the mismatched nucleotide followed by the addition of a correct nucleotide.
Answer:
A skin cell from a frog has 26 chromosomes? but thats not one of the answers hm
Explanation:
A chemical formula is obtained from the number of atoms in a compound.
Chemical compounds are composed of atoms. The number atoms of each element in a compound determines the correct formula of the compound. Before I can write the chemical formula of any compound, I must first determine the number of each atom in the compound.
For instance, phosphorus trichloride contains one atom of phosphorus and three atoms of chlorine hence I would place a 1 in the box for P and 3 in the box for Cl.

Answer:
Impairment of photosynthesis
Explanation:
The major effect of oil spilage is that it impairs or hampers photosynthesis.
Photosynthesis is the process where green plants manufactures their own food in the presence of sunlight and water.
Water is denser than oil. Therefore, oil floats on the surface of water. Oil on water surface acts as a blanket to sheild plants away from receiving direct sunlight. Sunlight is very important during photosynthesis.
In the absence of sunlight, plants are unable to manufacture their food.
They are also unable to receive carbon dioxide from the environment.
