Answer
At age 13, girls typically experience significant developmental changes as part of puberty. These include breast development (often one of the first signs), growth of pubic and underarm hair, widening of the hips and pelvis, increased height (growth spurt), development of body curves due to fat redistribution, onset of menstruation (menarche) if it hasn't occurred already, activation of sweat and oil glands leading to possible acne, and emotional changes due to hormonal fluctuations. The exact timing varies among individuals, with some experiencing these changes earlier or later. These transformations prepare the female body for potential reproduction in the future.
