What is the relationship between viruses and their host cells during replication?
Viruses use the host’s replication processes to produce progeny virus particles.
Viruses divide inside the host cell to produce progeny virus particles.
Viruses have their own replication processes and do not need the host cell.
Viruses infect the host cell and destroy it completely.
The Correct Answer is A
Viruses use the host’s replication processes to produce progeny virus particles.
Viruses are obligate intracellular parasites, meaning that they require a host cell to replicate.
They hijack the host cell’s machinery to produce new virus particles.
Choice B is incorrect because viruses do not divide inside the host cell.
Instead, they use the host cell’s machinery to produce new virus particles.
Choice C is incorrect because viruses do not have their own replication processes and rely on the host cell for replication.
Choice D is incorrect because while some viruses may destroy the host cell during replication, this is not always the case and is not the primary relationship between viruses and their host cells during replication.

Correct Answer is A
Explanation
In a well-designed experiment, all variables apart from the treatment should be kept constant between the control group and treatment group.
This means researchers can correctly measure the entire effect of the treatment without interference from confounding variables.
Choice B) Independent variable and dependent variable is incorrect because these are not groups but rather variables.
The independent variable is manipulated by the experimenters while the dependent variable is measured to see if it changes as a result of the manipulation.
Choice C) Experimental group and non-experimental group is incorrect because a non-experimental group is not a term used in experimental design.
The correct term for the group that does not receive the treatment is control group.
Choice D) High level and low level of the independent variable is incorrect because these are levels of the independent variable, not groups.
In an experiment, there can be multiple levels of the independent variable, but they are applied to different groups (e.g. control group, treatment group).
Correct Answer is B
Explanation
Glycogen is the storage form of glucose in the human body.
It is a polysaccharide that is stored primarily in the liver and muscle tissue and can be broken down into glucose when the body needs energy.
Choice A is incorrect because starch is a storage form of glucose in plants, not in the human body.
Choice C is incorrect because fructose is a simple sugar, not a storage form of glucose.
Choice D is incorrect because cellulose is a structural carbohydrate found in plant cell walls, not a storage form of glucose in the human body.
