Answer:
Newton's law's
Explanation:
Basically anything that has been proven to always be true
1.Every object in a state of uniform motion will remain in that state of motion unless an external force acts on it.
2.Force equals mass times acceleration
3.For every action there is an equal and opposite reaction.
The answer is B. Bacteria blooms and decreased underwater photosynthesis causes asphyxia, killing the fish.

Answer: E. Amino acids (and thus proteins) also have nitrogen atoms; thus, the radioactivity would not distinguish between DNA and proteins.
Explanation:
The Hershey-Chase experiment, is an experiment that demonstrated that the genetic material of phage isn't protein but rather it's DNA.
Based on the information given in the question, the experiment will not work because amino acids (and thus proteins) also have nitrogen atoms; thus, the radioactivity would not distinguish between DNA and proteins.
Therefore, the correct option is E.
After 10 years, the isotope would have had two half lives. For each half life, half of the material reacts. Therefore, after one half life, 50% remains. Then, after a second, 25% remains. D is the correct answer.
