Quizplus · Accepted Answer

The development of secondary sexual features, including the growth of pubic and underarm hair, breast development in females, and deepening of the voice in males, signals the onset of puberty. Excessive sweating, loss of skeletal muscle tension, and significant decline in bone mineral density may occur during puberty but are not the primary indicators. The development of external genitalia occurs earlier in life during fetal development.
