Answer:
Hypothalamus
Explanation:
Most of these behaviors are related to a person's hormones. Hormones are influenced by the Hypothalamus. This is a tiny part at the base of the brain close to the pituitary gland. The hypothalamus is in charge of releasing hormones, regulating body temperatures, controlling appetite, sexual behavior, and regulating emotional responses. Which falls in perfectly with all the behaviors in the question.
