Weekly Quiz Competition

Question 1
1 / -0

Lactation in sterile cows is induced by giving

A
Stilbestrol

B
Gonadotropin

C
Vitamin B2

D
None of the above

Solution

Majority of Indian cattle have been on marginal inputs and are infertile and poor milk yielders. Stilbestrol tablets are implanted to induce lactation in sterile cows and immature females. Stilbestrol is a synthetic nonsteroidal estrogen.
Therefore, the correct answer is option A.
Question 2
1 / -0

Exchange of germplasm is carried mostly through shoot tips because it is

A
Cheap

B
Small and handy

C
Virus-free

D
Genetically stable
Solution
- The shoot tip is a virus-free part of the plant and it is because of the presence of meristematic cells in the shoot tip.
- These cells are actively dividing and help in the apical dominance of the plant as well as the increase of height of the plant as a combined effect of auxin.
- Meristematic cells are able to multiply at a very rapid rate compared to the multiplication of viruses. This enables the shoot tips as virus-free regions.
- So, the correct answer is option C.
Question 3
1 / -0

Who was first to develop artificial skin by tissue culture

A
Harrison

B
Carrel

C
Maximov

D
Engene-Bell

Solution

Eugene Bell, Emeritus Professor of Biology at Massachusetts Institute of Technology (MIT), was the founding father of the science of tissue engineering was the first to develop artificial skin by tissue culture.
So, the correct option is D.
Question 4
1 / -0

Murashige and Skoog medium is used for

A
Isolation of fungal strains

B
Culture of bacteria

C
Raising plants through micropropagation

D
Culture of protein rich cyanobacterium Spirulina

Solution

Plants obtain minerals from the soil. Hence, they can be grown in a soil less nutrient medium. Various nutrient media are also used to culture plant through micropropagation. Because plant cells are totipotent, hence they can be propagated through micropropagation.
Micropropagation is a technique used in plant tissue culture in which a small plant tissue (called as explant) of a plant can be used to obtain multiple new plants, i.e., propagate the mother plant.
Murashige and Skoog medium or (MS Medium) is a plant growth medium used in the laboratories for the cultivation of the plant in cell culture.
So, the correct answer is 'Raising plants through micropropagation'
Question 5
1 / -0

Which is more suitable for germplasm collection?

A
Centre of production

B
Homelands

C
Tropical areas

D
Temperate areas

Solution

The collection of plants or seeds having diverse alleles of all the genes of a crop is known as germplasm collection. It is an example of ex-situ conservation of biodiversity. Germplasm is found in large numbers and in its native form in its homeland.
Thus, the correct answer is option B.
Question 6
1 / -0

In bee colony, all larvae are fed by workers for first two days on

A
Honey

B
Pollen

C
Royal jelly

D
Saliva

Solution

In a bee colony, all bee larvae are fed some royal jelly (a protein-rich secretion from glands on the heads of young workers) for the first few days after hatching but only queen larvae are fed on it exclusively. As a result of the difference in diet, the queen will develop into a sexually mature female, unlike the worker bees. Hence, option C is correct.
Question 7
1 / -0

State whether the following statement is true or false.
Ability of an organism to resist disease is called as host resistance.

A
True

B
False

C
Ambigous

D
Data insufficient

Solution

Ability of an organism to resist disease is called host resistance. These plant varieties are developed under Integrated Pest Management to provide resistance against a particular variety of pest.
Example Bt Cotton a transgenic plant which has resistance to a certain kind of disease called the boll disease.
So, the given statement is true.
Question 8
1 / -0

The ideal floor space required for a layer bird is about

A
0.25 to 0.30 sq.m

B
3 to 4 sq.m

C
10 sq.m

D
4 to 5 sq.m

Solution

Egg-production birds usually spend their entire lives in cages. Although some broiler breeders are similarly housed, most are reared on litter floors. The ideal floor space requirement is very important which is about 15-20 inches which are 0.25 -0.30 sq.m. Although decisions must be made about optimal floor space and feeding and watering requirements based on advice from equipment manufacturers, primary breeders, careful observation, and past experience as to productivity.
Therefore, the correct answer is option A.
Question 9
1 / -0

Which of the following is the sequence of cultivation of fish?

A
Fry --- Fingerlings --- Spawn --- Adult

B
Spawn --- Fry --- Fingerlings --- Adult

C
Adult --- Spawn --- Fingerlings --- Fry

D
Fingerlings --- Fry --- Spawn --- Adult

Solution

Juvenile fish go through various stages between birth and adulthood. They start as eggs which hatch into larvae. Spawning is when adult fish breed and lay their eggs. A spawning pond is a pond where fish can breed and lay eggs. The spawning pond is also where the eggs will hatch into fish fry. The larvae are not able to feed themselves, and carry a yolk-sac which provides their nutrition. Before the yolk-sac completely disappears, the tiny fish must become capable of feeding themselves. When they have developed to the point where they are capable of feeding themselves, the fish are called as fry. When, in addition, they have developed scales and working fins, the transition to a juvenile fish is complete and it is called as a fingerling. Fingerlings are typically about the size of fingers. The juvenile stage lasts until the fish is fully grown, sexually mature and interacting with other adult fish.
Question 10
1 / -0

Which of the following nutrients are added to improve fish culture?

A
NO$$_{3}^{-}$$ and SO$$_{4}^{2-}$$

B
PO$$_{4}^{3-}$$ and NO$$_{3}^{-}$$

C
SO$$_{4}^{2-}$$ and I$$_2$$

D
Both A and B

Solution

Fish culture is the artificial propagation and breeding of fish. Worldwide, the most important fish species used in fish farming are carp, salmon and catfish. Fish culture is improved by super phosphates, ammonium nitrate and ammonium sulphate.
Therefore, the correct answer is option D.
