Answer:
Nucleosidase
Explanation:
DNA and RNA function as genetic material in organism and proteins are synthesized on the bases of information stored in theses nucleic acids. However as these nucleic acids molecules are present in every cell so they also need to be digested and used as energy source.
- First, the pancreatic enzymes nucleases released from pancreatic acinar cells causes the breakdown of Deoxyribonucleic acid and ribonucleic acids into nucleotides.
- These nucleotides are degraded into nucleosides by phosphatase enzyme that remove the phosphate group from a nucleotide.
- Then hydrolysis of Nucleosides into base and sugar is caused by the enzyme Nucleosidase.
That would be Directional Selection so the answer is D.

The best answer choice is:
<span>a. </span>Learned
helplessness
<span>Explanation: Learned helplessness was studied by
Seligman as a potential animal model of depression. Learned
helplessness occurs when people or animals feel helpless to
avoid negative situations. Martin Seligman first observed learned
helplessness when he was doing experiments on dogs. He noticed that the dogs
didn't try to escape the shocks if they had been conditioned to believe that
they couldn't escape.</span>
