Question 1
1 / -0

Cryopreservation is germplasm protection by ?

A
Crossing with wild varieties

B
Energy flow in different trophic levels

C
Both A and B

D
Low temperature

Solution

Cryo-preservation or cryo-conservation is a process where organelles, cells, tissues, extracellular matrix, organs or any other biological constructs (germplasm i.e., genetic resources for preservation) susceptible to damage caused by unregulated chemical kinetics are preserved by cooling to very low temperatures, typically −80 °C using solid carbon dioxide or −196 °C using liquid nitrogen. At low enough temperatures, any enzymatic or chemical activity which causes damage to germplasm is stopped.
So, the correct answer is 'Low temperature'.
Question 2
1 / -0

Rearing of bees is

A
Sericulture

B
Apiculture

C
Silviculture

D
Horticulture

Solution

Apiculture is the maintenance of bee colonies, commonly in man-made hives, by humans. It is also called as beekeeping. A beekeeper (or apiarist) keeps bees in order to collect their honey and other products that the hive produce (including beeswax, propolis, flower pollen, bee pollen, and royal jelly), to pollinate crops, or to produce bees for sale to other beekeepers. Hence, the rearing of bees is apiculture.
So, the correct answer is 'apiculture'.
Question 3
1 / -0

Select the correct match.

Column-A Column-B
(a) Rock bee (i) Apis indica
(b) Little bee (ii) Apis dorsata
(c) European bee (iii) Apis florea
(d) Indian bee (iv) Apis mellifera

A
a- iv, b-i, c-iii, d-ii

B
a-iii, b-ii, c-iv, d-i

C
a-ii, b-iii, c-iv, d-i

D
a-iv, b-iii, c-i, d-ii
Solution
- Rock bee is also called a giant honey bee. The scientific name of rock bee is Apis dorsata.
- It is mainly found in the forest area. This is the largest of the honey bee species. Little bee is also called a red dwarf honey bee.
- The scientific name of little bee is Apis florea. It is found in southeastern Asia. European bee is also called a western honey bee.
- The scientific name of the European bee is Apis mellifera. It is the most common type of honey bee found in the world.
- The scientific name of Indian bee is Apis indica. It is subspecies of Asiatic honey bee.
Thus, the correct answer is option C.
Question 4
1 / -0

In a colony of honey bee, male drones are originated by

A
Diploid parthenogenesis

B
Cyclic parthenogenesis

C
Arrhenotoky

D
Thelotoky

Solution

Honey bees are classified into three categories queen, worker and drone. Drones are male honey bees. They are developed from unfertilised female eggs. This phenomenon is called arrhenotoky.
Pathenogenesis means the development of unfertilised eggs or haploid eggs into young ones as the development of drones female bee develops from diploid fertilized ovum. Thelotoky is also a type of parthenogenesis. Thus, the correct answer is option C.
Question 5
1 / -0

Cryopreservation is germplasm protection by

A
Crossing with wild varieties

B
Energy flow in different trophic leak

C
Both A and B

D
Low temperature

Solution

Cryopreservation is germplasm protection by low temperature. It is the process in which organelles, cells, tissues, organs are prevented from damage caused by unregulated chemical kinetics by preserving it at low temperatures. The temperature used is typically −80$$^0$$C using solid carbon dioxide or −196$$^)$$C using liquid nitrogen.
So, the correct answer is 'Low temperature'.
Question 6
1 / -0

Which of the following is an algal source of SCP?

A
Candida

B
Methanobacillus

C
Chlorella

D
Saccharomyces

Solution

Single cell protein is a protein obtained from pure or mixed cultures of algae, bacteria, etc. that have 30-70% of protein content in their dry mass. SCP are rich source of protein (60-72%), vitamins, amino acids, minerals, and crude fibers. Hence they are extensively used as food. There are many organisms that are used for the production of SCP. They are Chlorella, Spirulina, and Chlamydomonas.
Thus, the correct answer is option C.
Question 7
1 / -0

Which is not a major carp?

A
Cirrhinus mrigala

B
Labeo rohita

C
Puntius tieto

D
Ctenopharyngodon idella

Solution

A. Cirrhinus mrigala, known as the white carp, is a ray finned fish.
B. Labeo rohita, commonly known as Rohu, is a carp fish found in rivers of South Asia.
C. Puntius tieto is a small and freshwater fish. It belongs to family Cyprinidae.
D. Ctenopharyngodon idella is known as the grass carp. In aquaculture, it is reported to have largest production.
Hence, Puntius tieto is not a major carp. So, the correct answer is 'Puntius tieto'.
Question 8
1 / -0

Given below are assertion and reason.

Point out if both are true with reason being correct explanation (A),
Both true but the reason is not correct explanation (B),
The assertion is true but the reason is wrong (C),
Both are wrong (D).

Question 9
1 / -0

Honey is____________.

A
Alkaline

B
Acidic

C
Neutral

D
Basic after some days.

Solution

Honey is
$$ \Rightarrow $$ neutral.
$$ \rightarrow $$ The honey is a neutral, neutral valuable
tonic for human body.
$$ \rightarrow $$ it is a sueet, viscous edible fluid.
$$ \rightarrow $$ chemical composition of honey is - ash (1.00%)
vitamin (0.2 to 0.5%) minerals (0.22 to 0.3%)
water (27.80%)Sugar (20 to 40%) Amino acids
and Enzymes.
$$ \bullet $$ The colour, flavour and small of honey
depend on the flower from which neclar
is collected.
Question 10
1 / -0

Bee dances are meant for

A
Courtship

B
Communication

C
Recreation

D
Instinct.

Solution

Bee dances are meant for
$$ \Rightarrow $$ Communication
$$ \rightarrow $$ prof karl van Frisch decoded the language
of "bee dance and got "noble prize".
He discovered scout bees performer lesso types
of dance for Communication.
i) Round dance when a newly discovered
food source is close to the hive.
ii) Tail wagging dance is performed for
