8. What are the secondary characters in girls?

Secondary characteristics are the physical features that develop during puberty in response to hormonal changes. In girls, these secondary  characteristics include:

1.  development: One of the earliest signs of puberty in girls is the development of buds. As puberty progresses, the  continue to grow and mature.

2. Menstruation: Menstruation, or the onset of the menstrual cycle, is a key secondary  characteristic in girls. It typically begins around the age of 12, although the timing can vary.

3. Widening of hips: During puberty, girls often experience a widening of the hips as the pelvic bones expand. This change is associated with preparing the body for potential childbirth.

4. Body hair: Girls develop body hair in various areas, such as the underarms and region, as a result of increased androgen hormones. The growth and distribution of body hair can vary among individuals.

5. Skin changes: Hormonal changes during puberty can lead to changes in skin, including increased oil production and the potential for acne.

6. Changes in body fat distribution: There is an increase in body fat, particularly around the hips and thighs, as part of the normal physiological changes during puberty.

7. Voice changes: While not as pronounced as in boys, girls may experience some changes in their voice pitch during puberty.

It's important to note that the onset and progression of these secondary  characteristics can vary widely among individuals. Puberty generally occurs over several years, and the sequence and timing of these changes are influenced by genetic, environmental, and nutritional factors.
