Options:
A

Nitrosomonas and Klebsiella

B

Rhizobium and Diplococcus

C

Nitrobacter and Azotobacter

Which of the following set of coenzymes are nucleotides of vitamin niacin?

Options:
A NAD, NADP
B FMN, FAD
C ATP, ADP
D ATP, FAD

The correct answer is:
NAD, NADP

Solution:
NAD can be synthesized from simple building-blocks (de novo) from the amino acids tryptophan or aspartic acid. In an alternative fashion, more complex components of the coenzymes are taken up from food as the vitamin called niacin. Similar compounds are released by reactions that break down the structure of NAD. These preformed components then pass through a salvage pathway that recycles them back into the active form. Some NAD is also converted into nicotinamide adenine dinucleotide phosphate (NADP).

Which of the following set of quantum number is correct for an electron in 5f orbital?

Options:
A n=5,l=3,m=+4,s=+12
B n=5,l=4,m=-4,s=-12
C n=5,l=2,m=-1,s=+12
D n=5,l=3,m=+1,s=+12

The correct answer is:
n=5,l=3,m=+1,s=+12

Solution:
Any subâorbit is represented as nl such that n is the principle quantum number (in the form of values) and l is the azimuthal quantum number (its name).

Value of l<n	l	0	1	2	3	4

s	p	d	f	g

Value of m: âl to +l including 0,
Value of s: +12 or -12
for 5f: n = 5, l = 3, m = any value between â3 to +3.
Hence n = 5, l = 3, m = +1, s = +12 is the correct set. In other options these conditions are not satisfied so they are incorrect.

Which of the following set of statements regarding the SN1 reaction shown by alkyl halide is correct here?
1. the SN1 reaction on the chiral starting material end up with racemization of the product
2. The more stable the carbocation intermediate the faster the SN1 reaction
3. the added nucleophile plays no kinetic role in SN1 reaction
4. The SN1 reaction involves the inversion of configuration of the optically active substrate

Options:
A 1, 2
B 2, 3
C 1, 3
D 1, 2, 3

The correct answer is:
1, 2, 3

Solution:
In SN1 reaction, rate of substitution depends on the concentration of substrate only and not upon nucleophile. In case of SN1 reaction there is recemization. SN1 reaction will be faster, if carbocation formed is more stable.

Which of the following set represent the effect of noise pollution on human health?

Options:
A

Sleeplessness, increased heart beat, and altered breathing pattern

B

Sleeplessness, decreased heart beat, and altered breathing pattern

C

Sleeplessness, irritation of respiratory system, and altered breathing pattern

D

Sleeplessness, irritation of respiratory system, and inflammed lungs

The correct answer is:

Sleeplessness, increased heart beat, and altered breathing pattern

Solution:
A brief exposure to extremely high sound level (150 dB or more), generated by take-off of a jet plane or rocket, may damage eardrums thus permanently impairing hearing ability. Even chronic exposure to a relatively lower noise level of cities may permanently damage the hearing abilities of humans. Noise also causes sleeplessness, increased heart beat, altered breathing patterns, thus considerably stressing humans.

Which of the following sets of characteristics is found in phylum Echinodermata?

Options:
A Presence of water vascular system and indirect development of larvae
B Bilaterally symmetrical and acoelomate
C Reproduction is asexual and fertilisation is internal
D Presence of water vascular system with a well-developed excretory system

The correct answer is:
Presence of water vascular system and indirect development of larvae

Solution:
Adult echinoderms are radially symmetrical, while their larvae is bilaterally symmetrical. They are triploblastic and coelomate organisms. The most distinctive feature of echinoderms is the presence of water vascular system which helps in locomotion, capture and transport of food and respiration. An excretory system is absent. Sexes are separate. Reproduction is sexual. Fertilisation is usually external. Development is indirect with free-swimming larvae.

Which of the following sets of diseases is caused by bacteria?

Options:
A Cholera and tetanus
B Typhoid and smallpox
C Tetanus and mumps
D Herpes and influenza

The correct answer is:
Cholera and tetanus

Solution:
Cholera is caused by the bacterium Vibrio cholera and tetanus is caused by the bacterium Clostridium tetani.

Cholera is an acute diarrheal illness caused by infection of the intestine with Vibrio cholerae bacteria. People can get sick when they swallow food or water contaminated with cholera bacteria. The infection is often mild or without symptoms, but can sometimes be severe and life-threatening.

Tetanus is a serious disease of the nervous system caused by a toxin-producing bacterium. The disease causes muscle contractions, particularly of your jaw and neck muscles. Tetanus is commonly known as lockjaw. Severe complications of tetanus can be life-threatening.

Smallpox, mumps, herpes, and influenza are viral diseases.

Which of the following sets of inner ear parts comprises of hair cells?

Options:
A organ of corti and vestibular apparatus
B crista ampullaris and organ of corti
C macula and organ of corti

Which of the following sexually transmitted diseases is not completely curable?

Options:
A Gonorrhoea
B Genital warts
C Genital herpes
D Chlamydiasis

The correct answer is:
Genital herpes

Solution:
Herpes simplex type 1 or 2 viruses causes genital herpes, an infection of the skin and mucous membranes in the genital and surrounding areas. Herpes simplex virus usually spreads, when in contact with blisters. However, people with genital herpes can shed the virus from the genital area and infect others even without a blister being present. Cold sores on the mouth are a potential source of genital infection during mouth-to-genital contact. Medications can help decrease the severity of the herpes lesions and prevent recurrences, but they do not cure the infection.

Which of the following shape are not possible for possible value of 'n' in XeFn molecule?

Options:
A Linear
B Square planar
C Trigonal planar
D Capped octahedral

The correct answer is:
Trigonal planar

Solution:
In XeFn , the possible values of 'n' is 2, 4, 6, then compound should be XeF2 (sp3d linear), XeF4 ( sp3d2 square planar) XeF6 ( sp3d3 capped octahedral) so in this case trigonal planar molecule is not possible.

Which of the following shapes of SF4 is more stable and why?

Options:
A (i), due to 3 lp-bp repulsion at 90°
B (ii), due to 2 lp-bp repulsion
C Both are equally stable due to 2 lp-bp repulsions
D Both are unstable since SF4 has tetrahedral shape

The correct answer is:
(ii), due to 2 lp-bp repulsion

Solution:
The structure (ii) is more correct as in lone pair of electrons are assigned at equatorial position which means electronic repulsion will be less here so it will be more stable also. In case of trigonal pyramidal geometry lone pairs are place at equatorial positions.
