1. which of the following hormones is secreted from the adrenal medulla?

a. sex hormones
b. estrogen
c. progesterone
d. amino acid hormones

Explanation:

1. Norepinephrine is linked to prolonged aggressive behavior post-conflict; estrogen is a female sex hormone, testosterone drives baseline aggression but not prolonged post-fight state, and homeostasis is not a hormone.
2. Testosterone is the primary male sex hormone that drives mating competitiveness in male animals; estrogen is female-focused, epinephrine is a stress hormone, and pregnancy is not a hormone.
3. Progesterone is specifically responsible for maintaining the uterine environment during pregnancy; epinephrine is a stress hormone, estrogen supports reproductive development but not pregnancy maintenance, testosterone is a male sex hormone.
4. Estrogen (in females of many species) acts as a pheromone-like signal to attract males from long distances; testosterone is male-focused, progesterone is for pregnancy maintenance, and amino acid is not a hormone.
5. The adrenal medulla secretes amino acid-derived hormones like epinephrine and norepinephrine; sex hormones, estrogen, and progesterone are produced by gonads and adrenal cortex, not the medulla.

Answer:

1. B. Norepinephrine
2. C. Testosterone
3. B. Progesterone
4. A. Estrogen
5. D. Amino acid hormones
