The purpose of the study described in the passage was: A. to determine whether LH can modulate GnRH or NPY secretion. B. to determine whether GnRH can modulate NPY secretion. C. to determine whether NPY can modulate LH secretion. D. to determine whether NPY can modulate GnRH secretion.

The correct answer is C) To determine whether NPY can modulate LH secretion.

Explanation:

NPY means Neuropeptide Y while LH means enhances luteinizing hormone.

In the study above, LH is the dependent variable.

Studies have shown that NPY increases LH secretion in part by enhancing the release of LH in response to GnRH. GnRH is an acronym for Gonadotropin-Releasing Hormone.

The above study is a branch of science (Physiology and medicine) which deals with the study of endocrine glands and hormones - Endocrinology.
