Que-1: The statistical study of human population is :

1. Population density
2. Population growth
3. Demography
4. Population explosion

Ans: Demography
Hint: Demography is the study of human populations, focusing on things like their size, density, and how people are distributed across different areas.

Que-2: Surgical method of sterilization in women involves cutting and tying of :

1. Ureter
2. Fallopian tube
3. Uterus
4. Urethra

Ans: Fallopian tube
Hint: The surgical method of sterilization in women involves cutting and tying the fallopian tubes so that the eggs cannot travel to the uterus.

Que-3: When the number of individuals added to the population exceeds the number of individuals lost, there is :

1. Decrease in carrying capacity
2. Exponential population growth
3. Zero population growth
4. Decrease in biotic potential

Ans: Exponential population growth
Hint: When more individuals are added to a population than the number that are lost, the population grows rapidly in an exponential manner.

Que-4: The symbol of family welfare is :

1. Red circle
2. Green triangle

Assertion Reason Type Questions on Population

Que-11:

Assertion. Population density is the number of individuals in an area of 100 square kilometers per year.
Reason. Population density gives us an idea of all the living organisms of different species in a particular area every year.

1. Both A and R are True.
2. Both A and R are False.
3. A is True and R is False.
4. A is False and R is True.

Ans: Both A and R are False.
Explain: Population density refers to the number of individuals living in one square kilometer. It gives an idea of the average number of individuals of a species present in a given area.

Que-12:

Assertion. Tubectomy is a temporary method of contraception for males in which the sperm ducts are cut and ligated with a nylon thread.
Reason. Tubectomy closes the passage of the sperms. The sperm duct is also known as vas deferens, which stores the sperms for some days during which they mature and become motile.

1. Both A and R are True.
2. Both A and R are False.
3. A is True and R is False.
4. A is False and R is True.

Ans: Both A and R are False.
Explain: Tubectomy, or female sterilization, is a surgical procedure in which a woman’s fallopian tubes are blocked or sealed to stop eggs from reaching the uterus. It is considered a permanent method of contraception.

Que-13:

Assertion. Fossil fuels are renewable and non-conventional sources of energy.
Reason. The underground reserves of coal and petroleum are depleting fast. People should look at other non-conventional sources of energy like solar energy, tidal energy, etc. for their use.

1. Both A and R are True.
2. Both A and R are False.
3. A is True and R is False.
4. A is False and R is True.

Ans: A is False and R is True.
