Question 2.
Write a short notes on the following.
a) Secondary sexual characters
b) Adam’s Apple.
Answer:
a) Secondary sexual characters:
The characters which are developed at the onset of puberty in both girls and boys are called secondary sexual characters.

Secondary sexual characters in males (boys) : The testes or male reproductive organs secrete sex hormone called testosterone. This testosterone helps in the development of beard, moustache and the low pitch voice. External hair growing under arm pit will be seen. Growth of bones and muscles also seen in the males.

Secondary sexual characters in females (girls) : Ovary of the female reproductive organ secretes sex hormones called estrogen and progesterone. Estrogen helps in the development of uterus, mammary glands and fallopian tubes. It also helps in the growth of hair and high pitch voice.

b) Adam’s Apple: This is actually a partial growth of our voice box or larynx. The Adam’s apple is formed due to elongation of the thyroid cartilage which protrudes out infront of the neck.

This is caused by thyroid stimulated hormone secreted from pituitary gland during adolescence.

As a result of this, muscles attached to the cartilage get loosened and thickened. When air passes through these chords a hoarse sound is produced in males.

• The order and discipline in one’s individual life is the key to avoid any unnecessary or bad habits.

Question 10.
Prepare a three minute speech on behavioural changes in adolescents.
Answer:
The life of man exists with definite stages from birth until the end of life. Adolescence is more complex stage of life that brings vital changes in external and internal parts of the body.

During adolescence behavioural changes also occur very vitally. An adolescent child shows interest to spend time with peers. Children in adolescence do not show interest to discuss the changes with their parents. They face a lot of pressure due to these changes and fail to decide whether they belong to adulthood or childhood. This is the period of confusion the life.

Adolescents take care of their face by applying powder and combing their hair frequently. They show restlessness while their parents suggest to do something. They do not care the suggestions and advice of their parents. Let us see some other unique behavioural activities done by adolescents.

• They show interest towards body and self is natural.
• Attraction towards opposite sex is a normal response. But no need to worry.
• The brain of adolescents is full of jealous acts and urge to find reasons of several things around. They develop abstract ideas as well.
• Emotionally they can define themselves and get new thoughts for their life activities.
• Adolescents behave in a different manner as compared to what they did during childhood with peers and elders.
• They are more independent in nature and very self conscious.
• An adolescent may feel insecure while trying to adjust to the changes in the mind.
• They seek company of friends to share their feelings even if they are opposite sex.

This is just because they need a lot of attention, love and care as well as answer to all their queries regarding their body and its developments. It is the first and the foremost duty for every adult to prepare oneself to reveal to the adolescent, the secrets of nature and the natural course of life as it is.

Question 11.
Nature prepares human body to reproduce her generations. What do you think of it?
Answer:
Reproduction is most important for continuation of human race. We know that reproduction takes place by the fusion of male and female gametes. Adolescents become capable of reproduction when their testes and ovaries begin to produce gametes. In females, the reproductive phase begins around 10 – 12 years of age and lasts till the age of approximately 45 – 50 years.

The ova begins to mature with the onset of adolescence. One ovum matures and is released by one of the ovaries once in about 28 – 30 days. During ovulation the uterine wall becomes thick so as to receive a fertilized egg which leads to pregnancy.

If fertilization does not occur the released egg and thickened lining of the uterus along with its blood vessels are shed off. This causes bleeding in women which is called menstruation. At 45 to 50 years of age, the menstrual cycle stops. Stoppage of menstruation is termed as The above changes in women show nature’s wonderful phenomena.

Question 12.
You know that early marriage is a social taboo. Prepare some slogans to prevent this.
Answer:
Slogans on preventing early marriages.

• “Age 21 for girl – Age 23 for boy is the age for marriage”.
• Early marriage is early end of age.
• Need good health ? Marriage at right age is wealth.
• Get married only after 20.

Question 13.
13 years old Swaroop always thinks of his height. Can he improve his height? What do you suggest him?
Answer:

• I can suggest Swaroop not to worry about his height at the age of 13.
• I educate him about the rate of growth in height varies in different individuals.
• Since he is 13 there may be improvement in his height by the age of 17 or 18.
• Because boys or girls can reach their 100% height by the age of 18.
• Infact some may grow suddenly and then growth slows down gradually.
• I hope that Swaroop can satisfy himself psychologically with the above suggestions.

Question 14.
Are you angry with your parents. How do you wish your parents to be?
Answer:
In fact I don’t want to be angry with my parents. I want my parents to be as a friend, guide, teacher, philosopher and an adviser. Sometimes I struggle psychologically to express my opinions at girls and elders.  I seek a valuable friendly atomosphere from my parents with their suggestions to avoid restlessness. I will be happy to build my life with my parents.

Question 15.
What are your expectations about your parents and teachers ?
Answer:
My expectations from my parents and teachers.

• My parents should understand my problems in adolescence stage.
• Parents & teachers have to allow me to spend time with my friends.
• They have to allow us to think independently in our life.
