Biology of Insects and Pollination Questions
-
Natural pearls that are perfectly spherical
-
Cultured pearls with spherical shape
-
None of these
-
Natural pearls with the most unusual shapes
A
Correct answer
Explanation
Natural pearls that form perfectly spherical without human intervention are extremely rare and therefore the most valuable. Cultured pearls are intentionally created by humans, while irregular natural pearls lack the premium that perfect symmetry commands.
-
Pollination through wind
-
Pollination through birds
-
Pollination by insects
-
Dispersal of seeds by wind
B
Correct answer
Explanation
Ornithophily specifically refers to pollination by birds. The term comes from 'ornis' (bird) and 'phily' (love). Wind pollination is anemophily, insect pollination is entomophily, and seed dispersal by wind is anemochory. Birds like sunbirds and hummingbirds are common pollinators.
B
Correct answer
Explanation
According to CDC and allergy organization data, approximately 100-150 Americans die annually from anaphylactic reactions to stinging insect venom (bees, wasps, hornets, fire ants). The 150 figure represents the upper end of documented fatalities from these severe allergic reactions. Lower numbers underestimate the actual public health impact, while higher numbers are unsubstantiated.
-
A dry protein from trees, grass, flower, weeds.
-
A heavy, waxy substance carried by flying insects.
-
A grainy, potent, histamine-producing allergy trigger.
-
All of the Above
B
Correct answer
Explanation
Mosquitoes are actually attracted to carbon dioxide, heat, and certain skin odors, as well as dark colors like black or navy. There is no scientific basis for them being attracted to blue twice as much as other colors.
A
Correct answer
Explanation
A group of anacondas is specifically called a bed or a knot. This is the correct collective noun for these snakes.
-
mating Bucket
-
Breed Ball
-
Mating Ground
-
Mating Ball
D
Correct answer
Explanation
A 'mating ball' is a biological phenomenon, particularly common in snakes like garter snakes and anacondas, where multiple males swarm a single receptive female in an attempt to mate. The other terms are not standard biological terminology for this behavior.
-
infant
-
Wriggler
-
flapper
-
foal
B
Correct answer
Explanation
A young mosquito in aquatic larval stage is called a wriggler. They actively wriggle/swim in water. An infant is a human baby, a flapper is not a mosquito stage, and a foal is a young horse.
-
male moths
-
female moths
-
caterpillar
-
female bugs
A
Correct answer
Explanation
Pheromone traps use synthetic female sex pheromones to attract and trap male moths, disrupting their mating cycle. This is a key biological pest control method in agriculture because it specifically targets the male population without using chemical insecticides.
-
wings
-
voice
-
legs
-
none of he above
A
Correct answer
Explanation
The buzzing sound produced by bees, mosquitoes, and similar insects is created by the extremely rapid vibration of their wings as they fly. This wing-beat frequency can range from hundreds to thousands of times per second, creating the characteristic humming or buzzing noise we hear.
-
INCAPACITATING BITE
-
INSATIABLE HUNGER
-
SPAWN SPIDERLINGS
-
SPAWN WEB
A
Correct answer
Explanation
Incapacitating Bite was Broodmother's orb effect in Dota 2 - a unique attack modifier that applied a slow and miss chance on attacks. Orb effects were unique modifiers that didn't stack with each other. Insatiable Hunger is a lifesteal ability, Spawn Spiderlings creates units, and Spawn Web creates terrain.

Insectaphobia
-
Insectphobia
-
Insectophobia
-
Insectephobia
C
Correct answer
Explanation
Insectophobia is the correct term for fear of insects, combining 'insect' with '-phobia' (fear). This follows standard medical terminology rules. The other options incorrectly insert or omit letters: Insectaphobia adds an extra 'a', Insectphobia omits the connecting vowel, and Insectephobia adds an unnecessary 'e'.
B
Correct answer
Explanation
While many ant species can sting, not all ants have this capability. Some ants rely primarily on biting, spraying formic acid, or other defense mechanisms instead of stinging. For example, many ponerine ants lack stingers and use their powerful mandibles or chemical defenses for protection.
A
Correct answer
Explanation
Some caterpillar species, particularly certain butterfly and moth caterpillars, are predatory and do eat ants. The caterpillars of some lycaenid butterflies and certain moth species are known to be carnivorous, feeding on ants. Some use chemical mimicry to trick ants into becoming their prey, while others actively hunt ants.
