Question 1
Which statement accurately describes desert locusts?
Correct Answer:
They can form swarms that cause significant agricultural damage.
Explanation:
Desert locusts can switch from solitary individuals to large, swarming groups when conditions favor rapid population growth. In the swarming phase they form dense, traveling bands that can cover huge distances and strip crops bare in a short time. That combination of coordinated movement and enormous feeding pressure is what makes their swarms so damaging to agriculture, so the statement describing them as capable of forming swarms that cause significant agricultural damage is the best fit. They are not typically solitary, they don’t migrate only at night, and they feed on plant material, not non-plant matter.
Question 2
Which statement best defines camouflage?
Correct Answer:
The ability of an animal to blend in with its surroundings to avoid detection.
Explanation:
Camouflage is an adaptation that helps an animal go unseen by blending into its surroundings. By matching color, pattern, texture, or even behavior to the background, the organism becomes harder to detect by predators or to alert prey. This blending-in ability is what lets camouflage do its job—concealment through resemblance to the environment. The other ideas describe migration, producing light to lure prey, or growing armor, none of which capture the concealment and blending aspect that camouflage specifically refers to.
Question 3
What is notable about the Chinese giant salamander?
Correct Answer:
It is the largest amphibian and is critically endangered due to habitat loss and overexploitation.
Explanation:
The main idea here is that this salamander stands out as the largest amphibian on Earth, capable of reaching lengths close to a meter and a half to nearly two meters. That enormous size is paired with a troubling conservation status: it is critically endangered because its freshwater habitats in China are being lost or degraded, and the animals are heavily collected for food and for the pet trade. Pollution, dam construction, and habitat fragmentation further threaten populations. This combination of extreme size and severe threat makes it particularly notable. It’s not venomous, so that option isn’t correct.
Question 4
Which migratory pattern describes species that spawn in freshwater after maturing in saltwater?
Correct Answer:
Anadromous
Explanation:
Anadromous describes a life cycle in which species grow up in saltwater and then migrate into freshwater to spawn. This matches the idea of maturing in the ocean and returning to freshwater to reproduce, as seen in salmon. The other terms don’t describe this migratory pattern: catadromous is the reverse—mature in freshwater and spawn in saltwater; oviparous and viviparous refer to egg-laying and live birth, not migration.
Question 5
Which statement best describes a feature of the Golden Eagle?
Correct Answer:
An impressive wingspan and soaring flight.
Explanation:
Large wingspan enabling soaring flight is a defining feature of the Golden Eagle. Those broad, elongated wings let the bird ride thermals and glide for long periods with minimal flapping, which helps it cover vast territories while scanning for prey from above. The plumage is not bright; the tail isn’t extremely short, and while it can rise and circle in the sky, its hunting style is powered and versatile, not just a slow glide. So the best description is its impressive wingspan and soaring flight.
