Answer 1

Hint: Adolescence is the stage that links childhood to adulthood. It is the period during which the onset of puberty occurs. This change occurs mainly due to hormonal changes in the body. This is a very vulnerable stage both for boys and girls, therefore, they should pay extra attention to their health.

Complete step by step answer:
(a) During the adolescent stage, a whole growth of the body is occurring due to hormonal changes and hence one requires a proper diet.
So, option (ii) is correct.
(b) The reproductive stage in the women is the duration from menarche to menopause.
Menarche is the beginning of menstruation and it occurs at the age of 12-13 years and menopause refers to the end of the menstrual cycle. It generally occurs at the age of 50 years. Menstruation is the vaginal bleeding which occurs every month if the egg released from the ovary is not fertilised by the sperm. The part of the uterus breaks down and bleeding starts through the vagina. it lasts for days. If fertilisation occurs (that means if pregnancy occurs), then there is no menstruation for the next 9 months.
So, the correct answer is option (i).
(c) The right meal for adolescence or any other age group is a balanced diet that consists of an adequate amount of all nutrients like protein, vitamins, carbohydrates, minerals, roughage (present in green vegetables). Junk food like pizza, burger, lack a balanced diet they only contain carbohydrates and bad fat.
So, the correct answer is option (ii).

Note: Secondary sexual characters in males and females at the age of puberty occurs due to certain hormones like testosterone in males and estrogen in females. It is a time in life when a boy or a girl becomes sexually mature.
