Biology of Insects and Pollination Questions
A
Correct answer
Explanation
In a honey bee colony, there is typically only one queen bee at a time. The queen is the sole reproductive female in the colony and lays all the eggs. Multiple queens would create conflict as they would compete for dominance. The colony operates with this single-queen system as part of its social structure.
B
Correct answer
Explanation
Honey bees store honey, pollen, and their eggs in wax structures called combs within the hive. The hexagonal cells of the comb are where the bee colony lives and stores food. While beehives can be kept in boxes, the internal structure is called a comb.
A
Correct answer
Explanation
Poultry specifically refers to domesticated birds like chickens, ducks, turkeys, and similar fowl raised for meat or eggs. Fish, oxen (cattle), and honey bees belong to entirely different animal categories.

Honey bee
-
Mosquito
-
Cockroach
-
Scorpion
A
Correct answer
Explanation
Honey bees are classic examples of social insects because they live in highly organized colonies with division of labor, cooperative brood care, and overlapping generations. Social insects work together for the survival of the entire colony.
-
Drone
-
Beekeeper
-
Worker
-
Apis
A
Correct answer
Explanation
In honey bee colonies, drones are the male bees whose primary role is to mate with the queen. Workers are female bees that perform all the labor in the hive, while beekeepers are humans who manage bee colonies. Apis is the scientific genus name for honey bees.
-
Worker bee
-
Pupa
-
Queen bee
-
Drone bee
A
Correct answer
Explanation
Worker bees perform all essential colony tasks including cleaning, feeding larvae, collecting nectar and pollen, and building honeycombs. The queen bee's sole function is egg-laying, while drones exist only to mate with the queen, and pupae are developmental stages not functional members.
-
Dancing
-
Flying
-
Singing
-
Jumping
A
Correct answer
Explanation
Honey bees perform specific dance movements called the 'waggle dance' to communicate the location and direction of food sources to other bees in the hive. Flying is general movement, while bees don't sing or jump as communication methods.
-
Apis
-
Ant
-
Bumble bee
-
Termite
A
Correct answer
Explanation
Apis is the scientific genus name for honey bees, which produce honey - a valuable food product for humans. Honey bees are the only insects on this list that produce a food substance directly consumed by humans.
-
Queen
-
Worker
-
Drone
-
Servant
D
Correct answer
Explanation
A honey bee colony consists of three distinct castes: Queen (the reproductive female), Workers (non-reproductive females who perform all colony tasks), and Drones (males whose sole purpose is mating). There is no 'Servant' caste in honey bee society.
B
Correct answer
Explanation
Honey bees have four wings total - two forewings and two hindwings. This is characteristic of Hymenoptera order insects. The 'Two' option is incorrect, 'One pair' would mean two wings, and 'Six' is characteristic of some other insects.

-
mosquitoes
-
small reptiles
-
plant pathogens
-
aphids
-
none of these
D
Correct answer
Explanation
Yes, it is the correct answer. Ladybugs are so popular in terms of aphid control because they eat nearly all aphids. Adult ladybugs can eat up to 1000 aphids a day and as larva, about half as many.

B
Correct answer
Explanation
(B), The whole sentence is following a continuous formation, that is 'ing' is added after each verb. Hence the incorrect portion should also follow the same, so (B) is correct.
-
Many flowering plants benefit of pollination by adult butterflies and moths.
-
Many flowering plants benefit with pollination of adult butterflies and moths.
-
Many flowering plants benefit by pollination from adult butterflies and moths.
-
Many flowering plants benefit from pollination in adult butterflies and moths.
-
Many flowering plants benefit from pollination by adult butterflies and moths.
E
Correct answer
Explanation
Explanation for (1): The correct usage is 'benefit from' hence. This option adds another error by changing 'pollination due'; hence (5) is the answer.
Explanation for (2): The correct usage is 'benefit from' hence.
Explanation for (3): The correct usage is 'benefit from' hence.
Explanation for (4): 'Pollination' does not take place in butterflies and moths.
Justification for (5): The correct usage is 'benefit from'. Hence (5) is the answer.
