Answer:
A
Explanation:
Natural selection occurs when an environment makes organisms with certain traits more likely to survive and reproduce.
Asexual reproduction results in no genetic variation (meaning differences in traits, also called divserity). Genetic variation must be present for certain organisms to be better suited to their environment, because in its absence all organisms share the same traits. This rules out B, C, and D. I hope this helps :)
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.
If a set of data is highly precise, it generally "indicates that the data must have a high level of accuracy" although there can be other crucial factors affecting the data as well.
Consumers/producers: A surplus of consumers and a reduced amount of producers cause an ecosystem to collapse. Their are more mouths to feed then there is food
ANSWER:
D
EXPLANATION:
Both of their temperatures stay about the same throughout the experiment.
