2. Which of the following statements is true?

1. The theme of Earth Day 2020 is ‘Climate Action’.
2. The Earth temperature has already reached a 1°C increase.
3. The global warming potential of Nitrogen Oxide is less than carbon dioxide but more than methane.

Select the correct answer from the codes given below:

1. 1,2 and 3
2. 1 and 3 only
3. 1 and 2 only
4. 2 only

Ans. C

Explanation

Earth Day is celebrated annually since 1970 to create awareness against environmental crises. According to the IPCC report, Earth has already reached a 1°C mark of increase in temperature and thus can soon breach the 1.5°C limit of the temperature.

Global Warming Potential shows how much heat does 1 tonne of a particular gas emitted would absorb as compared to the 1 tonne of carbon dioxide emitted. In this case, Nitrogen Oxide has higher Global Warming Potential (265-298 times over 100 years) than methane (28 times over 100 years). Since the comparison is made with Carbon Dioxide it always has a GWP of 1.

Hence, the correct answer is C.

 

3. Which of the following is true about the YUVIKA program?

1. It is under the Ministry of Science and technology.
2. The program aims to create awareness about new science and technology among young persons.
3. Both A and B
4. Neither A nor B

Ans. D

Explanation

YUVIKA program or the Young Scientist Program is under ISRO under the Department of Space and aims to promote awareness among the school students about space and related technologies. The students of class 9^th can be part of this program. Under these 3 students will be selected from each state and UT every year from each state/ UT.

Hence, the correct answer is D.

 

4. Which of the following is true about Thalassemia?

1. It is a genetic disorder.
2. It occurs because the body makes an inadequate amount of hemoglobin.
3. It is a rare disease in India.
4. It can cause Anemia.

Select the correct answer from the codes given below:

1. 1,2 and 3 only
2. 1,2,3 and 4
3. 1,3 and 4
4. 1,2 and 4 only

Ans. B

Explanation

Thalassemia is a genetic blood disorder that occurs when there is an insufficient amount of hemoglobin production in the body. It occurs due to the missing or mutation of alpha or beta protein which assists in the formation of hemoglobin. It can lead to the condition of Anemia. It is a rare disease in India (though there is no standard definition in India).

Hence, the correct answer is B.

 

5. Which of the following is true about Ethanol?

1. It can’t be used in its pure form as a fuel.
2. Using ethanol causes zero-emission of Greenhouse gases.
3. It is considered as non-conventional but non- renewable source of energy

Select the correct answer from the codes given below:

1. 1,2 and 3
2. 1 and 3 only
3. 1 and 2 only
4. None of the above

Ans. D

Explanation

Ethanol or ethyl alcohol is produced from the fermentation of food crop waste like corn, sugarcane or paper waste, etc. The ethanol is used in combination with other fuels like petrol, diesel, etc. and is environment friendly as causes much less emission of the greenhouse gases (not the zero-emission). It can’t be used in pure form due to its high affinity with water, which can cause a problem in the engine and also because it is hard to vaporize due to which there can be problems in starting the vehicle, especially in the winter season.  So some amount of petrol or diesel is recommended to be kept with ethanol. It is classified as a renewable source of energy.

Hence, the correct answer is D.
