B. sees how the scientist applied the results to the hypothesis.
Gonadotropin-releasing hormone, luteinizing hormone (LH for short) and follicle-stimulating hormone (FSH for short).
EXPLANATION
When your body reaches a certain age, your brain releases a special hormone that starts the changes of puberty. It's called gonadotropin-releasing hormone, or GnRH for short. When this hormone reaches the pituitary gland, it releases two more hormones into the bloodstream: the LH and FSH. Although boys and girls do have these hormones, it depends on their sexual orientation the way these hormones work.

Answer:
The correct answer is:
Includes at least two groups, one of which does not receive the experimental treatment. (B)
Explanation:
A controlled experiment is made up of at least two groups of participants (subjects). One group (the test group) receives the experimental treatment, which can be an intervention or a new drug to be tested etc, and the effect of the treatment on the subjects is measured, while the second group of similar subjects also known as the control group acts as a baseline and do not receive the treatment or intervention. They act as a baseline to ensure that the change observed in the treatment group was brought about as a result of the treatment.
<em>Note that repeating the experiment several times does not ensure accuracy of the result, rather it ensures reliability of the results hence option D is not correct</em>
