  3. They are fertilised by the miasma emanating from drones.

  4. They are physically inseminated by drones outside the hives.

D Correct answer
Explanation

In apiculture, queens are physically inseminated by drones outside the beehives. Huber was the first to prove by observation and experiment that queens are physically inseminated by drones outside the beehives, usually a great distance away.

Multiple choice

Royal jelly is a nutrient fed by nurse bees to

  1. male bees

  2. a larva which is to be made the new queen

  3. worker bees to increase their efficiency

  4. all larval forms of bees

B Correct answer
Explanation

Royal jelly is fed by nurse bees to a larva which is to be made the new queen.

Multiple choice

Honey is made by

  1. queen bees

  2. drone bees

  3. worker bees

  4. larval form of bees

C Correct answer
Explanation

Worker bees produce honey from nectar.

Multiple choice

Why are all worker bees sterile?

  1. Because of miasma created by drones

  2. Because of queen substances produced by the queen

  3. Because they are not fed royal jelly

  4. Because of their congenital defect
Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation

All worker bees are sterile because of certain pheromones, called queen substances, produced by the queen.

Multiple choice

Which of the following sentences about drone bees is true?

  1. Drones synthesise honey and fertilise the virgin queen.

  2. Drones fertilise the virgin queen.

  3. Drones are reared from fertile eggs.

  4. Drones are the largest honey bees.
Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation

The sole duty of drones is to fertilise the virgin queen. At the time of mating flight, the drones follow the queen, copulate and die after copulation.

Multiple choice

How many times does a queen bee mate in its life?

  1. Once in a year

  2. Once in a lifetime

  3. Once in a day

  4. Never
Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation

Queen bee mates once in a lifetime. It stores millions of sperms in its body and uses them for producing eggs throughout its life.

Multiple choice

  2. Flower – Bouquet

  3. Cotton – Bale

A Correct answer
Explanation

Option 1 is the correct answer because it relates to living beings, whereas options (2) and (3) refer to “non-living things”.

Multiple choice

In oak, pollination is facilitated mainly by

  1. birds

  2. droplets of rain

  3. insects

  4. wind
Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation

Oak trees are wind-pollinated (anemophilous). They produce inconspicuous flowers with copious, lightweight pollen grains adapted for wind dispersal. Oak pollen is a common allergen because it's wind-borne. Wind pollination is the primary mechanism, not insects, birds, or rain droplets.
