Step-by-step explanation:
During puberty, girls undergo several physical changes known as secondary sexual characteristics. These changes include the development and maturation of breasts, broadening of the hips, and the growth of pubic hair. These changes typically start around the age of 10 and are completed by the age of 14.
The development of breast tissue is usually the first visible change during puberty. It involves the growth and maturation of the mammary glands, which results in the enlargement of breast size. This is considered a significant milestone in the physical development of girls.
Another characteristic of puberty in girls is the broadening of the hips. During this time, the pelvis widens to prepare for potential childbirth in the future. This change is influenced by hormonal activity and indicates the onset of sexual maturation.
Pubic hair growth is another sign of puberty in girls. It occurs in the pubic region, starting with fine, sparse hair that gradually becomes thicker and denser. This change is also driven by hormonal fluctuations and is part of the overall development of secondary sexual characteristics.
