Group A (Very Short Answer Questions)
Answer: Sterile is a condition of materials being fully free from microorganisms such as bacteria, viruses, etc.
Q. When will be the population of a country be doubled if the present annual population growth rate is 1.35%?
Solution:
Given,
Population Growth Rate (PGR) = 1.35%
Now,
Population Doubling Time = $\frac{70}{PGR}$
= $\frac{70}{1.35}$
= 51.85
Hence, the population of the country will be doubled with the PGR 1.35% in 52 years.
Q. Define fecundity.
Answer: Fecundity is the biological ability of either male or female to participate in reproduction.
Q. What is the full form of BCN?
Answer: The full form of BCN is Birds Conservation Network.
Q. Mention the formula to calculate the PGR.
Answer: The formula to calculate the PGR is:
$\dfrac{CBR-CDR+NMR}{1000}*100$
Here,
CBR = Crude Birth Rate
CDR = Crude Death Rate
NMR = Net Migration Rate
Q. What is the name of bacteria that causes stomach cancer.
Answer: The name of the bacteria that causes stomach cancer is Helicobacter pylori.
Q. What is the artificial factor of population change?
Answer: The artificial factor of population change is migration.
Q. What do you mean by Ectopic pregnancy?
Answer: Ectopic pregnancy is a special case of pregnancy where the foetus develops outside the uterus, usually in the fallopian tube.
Group B (Short Answer Questions)
Q. List down the various aspects of Health, Population and Environment and explain any one.
Answer: Health, Population and Environment are interrelated to each other through various aspects. Such aspects are present all around us. Some of those aspects are:
- Physical Aspects
- Biological Aspects
- Socio-cultural Aspects
- Economic Aspects
- Science and Technological Aspects
- Political Aspect
- Psychological Aspects
The basic aspect out of all is physical aspects.
Physical Aspects:
Physical Aspects cover all the man-made as well as natural structures and conditions present in the environment. Natural physical aspects include sun, soil, water, etc. Man-made physical aspects include roads, buildings, bridges, taps, and many more.
The quality of health of people of a certain place is defined by the abundance of prosperous physical aspects present there. Even the people (population) prefer to live in such places. Hence, this ultimately proves that the more we invest in physical aspects, the better health standards we can achieve. Such resources are later enjoyed by the existing population of that place. But, the environment has to be maintained well to maintain the quality of those facilities and structures. Hence, health, population and environment are interrelated to each other.
Q. Briefly describe the cervical mucus method of contraception.
Answer: Cervical mucus method of contraception is a natural conceptive method for women in which the colour, texture and thickness of the cervical mucus determined the safe and unsafe period for having sexual intercourse.
Immediately after menstruation, the cervix has a thick plug around itself. As the level of oestrogen rises, the cervix releases thick, non-slippery, non-sticky and transparent mucus. Sooner, during ovulation, the cervix secrets thin, translucent, slippery and non-breakable mucus. This period is considered as unsafe.
Hence, if the mucus obtained is thick and non-sticky, it is safe for copulation but if the mucus obtained is thin and sticky, then the period is unsafe for copulation.
In conclusion, the cervical mucus test method is only for female. In this, the female tests the mucus secreted by the cervix herself. Depending on above-mentioned factors, copulation is avoided to avoid conception in unsafe period and couples can freely perform copulation in safe period with no risk of conception.
Q. Describe the role of health and sanitation for quality of life.
Answer: Quality of life is the condition of life where all the needs of a family are fulfilled and they enjoy every moments of their life.
Health and sanitation are the important elements for maintaining quality of life because they ultimately protect us from diseases and keep our body fit and fine.
Sound health condition is a basic requirement of every human beings. One can only perform other activities of s/he has proper and sound health condition. "Health is wealth." clearly states the important of health. Having a fit body helps us to earn income, increase savings, eat balanced diet, increase security and much more.
In other hand, sanitation is nowhere less important than a health body. Sanitation is what keeps everything around us safe to touch, eat and use. Without proper sanitation, our body constantly falls ill and we may not feel happy. If we don't, we cannot live a quality of life.
Hence, all health habits and sanitation help to fulfill all other elements of quality of life.
Q."Diarrhoea is a common disease of Nepalese children." Justify this statement.
Answer: "Diarrhoea is a common disease of Nepalese children." This is undoubtedly a true statement based on the fact that Nepalese children are carefree and love to play in the mud, dirt and maintain poor hygiene.
The above statement might be offensive for someone but that is the reality. Diarrhoea is a communicable disease caused by E-coli, Bacillus, etc. This is a condition of passing loose, liquid and watery stool more than 3 times a day. It is easily caused if not maintained proper hygiene.
