Question 1
4 / -1

Which one of the following 0.06M aqueous solutions has lowest freezing point?

A
Al₂(SO₄)₃

B
C₆H₁₂O₆

C
KI

D
K₂SO₄

Solution
Question 2
4 / -1

An escalator is moving downwards with a uniform speed 𝑢. A man of mass 𝑚 is running upwards on it at a uniform speed 𝑣. If the height of the escalator is ℎ, the work done by the man is going up the escalator is

A

C

D

Solution
Question 3

Who first conducted the experiments on evolution to prove Biochemical origin of life?

A
Miller and Urey

B
Darwin

C
Lamarck

D
Weismann

Solution

Stanley Miller and Harold Urey tested the first step of the Oparin-Haldane hypothesis by investigating the formation of organic molecules from inorganic compounds. Their 1950s experiment produced a number of organic molecules, including amino acids, that are made and used by living cells to grow and replicate.
Question 4

An analysis of chromosomal DNA using the Southern hybridization technique does not use:

A
Electrophoresis

B
Blotting

C
Autoradiography

D
PCR
Solution
An analysis of chromosomal DNA using the Southern hybridization technique does not use PCR.

E.M Southern(1979) discovered is a hybridization technique known as Southern blotting for the identification of the particular size of DNA from the mixture of other similar molecules. This technique is based on the principle of separation of DNA fragments by gel electrophoresis and identified by labelled probe hybridization. The various steps involved in this technique are:
- Isolation of DNA
- Digestion of DNA by restriction endonucleases
- Separation of DNA fragments by electrophoresis
- Blotting- transferring separated DNA fragments to synthetic membranes, such as nitrocellulose or nylon
- Hybridisation using labelled VNTR probe
- Detection of hybridised DNA fragments by autoradiography.
Question 5
4 / -1

The ratio of the velocity of the sound in hydrogen at the same temperature is:

A

B

C

D

Solution

Velocity of sound in gas,

Where the symbol have their usual meanings, At the same temperature,
Question 6
4 / -1

Which part is supposed to be a vestige of oval aperture?

A
Foramen ovale

B
Fossa ovalis

C
SA node

D
Bundle of His

Solution

The fossa ovalis is a depression in the right atrium of the heart, at the level of the interatrial septum, the wall between the right and left atrium. The fossa ovalis is the remnant of a thin fibrous sheet that covered the foramen ovale during fetal development. It is a vestige of the foramen ovale, and its floor corresponds to the septum premium of the fetal heart.

1-S, 2-P, 3-R, 4-Q

Solution

List-I (Electrode)		List-II (Type)
1.	Calomel	P.	Reference
2.	Glass	Q.	Membrane

Question 8
4 / -1

A particle executes linear simple harmonic motion with an amplitude of 3 cm. When the particle is at 2 cm from the mean position, the magnitude of its velocity is equal to that of its acceleration. Then its time period in seconds is:

A

B

C

D

Solution

Velocity of particle executing S.H.M

x = displacement at any time interval 𝑎 = amplitude = 3 cm
Question 9
4 / -1

Which of the following gates serve as building blocks in digital circuits?

A
OR and AND gates

B
AND and NOT gates

C
OR and NOT gates

D
NAND and NOR gates

Solution

NAND and NOR gates are known as universal gates. Any one of these gates can be used to implement any kind of logic gate. This kind of feasibility does not exist with other gates i.e. any other gate cannot solely implement all logic gates. For example, AND gate cannot be implemented using an OR gate and vice-versa. The implementation of NAND and NOR gates to generate other logic gates is shown above.
Question 10
4 / -1

Which of the following forms the basis of the modern periodic table?

A
Atomic mass

B
Atomic number

C
Number of nucleons

D
All of these

Solution

The periodic table is a tabular arrangement of the chemical elements, ordered by their atomic number (number of protons), electron configurations, and recurring chemical properties. This ordering shows periodic trends, such as elements with similar behavior in the same column.
