In which of the following bee, wax glands are found?

  1. Queen bee

  2. Drone

  3. Workers

  4. Both A and C

Show answer
Correct Option: C
Explanation:

Worker bees, which live only around 35 days in summer, make wax from about the 10th day of their lives to the 16th. When workers are roughly 10 days old, they develop special wax-producing glands in their abdomens. The glands convert the sugar in the honey into wax, which seeps through small pores in the bee’s body leaving tiny white flakes on its abdomen. These bits of wax are then chewed by the bees. The chewed wax is added to the construction of the honeycomb. Hence, option C is correct.

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

  1. 10

  2. 15

  3. 20

  4. 1

Show answer
Correct Option: D
Explanation:

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.

The honey bees exhibit a type of dance to communicate the location of food. What is this known as?

  1. Waggle dance

  2. Tap dance

  3. Round dance and waggle dance

  4. Break dance

Show answer
Correct Option: C
Explanation:

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 C.

Life span of worker bee is ................

  1. 10 days

  2. 15 days

  3. 6 weeks

  4. 10 weeks

Show answer
Correct Option: C
Explanation:

Workers bee are the smallest castes. The life span of an adult worker bee varies with the time of the year. It takes about twenty one days in their development from egg to adult and when the colony is active in spring and summer, worker bee may live as long as 5-6 weeks. During the inactive period in winter a worker bee lives five months or more. Hence, option C is correct answer.

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

  1. Monosaccharides

  2. Disaccharides

  3. Polysaccharides

  4. Fats

Show answer
Correct Option: A
Explanation:

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.

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

  1. Unfertilized eggs

  2. Fertilized eggs

  3. Larvae fed by royal jelly

  4. Fasting larvae

Show answer
Correct Option: A
Explanation:

The queen after fertilization lays fertilized and unfertilized eggs both. From unfertilized eggs male bees emerge which are known as drones.

Honey bee is of greatest use to man due to which reason?

  1. We get honey from them.

  2. Helps in cross pollination.

  3. Is of medicinal value.

  4. It entertains.

Show answer
Correct Option: B
Explanation:

The greatest value of the honey bee to man is in the pollination of flower. Another financial return is from the production of bee wax and honey.

Which of the following is a correct statement?

  1. Drone is diploid.

  2. Apis indica is largest wild bee.

  3. Wax is excretory product of bee.

  4. Frisch discovered communication in bees.

Show answer
Correct Option: D
Explanation:

1st statement is incorrect, as drones of the honey bee are haploid and not diplod. They develop parthenogenetically from unfertilized eggs. 

2nd statement is incorrect, as Apis dorsata laboriosa and not Apis indica, the Himalayan honey bee, is the world's largest honey bee.
3rd statement is incorrect, as bee's wax is not a waste material, it is secreted by special wax glands present in the abdomen. It is used for making the hives of honeybee.

4th statement is correct, as Karl Von Frisch discovered the communication and transmission methods in the honey bee during a number of experiments and found out that when a foraging bee returns to the hive, it performs a 'waggle dance'. 
Hence, option D is correct.

  1. C. Darwin

  2. K. V. Frisch

  3. W. Harvey

  4. H. G. Khorana

Show answer
Correct Option: B
Explanation:
-K.V. Frisch was an Austrian ethologist who receive the Nobel prize in physiology or medicine in $1913$
-His work centered on investigation of the sensory perceptions of honey bee and he was one of the first to translate the meaning of the waggle dance.
-His theory, described in his $1927$ book Aus dem leben der Bienen(translated into English as the Dancing Bees).
