Q5. This technology is currently taking the digital art and collectibles world by storm. Digital artists are seeing their lives change thanks to huge sales to a new crypto-audience. And celebrities are joining in as they spot a new opportunity to connect with fans. But digital art is only one way to use this technology. They can be used to represent ownership of any unique asset, like a deed for an item in the digital or physical realm. We can use it to represent ownership of unique items. They let us tokenize things like art, collectibles, even real estate. They can only have one official owner at a time.

Q6. Which of the following is/are the characteristics of Semiconductors?
- Formed due to ionic bonding
- Positive temperature coefficient
- Only four valence electrons are in the outermost orbit.
Select the correct answers using the code given below:
(a) 3 only
(b) 1 only
(c) 1 and 3 only
(d) 1, 2 and 3
Correct answer: (a)
Explanation: Semiconductors are materials which have a conductivity between conductors (generally metals) and nonconductors or insulators (such as most ceramics). Semiconductors can be pure elements, such as silicon or germanium, or compounds, such as gallium arsenide or cadmium selenide. They are also known as integrated circuits or, more commonly just chips. They may be the tiniest yet most exacting product ever manufactured on a global scale.
They have four valence electrons in their outermost orbit and are formed due to covalent bonding.
- Conductors are formed using metallic bonding, and insulators are formed using ionic bonding.
The valence and conduction bands in a semiconductor are separated by a forbidden energy gap of 1.1eV.
Resistance is high in semiconductors, whereas it is very small in conductors and very high in insulators.
Semiconductors have negative temperature coefficients (conductors - positive and insulators - negative). Hence, option (a) is correct.
Q7. Which of the following wetlands of India are in the Montreux record?
- Keoladeo National Park, Rajasthan.
- Loktak Lake, Manipur.
- Hirakud Reservoir, Odisha.
- Ansupa Lake, Odisha.
Select the correct answer using the code given below:
(a) 1, 2 and 3 only
(b) 3 and 4 only
(c) 1 and 2 only
(d) 1, 2, 3 and 4
Correct answer: (c)
Explanation:
Currently, two wetlands of India are in Montreux record:
1) Keoladeo National Park (Rajasthan) and
2) Loktak Lake (Manipur).
Chilka lake (Odisha)was placed in the record but was later removed from it.
Q8. With reference to Gravitational Waves, consider the following statements:
- Gravitational waves are produced only when two black holes merge into each other.
- They travel at the speed of light.
Which of the statements given above is/are correct?
(a) 1 only
(b) 2 only
(c) Both 1 and 2
(d) Neither 1 nor 2
Correct answer: (b)
Explanation:
Statement 1 is incorrect: Gravitational Waves are invisible ripples that form when:
- A star explodes in a supernova.
- Two big stars orbit each other.
- Two black holes merge. Hence, statement 1 is not correct.
Statement 2 is correct: They travel at the speed of light and squeeze and stretch anything in their path. As a gravitational wave travels through space-time, it causes it to stretch in one direction and compresses in the other. Any object occupying that space-time region also stretches and compresses as the wave passes over them, though very slightly, which can only be detected by specialized devices like LIGO.
Q9. What is the application of Somatic Cell Nuclear Transfer Technology?
(a) Production of biolarvicides
(b) Manufacture of biodegradable plastics
(c) Reproductive cloning of animals
(d) Production of organisms free of diseases
Correct answer: (c)
Explanation:
In genetics and developmental biology, somatic cell nuclear transfer (SCNT) is a laboratory strategy for creating a viable embryo from a body cell and an egg cell. The technique consists of taking an enucleated oocyte (egg cell) and implanting a donor nucleus from a somatic (body) cell.

Which of the statements given above are incorrect?
(a) 2 and 3 only
(b) 2 only
(c) 1 and 3 only
(d) 1, 2 and 3
Correct answer: (a)
Explanation:
Statement 2 is incorrect: It is a Schedule II animal in the Wildlife Protection Act 1972.
Statement 3 is incorrect: They are currently listed as endangered species by the IUCN Red List of Threatened Species.

Q14. Priya consumes x kg of wheat in a month of 30 days. If she starts using 20% more each day, how many days will wheat last?
(a) 30 days
(b) 24 days
(c) 25 days
(d) Can't determine
Correct answer: (c)
Explanation:
Let the total amount of wheat be 300kg
30 days average - 10kg/day
20% extra use means daily consumption will be 12 kgs
So, total amount of wheat / daily new consumption, i.e. 300/12 = 25 Days.
Q15. A and B are two alloys of Argentum and Brass prepared by mixing metals in proportions 7 : 2 and 7 : 11, respectively. If equal quantities of the two alloys are melted to form a third alloy C, the proportion of Argentum and Brass in C will be?
(a) 7:5
(b) 5:7
(c) 9:5
(d) 5:9
Correct answer: (a)
Explanation: The first alloy is prepared by mixing metals in proportions 7 : 2,
Then the weight of the first alloy will be = 7x + 2x
Assume ‘x’ = 1Kg
The weight of the first alloy will be 9kg
The second alloy is prepared by mixing metals in proportions 7 : 11,
The weight of the second alloy will be 18kg
If equal quantities of the two alloys are melted to form a third alloy,
Then 18Kg of first alloy should be used, then its ratio will become 14 : 4,
Now, the proportion of Argentum and Brass in third alloy = 7 + 14 : 11 + 4 = 21 : 15 = 7:5
