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'.

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 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.
