C
6-7 months

D
10-12 months.
Question 2

A
Vegetable wax

B
Hard paraffin wax

C
Shellac

D
Lanolin

Solution

Sealing wax is a wax material of a seal which, after melting, hardens quickly forming a bond that is difficult to separate without noticeable tampering. Typically these are a mixture of wax and resin; usually beeswax and shellac.

Honey Bee performs round dance to indicate food source. The distance between hive and food source is

A
50 m

B
100 m

C
1000 m

D
2000 m.

Solution

HONEY BEE CHARACTERISTICS
$$\rightarrow$$ $$15$$mm long
$$\rightarrow$$ Body is segmented into stinges, legs, antena, three segments of thorax, six segments of abdomen
$$\rightarrow$$ Thorax of the bee consists of wings, legs and mucles that control their movement.
$$\rightarrow$$ In each colony, one egg laying queen is present who produces $$2000$$ eggs a day.
$$\rightarrow$$ Adult workers tend the larvae inside the cells.
$$\rightarrow$$ Drones(male bees) mate with the queen, after which they die.
$$\rightarrow$$ They follow haplodiploidy.
$$\rightarrow$$ Lifespan is about $$4$$ months for ever wintering drones. However the average lifespan is about $$5-6$$ weaks or $$1-2$$ months.
Honey bees communicate through dance language:-
$$1)$$ Waggle dance when food is $$150$$ to $$200$$ metres away
$$2)$$ Round dance when food source is $$25$$ to $$50$$ metres away.
Correct option A.
Question 4
1 / -0

Sexing in poultry is done by observing ______.

A
Feathers

B
Comb

C
Vent

D
Beak

Solution

Vent sexing, also known simply as venting, involves squeezing the feces out of the chick, which opens up the chick's anal vent (called a cloaca) slightly, allowing the chicken sexer to see if the chick has a small "bump", which would indicate that the chick is a male.
Hence the correct answer is (C)
Question 5
1 / -0

Read the following four statements A-D.
(A) Honey is a food of high nutritive value and also find use in indigenous system of medicine.
(B) Bee-keeping is the maintenance of hives of honey bee for the production of honey only.
(C) The increased demand of honey has led to small scale bee-keeping practices.
(D) Bee-keeping can be practiced in any area where there are sufficient bee pastures of wild shrubs, fruit orchards and cultivated crops.
How many of the above statements are correct?

A
Three

B
Two

C
One

D
None of the above

Solution

The corrected form of the given statements are:
(A) Honey is a food of high nutritive value and also finds use in indigenous system of medicine.
(B) Beekeeping or Apiculture is the maintenance of hives of honeybees for production of honey.
(C) The increased demand for honey has led to large scale beekeeping practices.
(D) Beekeeping can be practised in any area where there are sufficient bee pastures of some wild shrubs, fruit orchards and cultivated crops.
So, out of the given statements, only three statements are correct.
Thus, the correct answer is 'Option A- Three'.
Question 6
1 / -0

Put a tick mark against the correct alternative in the following statement :
Which one of the following is the common breed of buffalo is found in Gujarat?

A
Surti

B
Murrah

C
Gir

D
Mehsana

Solution

Mehsana is a dairy breed of buffalo found in Mehsana town in Gujarat. The breed is evolved out of crossbreeding between the Surti and the Murrah. The milk yield is 1200-1500 kgs.
hence, the correct answer is 'Mehsana'
Question 7
1 / -0

Grains of major cereals and millets lack amino acid ______.

A
Methionine and cysteine

B
Methionine and lysine

C
Tryptophan and cysteine

D
Lysine and tryptophan

Solution

D. Lysine and tryptophan
Solution : Major cereals lack the amino acids like lysine and tryptophan that are generally plentiful in the protein rich diets like legumes ( e.g., bean).
So the correct answer is "Lysine and tryptophan".
Question 8
1 / -0

Read the following statements regarding poultry farm management.
(i) Poultry birds include chicken, ducks, turkey and geese.
(ii) Brooder house should be crowd-free, rain proof and protected from predators.
(iii) The most common egg-type variety used for commercial production throughout the world is single comb white leghorn and its various strains.
(iv) Approximately 14 to 16 hours of light including daylight are required for optimum egg production.
Which of the above statements are correct?

A
(iii) and (iv)

B
(i), (ii) and (iii)

C
(i), (iii) and (iv)

D
(i), (ii), (iii) and (iv)

Solution

All the statements given above regarding poultry farm management are correct . Poultry farm includes chickens, ducks, turkey and geese. Brooder house are typically wooden movable structures heated enclosure by electric for raising baby poultry. It is crowd free , rainproof and protected against predators . This will led to higher rate of egg production. The most common type of egg variety used for commercial production are comes from Leghorn which requires a photoperiod of 16 hours for optimum egg production . Reduction in photoperiod leads to reduce egg yield.
So, the correct option is 'Option D' .
Question 9
1 / -0

Which of the following is incorrectly matched?

A
Disease - Black rot of crucifers; Causative Organism - Bacteria

B
Disease - Brown rust of wheat; Causative Organism - Fungi

C
Disease - Late blight of potato; Causative Organism - Virus

D
Disease - Red rot of sugarcane; Causative Organism - Fungi

Solution

A.Correct option C

B.Explanation for the correct option:

1. Late blight of potato is not caused by virus.

2. Its causative agent is a fungus name Phytophthora infestans.

3. It can result in crop failure in a very short time.

4. Winter season is the most favorable for this fungus to attack potato mainly in the lower region of the crop.

6. Symptoms includes purple depressions over the crop.
So, the correct answer is 'Disease - Late blight of potato; Causative Organism - Virus'
Question 10
1 / -0

Fill up the blanks in the following paragraph by selecting the correct option.
Inbreeding increases (i). Thus inbreeding is necessary if we want to evolve a (ii) in any animal. Inbreeding exposes harmful (iii) genes that are eliminated by selection.

A
(i) heterozygosity, (ii) pure line, (iii) dominant

B
(i) heterozygosity, (ii) breed, (iii) recessive

C
(i) homozygosity, (ii) pure line, (iii) recessive

D
(i) homozygosity, (ii) breed, (iii) dominant

Solution

Inbreeding refers to the mating of more closely related individuals within in the same breed for upto 4-6 generations. Inbreeding increases homozygosity (i). Thus inbreeding is necessary if we want to evolve a pure line (ii) in any animal. Inbreeding exposes harmful recessive (iii) genes that are eliminated by selection.
So, the correct option is 'Option C' .
