The Tassar silk moth generally feeds on the Oak trees.
-
adult of the Tassar silk moth
-
egg of Tassar silk moth
-
larvae of Tassar silk moth
-
pupa of Tassar silk moth
-
cocoon of Tassar silk moth
A
Correct answer
Explanation
'Antheraea mylitta' is the scientific term of the adult of the Tassar silk moth.
-
By seeing them
-
By their smell
-
By hearing their voice
-
By touching them
B
Correct answer
Explanation
An ant recognises its group members by their smell. It is found that when ants move they leave a smell on the ground.
-
Ant
-
Mosquito
-
Silk worm
-
Eagle
D
Correct answer
Explanation
Eagle is a bird with strong eye sight and ants, mosquitoes and silk worms are insects with strong sense of smell.
-
By seeing you
-
By hearing you
-
By the smell of your body
-
By the smell as well as the heat of your body
D
Correct answer
Explanation
They can find you by the smell of your body as well as the heat of your body.
B
Correct answer
Explanation
Silkworm can find its female partner by her smell.
-
insectivorous plants
-
carnivorous plants
-
omnivorous plants
-
herbivorous plants
A
Correct answer
Explanation
Insectivorous plants trap insects and other animals to eat them. They are also called pitcher plants.
-
Ant
-
Honey bee
-
Housefly
-
Centipede
-
Butterfly
D
Correct answer
Explanation
In the given options all the animals are insects having three pairs of legs but centipede has more legs than these insects.
-
They memorise their landscape
-
They use polarization of light to form a compass
-
They use pheromone trails
-
They dance to indicate direction and distance of food from the colony
B
Correct answer
Explanation
Saharan desert ants (Cataglyphis) navigate using the polarization patterns of sunlight, which remain stable even when the sun is obscured. They do not rely on landmarks (absent in desert), pheromone trails (ineffective in shifting sands), or dance communication (unique to honeybees).
-
Bees
-
Wasps
-
Hornets
-
All of these
D
Correct answer
Explanation
Müllerian mimicry occurs when multiple harmful or unpalatable species evolve similar appearances to reinforce predator avoidance. Bees, wasps, and hornets all share similar black and yellow coloration patterns that warn predators of their stinging ability. This is distinct from Batesian mimicry where a harmless species imitates a harmful one.
-
Alert colony
-
Release aggression
-
Both 1 and 2
-
Mark territory
-
Both 1 and 4
D
Correct answer
Explanation
In social insects, alarm pheromones do not involve territory marking. Territory marking by pheromones is observed in mammals.
-
looping to left and then to right
-
looping to right and then to left
-
looping to left, then straight, then to right and again straight
-
looping to right, then straight, then to left and again straight
-
they do not loop
D
Correct answer
Explanation
Waggle dance is a term used in beekeeping and ethology for a particular figure-eight dance of the honey bee. By performing this dance, successful foragers can share, with other members of the colony, information about the direction and distance to patches of flowers yielding nectar and pollen, to water sources, or to new housing locations. A waggle dance with a very short waggle run used to be characterized as a distinct (round) recruitment dance. A waggle dance consists of one to 100 or more circuits, each of which consists of two phases: the waggle phase and the return phase. A worker bee's waggle dance involves running through a small figure-eight pattern: a waggle run (aka waggle phase) followed by a turn to the right to circle back to the starting point (aka return phase), another waggle run, followed by a turn and circle to the left, and so on in a regular alternation between right and left turns after waggle runs.

Nico Tinbergen
-
Edward Thorndike
-
Konard Lorenz
-
None of the above
A
Correct answer
Explanation
Karl Von Frisch’s work centered on investigations of the sensory perceptions of the honey bee and he was one of the first to translate the meaning of the waggle dance. He demonstrated bee dance in 1967. His theory was disputed by other scientists and greeted with skepticism at the time. Only recently was it definitively proved to be an accurate theoretical analysis.

Auto Immune disorder
-
Hypersensitivity
