  • Question 2
    1 / -0
    A waxy substance produced by honey bee to repair combs is called as................
    Solution
    Propolis is a red or brown resinous substance collected by honeybees from tree buds, used by them to fill crevices and to fix and varnish honey combs. Hence, option A is correct.
  • Question 3
    1 / -0
    The stimuli through which a dancing scout bee communicates the location of a food source to other worker bees in a hive are 
    Solution
    Honey bees like insects communicate through chemicals and odors. Besides these they also use specific behaviors such as dances to convey information about the availability and type of resources in the environment, and the location of the same. The dancing scout bee's body generally points in the direction of the food source and the sound produced during the dance indicates the profitability and availability of food. Hence, the scout bee uses acoustic stimuli to communicate the location and source of food to other worker bees.
  • Question 4
    1 / -0
    The fungus used for the commercial production of SCP is
    Solution
    SCP is known as single cell protein which is edible unicellular proteins. Filamentous fungi used for SCP production are Chaetomium celluloliticum,  Fusarium graminearum, Paecilomyces varioti, which grows on cellulose waste, starch, and sulphite, respectively and contain about 50 - 55 % protein.
    So, the correct answer is option B
  • Question 5
    1 / -0
    There are two types of elephants, African and Indian. African elephants have
    Solution
    African elephants are elephants of the genus Loxodonta. Indian elephants have small ears, high domed forehead with 2 prominance on top of the skull but the African elephants have large ears, convex sloping forehead and tusks in both sexes. African elephants are found in Eastern, Southern, Central, and West Africa in dense forests, mopane and miomo woodlands, Sahelian scrub or deserts. Hence, option D is correct.
  • Question 6
    1 / -0
    In which part of the body, pollen basket is found in the honey bee?
    Solution
    The pollen basket is an arrangement of hairs found on the tibia of the metathoracic legs of some bees. The bees collect pollen and having moistened it with saliva using their tongues, they transfer it to their hind legs and pack it into the pollen basket. By packing pollen in this manner they compact it so that it can be easily carried back to the hive or nest. 
    Therefore, the correct answer is option C.
  • Question 7
    1 / -0
    Nobel prize winner for the discovery of method of interpersonal communication in honey bee is ......................
    Solution
    Karl von Frisch of Germany was awarded Nobel prize in 1973 for his discovery in the field of organisation and elicitation of individual and social behaviour pattern in bees. He showed that honey bees use a dance language to communicate food locations to other bees. He found two types of dance - round and waggle dance. Hence, option A is correct.
  • Question 8
    1 / -0
    If a honey bee is conveying an information, by round dance then the distance of source will be about
    Solution
    The round dance is performed by the worker bees when the food source is within a 50 metres of the hive. The bee runs one way in the circle, stops and then runs the other way. During the dance the worker bee passes a sample of the nectar to the other workers so they know the taste and smell of the source. 
    Therefore, the correct answer is option B.
  • Question 9
    1 / -0
    Which of the following countries is the lowest in milk yield per cow?

    Solution
    • According to 2011 FAO report, India produces more than 50000 tons of milk. 
    • It ranks fifth in the world in its population of cattle and buffaloes but it is lowest in milk yield per cow that is about 1000 liters per year. 
    • The global average for milk production is approximately 2,200 liters per cow.

    Therefore, the correct answer is option A.
  • Question 10
    1 / -0
    Sting apparatus in honey bee is a modified form of ...............
    Solution
    The stinging apparatus of the honey bee is a modified ovipositor (egg laying tube) that all bees and wasps have. In some bees and wasps, the ovipositor is nothing more than a simple egg-laying tube designed to get eggs into hard to reach nooks, while in others it is stiffened to allow holes to be made in wood or penetrate the bodies of other insects in order to lay eggs. As the stinger is a modified egg laying tube, only the female bees posses a sting.
