Question Discussion & Solution

The correct option is Most of the bees in the hive are worker bees.

• Every honey bee colony comprises a single queen, a few hundred drones and several thousand worker castes of honey bees.
• A queen bee is the only female bee in the hive that gets to reproduce.
• Worker bees are all female and are all offspring of the queen. 
• Queen is a fertile, functional female, the worker is a sterile female and the drone is a male insect.
• Queen and worker develop from the fertilized egg while drone develops from an unfertilized egg.
• Further differentiation of queen and worker depends on the quality and quantity of food that is fed to the queen or worker larvae.

Explanation:

​Every beehive has one male bee and many female bees → Inorrect.

Most of the bees in the hive are worker bees → Correct

The study of honey bee is sericulture → Inorrect.

Beehives are octagonal in shapes→ Incorrect. (Hexagonal)

​Additional Information

The queen:

• ​There is only one queen in a colony and considerably larger than the members of other castes.
• Swarming is the natural method that honeybee colonies use for multiplying their colonies.
• The old queen is killed as soon as the new queen is fertilized.
• The phenomenon of raising a queen in the off-season is called supersedure.
• The normal lifespan of a queen is 3 years.

​The drone:

• ​The drones are male bees with no sting.
• They are much larger and stouter than either the queen or the workers.
• Their only function is to impregnate the young queen a task which they are unable to perform until they are about 10 days of age.
• They also help in the maintenance of hive temperature. 
• The drones are produced by unfertilized eggs of the queen, or by those workers which take up the reproductive function due to the absence of a queen in a colony.
• The normal lifespan of a drone is 57 days. 

​The worker:

• ​Smallest inhabitants of the beehive.
• They are imperfect females incapable of laying eggs.
• Worker bees primary duties are cleaning, feeding developing larva once hypopharyngeal glands develop, ripening of honey, secreting/moulding of wax into combs.
• The lifespan of a worker is about 4 weeks during the active season and 8 to 10 weeks during the less active season.
• On certain occasions when the colony is in need of a queen, some of the workers start laying eggs from which only drones are produced.
• These workers called laying workers.

Table and chair both are made of wood

Similarly, shoes and belt both are made of Leather.

Hence, X is in North-west of C.

CONCEPT:

• Power: The rate of work done is called power.
  • It is denoted by P.
  • Mathematically it is written as

\(Power\;\left( P \right) = \frac{{\;W}}{{t}}\)

CALCULATION:

Given - mass of 1^st person (m₁) = 80 kg, mass of 2^nd person (m2) = 60 kg, time (t₁) = 12 sec, and time (t2) = 11 sec​

• The power to take an object to a certain height in 12 sec by 1^st person is 

\(\Rightarrow P_1 = \frac{mgh}{t}=\frac{80gh}{12}\)       ----(1)

• The power to take an object to a certain height in 11 sec by 2^nd person is 

\(\Rightarrow P_1 = \frac{mgh}{t}=\frac{60gh}{11}\)       ----(2)

On dividing equations 1 and 2, we get

\(\Rightarrow \frac{P_1}{P_2} =\frac{\frac{80gh}{12}}{\frac{60gh}{11}}=\frac{11}{9}\)

Given that Mars, Planets, Celestial Bodies.

All Mars situated in Planets and all Planets are situated in Celestial Bodies.
