A group of students are reviewing information about delayed puberty in preparation for a class discussion. The students demonstrate understanding of this condition when they describe which as occurring in girls?

Breast development has not occurred by age 13

Explanation:

Delayed puberty is a condition under which secondary sexual development which includes breasts in girls, underarm hair and sexual desire in both sexes, etc are delayed. The reason can be varied from family history to medical conditions (for example asthma, kidney diseases, diabetes, etc). One of the treatment of delayed puberty is hormone therapy.

this is a pretty broad question and can be a pretty lengthy answer. since 1900, women have gained a lot more rights and have become active in the workforce. with women being in the workforce, men play a larger role in family life. many family tasks are shared between men and women, whereas, women used to be the sole family caretakers.

that should get you started at least.
