Biology of Insects and Pollination Questions
C
Correct answer
Explanation
Female mosquitoes require blood as a protein source to develop their eggs. Male mosquitoes feed only on nectar and plant sugars, but females need the additional nutrients from blood for reproduction. This blood-feeding behavior is also why female mosquitoes are the ones that transmit diseases like malaria and dengue.
-
cricket
-
mosquito
-
spider
-
beatle
A
Correct answer
Explanation
Crickets can accurately indicate air temperature through their chirping rate - cricket chirps increase predictably with temperature. This relationship is so reliable that you can calculate temperature in Fahrenheit by counting chirps in 14 seconds and adding 40.
-
barklice
-
beetles
-
flies
-
honey bees
D
Correct answer
Explanation
Honey bees do indeed have hair-like structures called setae on their eyes. These microscopic hairs serve various functions including detecting wind direction, sensing pollen, and helping with navigation. The eye hairs are part of the bee's exoskeleton and are visible under magnification.
-
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.
-
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.