The children of Nepal love to play in the playgrounds and cover themselves with mud. Also, they find it very interesting to get wet in the rain. As they do so, they are carrying many germs, viruses, bacterias and other microorganisms in their body. On returning home, they do not even bath properly. And, when they eat their food the germs enter their bodies.
Similarly, poor diet is another reason due to poverty. I have encountered various children who are let carefree by their parents and they go around, play in the mud and sometimes even eat it. Due to the poor hygiene condition, poor sanitation, lifestyle, lack of nutritious diet and improper washing of hands, Nepalese children are more prone to such water-borne communicable diseases.
Hence, I stay with the above mentioned statement.
Q. The mid-year population of any one district of Nepal is 150000 is 2058 BS. In same year, 1000 people died, 1500 people came to there for settlement and 500 people moved to other place. Now, find out CDR and GMR.
Solution:
Given,
In 2058 BS,
Mid year population of a place (P) = 150000
Total deaths (D) = 1000
In-migrants (I) = 1500
Out-migrants (O) = 500
Now,
CDR (Crude Death Rate) = $\frac{D}{P}$ *1000
= $\frac{1000}{150000}$ * 1000
= 6.67
Therefore, the CDR of that place in 2058 BS was 6.67 per 1000 mid-year population.
And,
GMR (Gross Migration Rate) = $\frac{I+O}{P}$ *1000
= $\frac{1500+500}{150000}$*1000
= 13.34
Therefore, the GMR of that place in 2058 BS was 13.34 per 1000 mid-year population.
Group C (Long Answer Questions)
Q. Write differences between:
1. Demographic components and processes
2. Natural and artificial contraceptive methods
Answer:
Differences between demographic components and processes are as follows:
| Demographic components | Demographic processes |
|---|---|
| The factors that bring change in the population of a given place over time are called demographic components. | The actual processes that birng change in the population of a given place over time are called demographic processes. |
| Birth, death and migration are the major demographic components. | Fertility, mortality and migration are the major demographic processes. |
Differences between natural and artificial contraceptive devices are as follows:
| Natural contraceptive methods | Artificial contraceptive methods |
|---|---|
| Natural contraceptive methods are those methods of avoiding conception by the proper study of menstrual cycle. | Artificial contraceptive methods are those methods of avoiding conception using artificial devices, chemicals or injections. |
| Natural methods are only temporary. | Artificial methods are temporary as well as permanent. |
| These methods include Calender method, Basal body temperature method, etc. | These methods include use of Oral pills, Diaphragm, etc. |
Q. Make a list of contraceptive methods. Explain in brief about natural contraceptive methods.
Answer: Contraceptive methods are the ways of avoiding conception by either avoiding sexual intercourse or keeping a barrier between male and female secreted hormones.
Here is a list of contraceptive methods:
1. Natural methods:
- Calender method
- Basal Body Temperature Method
- Cervical Mucus Test method
- Withdrawal method
- Lactational Amenorrhea Method
2. Artificial methods:
- Physical method (eg.diaphragm)
- Chemical method (eg. oral pills)
- Injectable method (eg. norplants)
- Permanent method (eg. minilap)
Natural Contraceptive Methods:
Natural contraceptive methods are those ways of avoiding conception either by avoiding the contact between semen and ovum or by avoiding intercourse during unsafe period. There are five common methods of avoiding conception without using any artificial devices or means. In some of these processes, intercourse is avoided during unsafe period (usually known by using methods like rhythm method, cervical mucus test method or basal body temperature method). Also, the ejaculation by men is done outside out of the female body in withdrawal method. In lactational amenorrhea method, women can avoid their menstrual cycle to 6-18 months if they breast feed their offsprings for at least 8 times a day continuously for 20 minutes.
In this way, without using Artificial devices or chemical injections or pills, couples can avoid pregnancy naturally.
Q. Define infant and children. What kind of role would you like to play for management of growing population.
Answer: Infants are babies who are less than 1 year, also termed as zero age babies.
Children is the stage of life in between infancy and puberty.
Growing population is a serious threat to the major developing as well as developing countries around the globe. A country with a PGR of more than 2% and TFR of more than 2 is said to have rapidly growing population. Each and every, one of us has to play an important role for management of growing population. Here are the files that I would play for the sake of population management:
- I would marry at appropriate age when I will be mentally, physically, physiologically, emotionally, and economically mature to maintain a family.
- I would share the information that I have with my friends and my offsprings in order to play a role for awareness regarding population education.
- I would empower the women by creating several job opportunities, educational opportunities and by teaching them their rights, duties and responsibilities.
- I would maintain balance in my family. As an educated citizen, I would always listen to my wife's opinion and never make any one-sided decision.
- I would also maintain proper birth spacing of 4 years of age and only have a maximum of 2 children in my family.
With above mentioned plans, I would help control the population growth by generating awareness and implementing what I have learnt from population education.
