Question

hormones directly participate in which of the following?
correct answer(s)

signaling
cellular defense
communication
behavior
reproduction
gene regulation

incorrect answer(s)

Explanation:

Hormones are chemical messengers that directly participate in signaling (e.g., insulin signaling glucose uptake), communication (intercellular via bloodstream), behavior (e.g., cortisol affecting stress behavior), reproduction (e.g., estrogen/progesterone regulating cycles), and gene regulation (steroid hormones binding DNA to alter gene expression). Cellular defense is not a direct role of hormones (it’s mediated by immune molecules like cytokines).

Answer:

signaling, communication, behavior, reproduction, gene regulation
