Weekly Quiz Competition

Question 1
1 / -0

Which one of the following cannot be suggested as advantages of SCP?

A
Largely meet protein requirement of human

B
Many enzymes, bioactive molecules etc can be harnessed industrially

C
Do not require special culture media

D
Reduces environmental pollution

Solution

The full form of SCP is single cell protein. It is an edible unicellular microorganism. It is obtained from pure or mixed cultures of algae, yeasts, fungi or bacteria. It contains very high amount of protein in it. It largely meet the protein requirement of human. Microorganisms show rapid growth and do not require special culture media. It helps in reducing depletion of natural resources and reducing environmental pollution.
Thus, the correct answer is 'Many enzymes, bioactive molecules etc can be harnessed industrially.'
Question 2
1 / -0

If the food source is in the opposite direction of sun and distance from the hive is 85 meters, then scout worker bee will convey this information by

A
Round dance

B
Straight dance

C
Tail wagging dance - upward

D
Tail wagging dance - downward

Solution

A scout worker honey bee performs a waggle dance to convey the information to the rest of the hive about the food source. The direction the bee moves in relation to the hive. This indicates the direction of food with respect to direction of sun. If it moves vertically and upward, the source is directly towards the Sun. If it moves vertically and downward, the source of food is in opposite direction of sun. The duration of the tail wagging dance signifies the distance.
Thus, the correct answer is 'Tail wagging dance - downward.'
Question 3
1 / -0

First artificial hybrid was obtained by crossing sweet william and carnation in $$1717$$ by

A
G.J Mendel

B
M.S Swaminathan

C
P.Maheshwari

D
Thomas Fairchild

Solution

A. G.J Mendal is known for his discovery of fundamental laws of inheritance.
B. M.S Swaminathan is responsible for introducing and further developing high-yielding varieties of wheat in India.
C. P. Maheshwari was the first person to to grow a plant after natural fertilization in a test tube containing artificial culture medium.
D. Thomas Fairchild was responsible for first artificial hybrid.
So, the correct answer is 'Thomas Fairchild'.
Question 4
1 / -0

Read four statements (a - d) carefully.
(a) Honey is a food of high nutritive value and also finds use in the indigenous system of medicine.
(b) Beewax finds many uses in industry such as in the preparation of cosmetics and polishes of various kinds.
(c) Honey bee conveys the direction of food by tail wagging dance when food source is less than $$75$$ meters from the beehive
(d) Male individuals of honeybees are developed parthenogenetically.
How many statements among these are correct?

A
One

B
Two

C
Three

D
Four

Solution

Honey bees are main source of honey. Row honey has antioxidant that help in boosting immunity. It has a food of high nutritive value and also finds use in the indigenous system of medicine. It has a good amount of bee pollen in it, which contains a lot of nutrients needed by the body. Honeybees convey the direction of food by tail wagging dance when food source is more than 150 meters from the beehive. Male individuals are fertile and develop from sexual reproduction.
So the correct answer is 'One'.
Question 5
1 / -0

__________ is the best Indian domesticated bee.

A
Apis dorsata

B
Apis indica

C
Apis florea

D
Apis mellifera

Solution

Apis indica is the best Indian domesticated bee. It can be found in different regions and can be domesticated without many hurdles. It colonizes plains, forests, and mountains.
Hence, the correct answer is 'Apis indica'
Question 6
1 / -0

Collection of genetic variability is required in plant breeding programme because

A
It leads to inbreeding depression in hybrids

B
It is the root of any breeding programme

C
Diverse alleles in germplasm helps you to choose desirable charters

D
Both (2) and (3)

Solution

Genetic variability is the cornerstone of breeding with the advent of molecular biology, traditional interspecific, intergenetic and plant type barriers to gene transfer have been removed. By isolating the gene for a particular trait and inserting it into a new host by a range of techniques the gene becomes a part of the host.DNA.
So, the correct option is 'Both (2) and (3)'.
Question 7
1 / -0

The development of improved varieties of plants is mainly by judicious combination of.

A
Inbreeding, outbreeding and outcrossing

B
Plant breeding and tissue culture

C
Plant breeding and plant taxonomy

D
Plant breeding, tissue culture and genetic engineering

Solution

Hereditarily changed products (GM yields or biotech crops) are plants utilized in horticulture, the DNA of which has been altered utilizing hereditary designing techniques.
Plant breeding uses purposeful interbreeding (crossing) of nearly or indirectly related people to deliver new product assortments or lines with attractive properties. Plants are crossbred to present qualities from one assortment or line into another hereditary foundation.
Plant tissue culture is an accumulation of systems used to keep up or develop plant cells, tissues or organs under sterile conditions on a supplement culture mechanism of known creation. Plant tissue culture is broadly used to create clones of a plant in a technique known as micropropagation.
So, the correct option is 'Plant breeding, tissue culture, and Genetic Engineering'.
Question 8
1 / -0

The most convenient way to maintain plant germplasm is

A
Tissue culture

B
Developing new varities

C
Storing seeds

D
Treat plants to low temperature

Solution

The most convenient way to maintain plant germplasm is tissue culture which is a invitro method. It has several adavantages over in-situ (national parks/gene sanctuaries) or ex-situ ( seeds or from in vitro cultures (plant cells, tissues or organs). The advantages include storage of germplasm free from pathogens, requires less space, can be protected against natural hazards.
So the correct answer is 'Tissue culture'.
Question 9
1 / -0

Cuniculture is related to

A
Keeping of honey bees

B
Rearing of rabbits

C
Cultivation of fruits and vegetables

D
Rearing of fish

Solution

Cuniculture is the practice of breeding and raising domestic rabbits as livestock for their meat, *fur and wool.
Question 10

Select the correct statements regarding honeybees.
(i) The queen bee and the worker bees develop from fertilized eggs and are sexually females.
(ii) Males (drones) develop parthenogenetically from unfertilized eggs.
(iii) Queen bee feeds upon royal jelly and the worker bees feed upon bee bread.

A
(i) and (ii)
