Question 1
4 / -1

A uniform rod of length l is free to rotate in a vertical plane about a fixed horizontal axis through O. The rod is allowed to rotate from rest from its unstable vertical position. Then the angular velocity of the rod when it has turned through an angle θ is –

A

B

C

D

Solution

As given, a uniform rod of length l is free to rotate about an end to the rod with angular velocity ω and the rod has turned through an angle θ.
Question 2
4 / -1

The product butyric acid is obtained from which of the following bacteria?

A
Aspergillus Niger

B
Clostridium bretylium

C
Acetobacter aceti

D
Penicillium

Solution

Clostridium bretylium (bacterium) produces Butyric acid used for making rancid butter.

Butyric acid is biologically produced by Clostridium species and like other acids (acetic acid, lactic acid, propionic acid), it is toxic to the bacteria after a certain concentration. Hence, the product titres are generally low which makes downstream expensive. In order to reduce these costs, in situ removal of butyric acid can be developed. In situ removal strategies are not yet industrially applied for butyric acid, but it is a key area where progress has to be made to make the process economically sustainable.

Hence, the correct option is (B).
Question 3
4 / -1

Which of the following structures temporarily stores sperms?

A
Vas deferens

B
Epididymis

C
Vasa efferentia

D
Urinary bladder

Solution

Sperm are produced in tightly coiled tubes inside of the testes called seminiferous tubules. The epididymis temporarily stores mature sperm cells. Each sperm cell has a flagellum for locomotion or movement. A tube called the vas deferens passes from each epididymis into the body.

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

A star initially has 10⁴⁰ deuterons. It produces energy through the processes

If the average power radiated by the star is 10¹⁶W, the deuteron supply of the star is exhausted in a time of the order of

A
10⁶

B
10⁸

C
10¹²

D
10¹⁶

Solution
Question 5
4 / -1

The product formed in the following chemical reaction is:

A

B

C

D

Solution

NaBH₄ is a reducing agent. If reduces carbonyl group into alcohols but does not reduce esters.

Hence, the correct option is (A).

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

Question 7
4 / -1

Which of the following sets represents selectable markers for Escherichia coli?

A
Chloramphenicol, ampicillin, ranitidine

B
Tetracycline, ranitidine, cimetidine

C
Ampicillin, chloramphenicol, tetracycline

D
Chloramphenicol, streptomycin, kanamycin

Solution

Normally the genes encoding resistance to antibiotics such as ampicillin, chloramphenicol, tetracycline, or kanamycin, etc., are considered useful selectable markers for Escherichia coli.

A selectable marker is a gene introduced into a cell, especially a bacterium or to cells in culture, that confers a trait suitable for artificial selection. They are a type of reporter gene used in laboratory microbiology, molecular biology, and genetic engineering to indicate the success of transfection or other procedure meant to introduce foreign DNA into a cell. Selectable markers are often antibiotic resistance genes.

Hence, the correct option is (C).
Question 8
4 / -1

The transgenic animals are those which have:

A
foreign RNA in all its cells

B
foreign DNA in some of its cells

C
foreign DNA in all its cells

D
Both (A) and (B)

Solution

Transgenic organism is one that has become transformed following the introduction of novel genes into its genome. It is most frequently achieved by integration of cloned DNA sequences following their injection into the fertilised egg. This fertilised egg divides mitotically to form the whole organism so that all the cells of the organism will carry the transferred genes. The transferred genes are known as transgenes.

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

Which of the following hormones is not secreted by anterior lobe of pituitary?

A
Growth hormone

B
Follicle stimulating hormone

C
Oxytocin

D
Adrenocorticotropic hormone

Solution

The pituitary glands are made of the anterior lobe and posterior lobe. The anterior lobe produces and releases hormones while the hormones are not produced by posterior pituitary. All the hormones such as growth hormone, FSH and adrenocorticotropic hormone are secreted from the anterior lobe of pituitary but oxytocin is secreted from the posterior pituitary.

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

Elimination reaction of 2-Bromo-pentane to form pent-2-ene is:

(a) β-Elimination reaction

(b) Follows Zaitsev rule

(c) Dehydrohalogenation reaction

(d) Dehydration reaction

A
(a), (b), (c)

B
(a), (c), (d)

C
(b), (c), (d)

D
(a), (b), (d)
