Biology of Insects and Pollination Questions
-
cricket
-
mosquito
-
spider
-
honeybee
A
Correct answer
Explanation
Crickets are known for their ability to indicate air temperature through their chirping rate. As crickets are cold-blooded, their muscle contractions for chirping depend on ambient temperature. Dolbear's Law states that you can calculate the temperature in Fahrenheit by counting the number of cricket chirps in 14 seconds and adding 40.
-
Egg of silkworm
-
Larva of silkworm
-
Pupa of silkworm
-
Insect itself
B
Correct answer
Explanation
Silk is produced by the larva of the silkworm (Bombyx mori). The caterpillar secretes silk fibroin from glands to form its cocoon during the pupal stage. The larva spins the cocoon before becoming a pupa.
C
Correct answer
Explanation
Butterflies have taste receptors (chemosensors) located on their feet (tarsi). When they land on a plant or food source, they 'taste' it by pressing their feet against the surface to determine if it's suitable for feeding or egg-laying. This adaptation makes sense for their feeding behavior.
-
Housefly
-
Firefly
-
Sandfly
-
Fruitfly
B
Correct answer
Explanation
Fireflies produce light through bioluminescence using the chemical luciferin. When luciferin reacts with oxygen in the presence of the enzyme luciferase, light is produced. This is used for mate attraction and communication.
C
Correct answer
Explanation
Bees have two pairs of wings (four wings total). The forewings and hindwings hook together during flight to function as a single surface, providing excellent maneuverability.
-
a hundred insects
-
a thousand insects
-
200 million insects
-
No insects
C
Correct answer
Explanation
Scientists estimate that for every human on Earth, there are approximately 200 million insects when considering total insect biomass divided by human population. This represents global ratios, not insects physically near each person.
-
steep
-
disgust
-
a place where bees are kept
-
of sound or its speed in air
C
Correct answer
Explanation
An apiary is a place where bees are kept - a bee yard or collection of beehives maintained by a beekeeper. The other options refer to: steep (A), disgust (B), and acoustic (D).
-
exact
-
reject with rudeness or coldness (an offer or friendship)
-
bee-keeping
-
14-line poetic verse form with a fixed rhyme pattern
C
Correct answer
Explanation
Apiculture means beekeeping - the practice of maintaining honeybee colonies for honey, wax, or pollination. The other options refer to: precise (A), rebuff (B), and sonnet (D).
-
large group of insects moving in a mass
-
acquire
-
force into less space
-
play or frolic boisterously
C
Correct answer
Explanation
Compress means to press or squeeze something into less space or a smaller volume. Option C correctly defines this as forcing something into less space. The other options describe unrelated concepts: a swarm of insects (A), acquiring something (B), or playing energetically (D).
-
study of insects
-
climb by crawling with difficulties
-
active strength
-
law enacted by the legislature
A
Correct answer
Explanation
Entomology is the scientific study of insects, a branch of zoology. It comes from Greek 'entomon' (insect) and 'logia' (study of). The other options are incorrect: crawling with difficulty describes scrabbling, active strength is vigor, and a law passed by legislature is a statute or act.
-
an insect
-
a microbe
-
a plant
-
a pest
C
Correct answer
Explanation
Aloe is a succulent plant species, widely cultivated for its medicinal and ornamental uses. It is definitely a plant, not an insect, microbe, or pest. Aloe vera gel is commonly used for skin care and treating burns.
-

-
Throng : Person
-

A swarm is a large group of insects. Similarly, a throng is a large crowd or group of people. The relationship is collective group : individual organism. Option D is parent-offspring, not group-individual. Option A is event-participant.
-
a place to keep bees
-
a place to keep cat
-
a place to keep bird
-
a place to keep ant
A
Correct answer
Explanation
An apiary is a place where bees are kept, specifically a collection of beehives. Option A 'a place to keep bees' is correct. The other options incorrectly substitute cats, birds, and ants for bees, which are not the intended meaning of apiary.
-
Important.
-
Red ant.
-
Black ant
-
Extravagant.
A
Correct answer
Explanation
This is a phonetic wordplay riddle. When spoken quickly, "foreign ant" sounds like "important" (for-eign-ant → im-por-tant). This type of riddle relies on similar-sounding phrases rather than literal meaning. The other options (red ant, black ant, extravagant) are literal interpretations that miss the wordplay.
-
deeryclostagnos
-
agnosdelano
-
agnosvitriblunin
-
trymuttiagnos
C
Correct answer
Explanation
Analyzing the patterns: agnos means spider (appears in both spider terms), crenia/crenia indicates poisonous, and deery means brown. For 'black widow spider', we need the spider root 'agnos' plus a term for black widow. Option C provides 'agnosvitriblunin' which logically combines spider (agnos) with black widow (vitriblunin). The other options either reverse the order or use incorrect roots.
