1. Which of the following is true about Agappe Chitra Magna?

1. It is a paper-based test kit developed by ICMR to detect the COVID-19 virus.
2. It is a test kit to measure the level of toxicity in the water.
3. It is a test kit for the presence of adulterated material in the food.
4. It is a nanoparticle-based test kit to detect the presence of COVID-19 virus in the body.

Ans. D

Explanation

Agappe Chitra Magna is a magnetic nanoparticle-based test kit to extract the viral RNA from the body and thus detecting the presence of COVID-19 virus in the body.

RNA extraction kit was developed by Sree Chitra Tirunal Institute for Medical Sciences and Technology (SCTIMST), Trivandrum, an Institute of National Importance of the Department of Science and Technology (DST) along with Agappe Diagnostics Ltd. This will make India self- sufficient in the availability of the test detection kits.

Hence, the correct answer is D.

 

2. Which of the following are the possible applications of Coir Geo textile?

1. Promoting quick vegetation
2. Avoiding soil erosion
3. Keep the topsoil filled with moisture
4. As a sealing material
5. To stabilize the layer of landfills
6. As a replacement of wood in construction
7. As sunscreens

Select the correct answer from the codes given below:

1. 1,2,3,4 and 5
2. 2,3,4 and 5
3. 1,4,5,6 and 7
4. 1,2,3,4,5,6 and 7

Ans. D

Explanation

Coir geo textile is a natural fiber extracted from the outer husk of the fruit of the coconut tree. It is a renewable, recyclable, biodegradable fiber that is strong, resistant from being rotten. It needs no chemical treatment.

It helps in preventing soil erosion, allowing vegetation to flourish. It absorbs the water and thus provides continuous moisture to the topsoil. In this way, it promotes quick vegetation. It can also be used as a sealing material.

It helps in stabilization of landfill by effectively separating the landfill from the stone-based course. Coir, when mixed with phenol-formaldehyde resin and converted into boards, provides as a low-cost substitute to wood. Because of its adjustable property, it is also used as sunscreen and windscreen.

Hence, the correct answer is D.

 

3. Recently a loud sound was heard all over Bengaluru, which is also called the Bengaluru boom and is expected to be a sonic boom. With respect to this, consider the following statements:

1. Sonic Boom is created when an object travels at hypersonic speed.
2. A hypersonic boom can create two booms one when overpressure is created and others at the time of pressure returns to normal.
3. Both statements are true.
4. None of the statements is true.

Ans. C

Explanation

A sonic boom is the effect of hypersonic waves produced by an object moving at hypersonic speed. A jet flying at hypersonic speed creates overpressure before the plane and creates negative pressure behind the jet. The person who comes in contact of the direction of the waves feels the effect of the waves and thus hears the sound. Through a hypersonic jet, two booms are created; one is in case of overpressure and other when sonic pressure returns to normal.

Hence, the correct answer is C.

 

4. Recently scientists at Pune based Agharkar Research Institute (ARI) have mapped the alternative dwarfing genes of wheat, i.e Rht14 and Rht18. Which of the following correctly describes its advantages?

1. The genes, when used, will reduce the rice stubble burning.
2. It reduces the water requirement for irrigation.
3. The genes would allow the crops to be grown in a short period.
4. The new wheat crop reduces the need for fertilizers.

Select the correct answer from the codes given below:

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

Ans.  B

Explanation

Scientists at Pune based Agharkar Research Institute (ARI) have mapped the alternative dwarfing genes of wheat, i.e Rht14 and Rht18, on chromosome 6A in durum wheat.

These genes being discovered will help to reduce the burning of rice stubble as the wheat crop have these genes that can be grown on the land that have rice stubble. Also, seeds being sown are sown deep so that they can use the soil moisture and reduce the need for one round of irrigation.

Hence, the correct answer is B.
