ANSWERS TO MCQS

1 C)

FOR YOUR INFORMATION:

– THE Tamil Nadu government has issued orders to conserve Nilgiri tahr through a project. The Rs 25.14 crore project would be carried out over a period of 5 years, from 2022 to 2027, and would employ a strategy including synchronized surveys to estimate the number of tahrs via radio telemetry and radio collars, among others.

— It is called locally Varaiaadu. Statement 4 is therefore correct.

— The tahr was a endangered species and protected by schedule I of the Indian Wildlife Protection Act, 1972. Therefore, statement 1 is not correct and statement 2 is correct.

— The animal is endemic to the Western Ghats, which is internationally recognized as a region of immense global importance due to its biodiversity. Therefore, statement 3 is correct.

— According to a 2015 report from the World Wide Fund for Nature, there are 3,122 Tahrs in the wild.

— The project – the Nilgiri tahr – aims to restore its original habitat and attempt to reintroduce the species to the areas where it originally lived.

Therefore, option (c) is the correct answer.

2.(a)

FOR YOUR INFORMATION:

— Hemochromatosis is genetic, but some can also acquire it through blood transfusions, certain blood problems, liver disease, or excessive alcohol consumption.

— Excessive accumulation of iron in the body — Hemochromatosis –can damage the liver.

— According to doctors, men are more likely to have excess iron buildup in the body because women get rid of extra iron through the blood during menstrual cycles or pregnancy.

— Hemochromatosis can be treated to avoid serious complications. However, if left untreated, hemochromatosis will continue to build up iron in the body.

— Classical hemochromatosis (CHH), a type 1 hemochromatosis, is one of the main causes of iron overload and is quite common. People who suffer from HHC (too much iron) absorb extra iron from their diet. Extra iron cannot be eliminated by the human body.

Therefore, option (a) is the correct answer.

3.(c)

FOR YOUR INFORMATION:

— Rubber products have a wide range of uses, from automobiles to medical devices. Natural rubber is a major raw material for the automotive industry (and is used to make everything from tires to engine parts. Therefore, statement 1 is correct.

— India’s captive consumption of natural rubber is 11 lakh tonnes per year, of which 4 lakh tonnes are imported. Similarly, of the 7 lakh tonnes of synthetic rubber consumed annually in the country, 4 lakh tonnes are imported.

— Natural rubber is imported from countries like Malaysia, Indonesia, Vietnam etc. Statement 2 is therefore correct.

— To protect farmers, the government imposes a 25% import duty on natural rubber, but this has exacerbated our problems.

Therefore, option (c) is the correct answer.

4.(d)

FOR YOUR INFORMATION:

– THE The 2023 Nobel Prize in Chemistry has been awarded to Moungi Bawendi, Louis Brus and Alexei Ekimov For “the discovery and synthesis of quantum dots.

— These smaller components of nanotechnology now beam their light from TVs and LED lights and can also guide surgeons when removing tumor tissue, among other things.

What are quantum dots?

— The properties of any element are determined by the number of electrons it has. However, when matter is extremely small, such as in nanodimensions, its properties are determined by its size. The more electrons are packed into a smaller particle, the more its properties are affected. Quantum dots are particles whose size determines their behavior.

Therefore, option (d) is the correct answer.

5.(b)

FOR YOUR INFORMATION:

— A video of a An endangered white-bellied heron spotted in Kamlang Tiger Reserve in Arunachal Pradesh. Lohit district has surfaced online.
