1.
Insects are animals.
Correct Answer
A. True
Explanation
Insects are a type of animal. They belong to the class Insecta, which is a diverse group of small, six-legged organisms. They have a hard exoskeleton, three body segments (head, thorax, and abdomen), and often have wings. Insects play important roles in ecosystems as pollinators, decomposers, and as a food source for other animals. Therefore, it is correct to say that insects are animals.
2.
Spiders are insects.
Correct Answer
B. False
Explanation
The statement is false because spiders are not insects. Spiders belong to a different class called Arachnida, while insects belong to the class Insecta. Spiders have eight legs and two body segments, while insects have six legs and three body segments. Therefore, spiders cannot be classified as insects.
3.
Insects account for ___ percent of all animals on the planet.
Correct Answer
D. 80%
Explanation
Insects account for 80% of all animals on the planet. This is because insects are the most diverse group of animals, with over a million known species. They are found in almost every habitat on Earth and play crucial roles in various ecosystems. Insects are important for pollination, decomposition, nutrient cycling, and as a food source for other animals. Their abundance and wide distribution contribute significantly to their high representation in the animal kingdom, making up the majority of animal species on the planet.
4.
What natural feature has had the greatest influence on insect size?
Correct Answer
B. AtmospHere
Explanation
The atmosphere has had the greatest influence on insect size. The composition of gases in the atmosphere, such as oxygen levels, can directly impact the size and development of insects. Insects rely on oxygen for their respiratory system, and higher oxygen levels in the atmosphere can support larger body sizes. Additionally, the atmospheric pressure and temperature can also affect insect growth and metabolism. Therefore, the atmosphere plays a crucial role in determining the size of insects.

How much honey will a single honey bee worker create in its lifetime?
Correct Answer
A. 1/12th of a teaspoon
Explanation
A single honey bee worker will create 1/12th of a teaspoon of honey in its lifetime. This is a small amount of honey considering the lifespan of a worker bee, which is typically around 6 weeks. Honey bees collect nectar from flowers and then process it in their bodies to produce honey. They store this honey in honeycomb cells within the hive, where it serves as a food source for the colony. The collective effort of many worker bees is required to produce significant quantities of honey.

What is the defining habit of Conicera tibialis, also known as the 'coffin fly'?
Correct Answer
B. Digging six feet deep in order to feed on buried human bodies
Explanation
Conicera tibialis, also known as the 'coffin fly', is known for its defining habit of digging six feet deep in order to feed on buried human bodies. This behavior sets it apart from other insects and is a unique characteristic of this species.
8.
Only male crickets chirp.
Correct Answer
A. True
Explanation
Male crickets chirp to attract females for mating. The sound is produced by rubbing their wings together, a behavior known as stridulation. Female crickets do not chirp because they do not need to attract mates. Instead, they listen for the male's chirping and respond to it. Therefore, it is true that only male crickets chirp.
9.
There are nearly as many species of ants as there are species of birds in the world.
Correct Answer
A. True
Explanation
The given statement is true. Ants are a highly diverse group of insects, with an estimated number of species ranging from 12,000 to 22,000. Birds, on the other hand, are also a diverse group with approximately 10,000 known species. While the exact numbers may vary, the statement is generally accurate in stating that there are nearly as many species of ants as there are species of birds in the world.
10.
Which of the following insects can live for several weeks without a head?
Correct Answer
C. Cockroach
Explanation
Cockroaches can live for several weeks without a head because they have an open circulatory system. Unlike humans, cockroaches do not rely on their heads for breathing, as they have tiny tubes called spiracles located all over their bodies. These spiracles allow them to take in oxygen directly, bypassing the need for a head. Additionally, cockroaches have a decentralized nervous system, with ganglia (clusters of nerve cells) distributed throughout their bodies. This allows them to continue functioning and moving even without a head.
