How do mosquitoes locate human beings to bite?

  1. They have sharp eyes

  2. They use sound to locate humans

  3. They use their sense of smell

  4. None of the above
Reveal answer Fill a bubble to check yourself
C Correct answer
Explanation
  • Many insects, mosquitoes included, are attracted by the odour of the carbon dioxide (CO2) gas that humans and other animals naturally exhale.
  • However, mosquitoes can also pick up other cues that signal a human is nearby. They use their vision to spot a host and thermal sensory information to detect body heat.

So, the correct answer is 'They use their sense of smell'.

The use of honeybee is

  1. to help in pollination

  2. production of bees wax

  3. production of honey

  4. all of these.
Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation

Honey bees are flying insects which help in pollination of flowers. It is very attracted to yellow-orange coloured flowers. It widely produces honey which has a high nutritive value and edible. It is used in the production of medicines, wax, polishes, cosmetics, waterproofing agents and as a lubricant.

So, the correct option is 'Option D'.

Select the correct statements regarding honeybees.
(i) The queen bee and the worker bees develop from fertilised eggs and are sexually females.
(ii) Males (drones) develop parthenogenetically. from unfertilised eggs.
(iii) Queen bee feeds upon royal jelly and the worker bees feed upon bee bread.

  1. (i) and (ii)

  2. (ii) and (iii)

  3. (i) and (iii)

  4. (i), (ii) and (iii)
Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation

The female queen bee produces new offspring by laying eggs that have been fertilized by sperm from male drones. These drones are raised in cells that are significantly larger than the cells used for workers. A type of asexual reproduction in which egg develops without fertilization to form a new individual. If parthenogenesis (type of asexual reproduction in which egg develops without fertilization to form a new individual) takes place in bees, a drone or male bee is produced. Royal jelly is a honey bee secretion that is used in the nutrition of larvae, as well as adult queens. It is secreted from the glands in the hypo-pharynx of nurse bees while the worker bees are fed the bee bread. As a result of the difference in diet, the queen will develop into a sexually mature female, unlike the worker bees. Queens are raised in specially constructed queen cells.

So, the correct option is '(i), (ii) and (iii)'.

Which of these build the hive, collect nectar and pollen, clean the cells and protect the hive?

  1. Queen bee

  2. Worker bee

  3. Drone

  4. Male bee
Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation

The worker bees are the smaller, sterile female bees. They are called as nurse or housekeepers. They are involved in taking care of the hives and the young ones. They help in building the hives and protect the hives from the other animals. They help in pollination, collect the nectar and transfer the pollens between the flowers. 

Thus, the correct answer is option B.

What is the scientific name of the Italian bee?

  1. Apis indica

  2. Apis dorseta

  3. Apis mellifera

  4. Apis florae
Reveal answer Fill a bubble to check yourself
C Correct answer
Explanation
  • Apis mellifera is an Italian bee variety. It is the most common honey bee and called as a common or western honey bee because of the large production of honey. 
  • Apis indica is the Indian honey bee. Apis dorseta is the giant honey bee and Apis florae are the dwarf honey bee of southeast Asia.

     Thus, the correct answer is option C.

Special dance in honey bee is for

  1. Reproduction

  2. Destruction of enemy bees

  3. Search of food

  4. Convey the information of food source
Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation

Honey bees performs two type of dances for discovered food source. (1) Round dance is performed when a newly discovered food source is close to hive. (2) Tail wagging dance is performed for long distance source of food.

Which of the following processes include the mass emigration of bees to settle down elsewhere in order to form a new hive ?

  1. Migration

  2. Swarming

  3. Spawning

  4. Carding
Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation

The mass emigration of bees in a swarm to settle down elsewhere in order to form a new hive is called swarming. The queen bee migrates with the worker bees to a new place. Thousands of bees are present in a single swarm and this takes place mostly in the spring season. Thus the correct answer is option  B.

  1. Queen bee

  2. Silkmoth

  3. Female laccifer

  4. Male laccifer
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation
  • The queen bee is the only reproductive female in the beehive.
  • Queens are developed from larvae selected by worker bees and specially fed in order to become sexually mature.
  • The characteristics of the queen bee are  It devoid of wings, It has the bright red body, Head, thorax and abdominal regions are not very much distinct.
  • So, the correct answer is 'Queen bee'.

In which of the following, parthenogenesis is observed?

  1. Honey bee

  2. Silkworm

  3. Earthworm

  4. House fly
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

Parthenogenesis is a natural form of asexual reproduction found most commonly in lower organisms and plants. It is shown by honeybee, where male honeybees (drones) are produced parthenogenetically from unfertilized eggs. The only function of drones is to fertilize the queen bee. Hence, option A is correct.
