Question

dinoflagellates can perform photosynthesis and provide energy for themselves and for the coral that they live near. the coral provide protection to the dinoflagellates. this is an example of a
a) commensalistic relationship.
b) dependent relationship.
c) parasitic relationship.
d) mutualistic relationship.

question 11 (5 points)
the idea that viruses originated as genetic material that was able to move within a genome, eventually exiting a cell and entering another is the ____ hypothesis.
a) recessive
b) regressive

Explanation:

First Question (About Dinoflagellates and Coral Relationship)

In a mutualistic relationship, both species benefit. Dinoflagellates provide energy (via photosynthesis) to coral, and coral provide protection to dinoflagellates—both gain from the interaction. Commensalism (A) is one - sided benefit, parasitism (C) is one species benefiting at the expense of the other, and "dependent relationship" (B) is not a standard ecological interaction term for this type of mutual benefit.

Second Question (About Virus Origin Hypothesis)

The regressive hypothesis (or the hypothesis with the correct term from the options, accounting for a possible typo) suggests viruses came from genetic material that could move in a genome, exit a cell, and enter another. "Recessive" (A) is a genetic term for allele expression, not related to virus origin.

Answer:

D) mutualistic relationship.
