Question 1
1 / -0

Exotic dairy breeds of cattle _________________.

A
Are non-indigenous breeds of cattle

B
Are only found in India

C
Both A and B

D
None of the above

Solution

Explanation: Exotic cattle were first introduced into this region by colonial farmers. Thus, the origin of exotic cattle is generally traced back to Europe. The most common exotic dairy breeds in the region are Friesian, Holstein, Ayrshire, Jersey, Guernsey and Sahiwal. However, the Friesian breed predominates.
Question 2
1 / -0

One of the following shows arrhenotoky in its development

A
Cyana fumea

B
Drosophilia melanogaster

C
Apis mellifera

D
Bonellia viridis

Solution

Arrhenotoky is a form of parthenogenesis in which unfertilized eggs develop into males. It occurs in the members of the insect order Hymenoptera which include bees (Apis mellifera), ants and wasps.
So, the correct answer is option C.
Question 3
1 / -0

Which one of the following SCP organisms lack a membrane bound nucleus?

A
Phycomycetes

B
Chlorella

C
Methanobacillus

D
Spirulina

Solution

Spirulina is a cyanobacterium that are used as a dietary supplement and can be consumed by both animal as well as human. Spirulina lack a membrane bound nucleus. It is a very high source of protein and can help to boost our immune system.
Thus, the correct answer is option D.
Question 4
1 / -0

A piece of plant tissue used in tissue culture is called as ______

A
Explant

B
Somaclone

C
Inoculant

D
Clone

Solution

Plant tissue culture is a technique used to produce clones of plants through micropropagation. The process of tissue culture makes use of various techniques to grow the tissues and plants cells under sterile conditions and nutrient medium. The cells or pieces of tissue that are isolated for the process are called explants.
Question 5
1 / -0

Which of the following two hormones are essential for induced breeding of fishes?

A
TSH and ACTH

B
Oestrogen and progesterone

C
FSH and LH

D
Vassopressin and oxytocin

Solution

Induced breeding of fish is a technique of producing fish by pituitary injecting. it is a widely accepted economical breeding programme in an artificial way. Hormone-induced spawning is the only reliable method to induce reproduction in these fishes. FSH and LH hormones plays a key role in induced breeding in fishes.
Therefore, the correct answer is option C.
Question 6
1 / -0

By using single-cell protein, amount of protein that can be produced by algae grown in ponds (per acre) is

A
20 tons

B
30 tons

C
40 tons

D
50 tons

Solution

A- Single-cell proteins (SCP) are produced by a range of microorganisms and substrate. They are dried cells of microorganism. When SCP is produced, the microbial products produce sufficient proteinaceous substances that can be utilized as protein supplements for animal feeds or human foods. It is estimated that algae grown in ponds can produce 20 tons (dry weight) of protein, per acre, per year.
Question 7
1 / -0

Protein content which is extracted from mixed or pure cultures of yeasts, bacteria, algae and fungi is called

A
Fibrous protein

B
Single cell protein

C
Globular protein

D
Cell protein

Solution
Question 8
1 / -0

One of the limitation for SCP production from alkanes is the

A
Formation of carcinogen

B
Low nutrient content

C
Cannot be given to cattle

D
None of the above

Solution

Single cell protein is the edible unicellular microorganism or the protein rich food extracted from the microorganism for human and animal consumption. Artificially synthesized single cell protein or SCP from alkane is very harmful as it forms carcinogen that affects the health.
Question 9
1 / -0

Single cell production is enabled through

A
Batch operation systems

B
Continuous operation systems

C
Discontinuous operation system

D
Unique operation system
Question 10
1 / -0

SCP is rich in amino acids

A
Lysine

B
Methionine

C
Arginine

D
Both A and B

Solution

Single cell protein is a protein extracted from the pure or mixed culture of organism or cells such as algae, bacteria etc. It is used as a food supplement to humans and animals. It is produced by the microorganism which has 30-70% of protein content in its dry mass. It is a rich source of amino acids like lysine and methionine.
Thus, the correct answer is option D.
