Answer:
On the basis of the given information, the six goldfish are taken in distinct sized aquarium to examine the influence of habitat space on the rate of survival of the fishes. The kind and amount of food, cleanliness, and temperature are maintained similarly.
Thus, with the help of the information one can state that:
A. The size of the aquarium is the independent variable.
B. The number of fish survived after six months is the dependent variable.

Viruses are acellular.
Explanation:
Viruses do not have cells, so we can say that viruses are acellular organisms, the structural and functional unit of living things.

Viruses are only able to reproduce within a host cell. For this reason we say that they are obligate intracellular parasites.
