Question 1
1 / -0

Honeybee after discovering the new source of nectar or honey can convey this information but

A
Cannot convey the direction

B
Can convey the direction by round or tail wagging dance

C
Can convey the direction by round dance only

D
Can convey the direction by tail wagging dance only

Solution

The honey bees exhibit 2 types of dance to communicate the location of food the round dance and the tail-wagging or waggle dance.
The round dance is used for food sources 25-100 meters away from the hive or closer. After distributing some of her new-found nectar to waiting bees the scout will begin running in a small circle, switching direction every so often. The round dance does not give directional information. Bees elicited into foraging after a round dance fly out of the hive in all directions searching for the food source they know must be there.
As the food source becomes more distant the round dance is replaced by the waggle dance. The waggle dance includes information about the direction and energy required to fly to the goal.
Therefore, the correct answer is option B.
Question 2
1 / -0

Number of queens in a hive is ...................

A
10

B
15

C
20

D
1

Solution

Commonly one queen is found to be present in each hive and feeds on royal jelly. She is the queen in real sense as the mother of the colony.
Question 3
1 / -0

In honey bees, the drones (males) are produced from ..................

A
Unfertilized eggs

B
Fertilized eggs

C
Larvae fed by royal jelly

D
Fasting larvae

Solution

The queen after fertilization lays fertilized and unfertilized eggs both. From unfertilized eggs male bees emerge which are known as drones.
Question 4
1 / -0

Honey mainly consists of ........................

A
Monosaccharides

B
Disaccharides

C
Polysaccharides

D
Fats

Solution

Honey is composed primarily of the sugars glucose and fructose; its third greatest component is water. It consists of fructose (45%) and glucose (32-37%) that is monosaccharides and because of glucose and fructose, they gets its sweetness. Hence, option A is correct.
Question 5
1 / -0

Which one of the following substances is at its lowest level present in fish food?

A
Actin

B
Myosin

C
Cholesterol

D
Tissue fluid

Solution

Cholesterol is a common sterol found in many animals and some plants. It is present in very less amount in fish flesh.
Therefore, the correct answer is option C.
Question 6
1 / -0

Isinglass is a type of by product of fish industry which is principally used for .....................

A
Feeding cattle, pigs and poultry

B
Preparation of paints and varnishes

C
Clarification of vinegar, wines and beer

D
Production of insulin

Solution

Isinglass is principally used for clarifying of wines, bear and making purse, honey comb, book and ribbon. The isinglass prepared in Russia is of best quality in the world.
Question 7
1 / -0

Choose the minor carp from the following.

A
Cyprinus carpio

B
Labeo calbasu

C
Labeo bata

D
Ctenopharyngodon idella

Solution

Carps are various species fresh water and oily fish and belong to the family Cyprinidae. These are mostly cultured and domesticated in fisheries and aquaculture farms for food and ornamental purpose. The endemic species of carps are divided into two sub-groups: "major carps" and "minor carps". Labeo bata is a minor carp is found in India and Bangladesh and is generally cultivated
So, the correct answer is 'Labeo bata'
Question 8
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
Vasopressin and oxytocin

Solution

Induced breeding of fish is a technique of producing fish by pituitary injectioning. 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 9
1 / -0

Isinglass is prepared from ..................

A
Ichthyophis

B
Musk deer

C
Fishes

D
Lizards

Solution

Isinglass is a transparent, almost pure gelatin prepared from the swim bladder of the sturgeon and certain other fishes such as cat fishes and carps and used as an adhesive and a clarifying agent. Hence, option C is correct.
Question 10
1 / -0

Induced breeding is effective in which of them?

A
Pisciculture

B
Sericulture

C
Apiculture

D
Lac culture

Solution

Induced breeding is effective in pisciculture as induced breeding is an artificial process by means of which the extract of the pituitary is introduced into the body of both the matured male and female fishes, then the carps after being excited lay eggs in the pond water and subsequently, fertilization takes place. This process of breeding is also known as hypophysation.
So, the correct answer is option A.
