Question

question 24 of 30
an experiment can show:

a. how one behaves naturally.

b. biological basis.

c. effectiveness.

d. cause and effect.

Explanation:

In scientific research, experiments are designed to manipulate an independent variable and observe the change in a dependent variable. This allows researchers to determine if there is a causal relationship (cause - and - effect) between variables. Option A is incorrect because experiments often involve controlled conditions that may not reflect natural behavior. Option B is incorrect as experiments don't directly show a biological basis (that would be more related to biological studies like dissections or genetic analysis). Option C is incorrect as "effectiveness" is a more general term and not the primary outcome of a typical experiment; the main goal is to establish cause - and - effect.

Answer:

D. cause and effect.
