Weekly Quiz Competition

Question 1
4 / -1

Inulin found in plant cell is a:

A
Lipid

B
Protein

C
Polysaccharide

D
Vitamin

Solution

Plant hormones, also known as phytohormones, are chemicals that regulate plant growth. Plant hormones are signaling molecules and are produced in plants in very small quantities. Hormones regulate cellular processes in locally targeted cells and when they reach other places in the plant, they regulate cellular processes. Inulin is an unusual polysaccharide and polymer of fructose. It is used as a fructose, particularly in roots and tubers of the family Compositae (e.g. Dahlia tubers).

Hence, the correct option is (C).
Question 2
4 / -1

The increase in the width of the depletion region in a p-n junction diode is due to

A
Reverse bias only

B
Both forward bias and reverse bias

C
Increase in forward current

D
Forward bias only

Solution

The increase in the width of the depletion region is due to the absence of the electrons and holes in the region. This occurs only in the case of the reverse bias only in a diode.

Hence, the correct option is (A).

Question 3

4 / -1

Match the following columns and select the correct option.

Column-I	Column-II
(a) Eosinophils	(i) Immune response
(b) Basophils	(ii) Phagocytosis
(c) Neutrophils	(iii) Release histaminase, destructive enzymes
(d) Lymphocytes	(iv) Release granules containing histamine

(a)-(iii), (b)-(iv), (c)-(ii), (d-(i)

(a)-(iv), (b)-(i), (c)-(ii), (d-(iii)

(a)-(i), (b)-(ii), (c)-(iv), (d-(iii)

(a)-(ii), (b)-(i), (c)-(iii), (d-(iv)

Question 4
4 / -1

A 0.5 m long metal rod PQ completes the circuit as shown in the figure. The area of the circuit is perpendicular to the magnetic field of flux density 0.15 T. If the resistance of the total circuit is 3Ω, calculate the force needed to move the rod in the direction as indicated with a constant speed of 2 m/s.

A
5.78 mN

B
3.75 mN

C
4.95 mN

D
11.25 mN

Solution
Question 5
4 / -1

Which of the following is not correct about carbon monoxide?

A
It forms carboxyhaemoglobin

B
It reduces the oxygen-carrying ability of blood

C
The carboxyhaemoglobin (haemoglobin bound to CO) is less stable than oxyhaemoglobin

D
It is produced due to incomplete combustion
Question 6
4 / -1

Ozonolysis of C₇H₁₄ gives 2 -methyl-3-pentanone. The alkene is:

A
2-ethyl-3-methyl-1-butene

B
2-methyl-3-ethyl-3-butene

C
2,5 -dimethyl -3,4 -diethylhex-3-ene

D
2 -methyl-3-ethyl-1-butene

Solution

The given ketone has the structure

Hence, the correct option is (A).
Question 7
4 / -1

A body is orbiting Earth at a mean radius 9 times as great as the orbit of a geostationary satellite. In how many days will it complete one revolution around Earth and what is its angular velocity?

A
20 days; 2.693 × 10 ^-9 rad/sec

B
23 days; 2.693 × 10 ^-6 rad/sec

C
27 days; 2.693 × 10 ^-6 rad/sec

D
29 days; 2.693 × 10 ^-10 rad/sec

Solution
Question 8
4 / -1

A pendulum bob of mass 50 g is suspended from the ceiling of an elevator. The tension in the string if the elevator goes up with uniform velocity is approximately:

A
0.30 N

B
0.40 N

C
0.42 N

D
0.50 N

Solution

As elevator goes up with uniform velocity then acceleration a=0.

Then, the tension in the string

T=m(g+a)

T=m g

⇒T=5×10⁻³×10

⇒T=0.5 N

Hence, the correct option is (D).
Question 9
4 / -1

Chemically hormones are:

A
Biogenic amines only

B
Proteins, steroids and biogenic amines

C
Proteins only

D
Steroids only

Solution

Hormones are chemical messengers formed by endocrine cells. Chemically hormones are of the following types: Aminescomposed of amino group e.g., Melatonin.

Amino acids - e.g. Thyroxine

Peptides - e.g. Insulin

Insulin Steroids - e.g. Aldosterone

Hence, the correct option is (B).
Question 10
4 / -1

A wire of length L is drawn such that its diameter is reduced to half of its original diameter. If the initial resistance of the wire were 10Ω, its new resistance would be:

A
40Ω

B
80Ω

C
120Ω

D
160Ω
