1. A small land animal has eight legs, two main body regions, and no antennae. To which group does it belong?
Insects
Centipedes
Crustaceans

2. Coral may resemble a colorful underwater plant, but what is it primarily composed of?
Marine plants with mineral-coated leaves
Fungi growing on submerged rock
Colonies of small animals called polyps
Single shelled mollusks joined together
3. A whale repeatedly rises to the ocean surface and exposes its blowhole. What essential need is it meeting?
Breathing atmospheric air into its lungs
Finding floating food with its blowhole
Removing salt through its lungs
Cooling its blood with surface water
4. In a woodland, a sharp decline in insects occurs during the nesting season. What is the most immediate likely pressure on insect-eating birds?
They lose the ability to build nests in trees.
They have less food available for themselves and their chicks.
Their feathers stop providing insulation.
They become unable to recognize predators.
5. A bat emits high-frequency calls while flying through a dark cave. How do these calls help it navigate?
They create a magnetic field that points toward the cave exit.
They produce electrical signals sensed by nearby rock.
They cause insects to glow briefly in the dark.
Their echoes reveal the distance and position of surrounding objects.
6. Which anatomical feature separates sharks from most familiar bony fish?
Sharks have gills, while bony fish use lungs exclusively.
Shark skeletons are mainly cartilage rather than bone.
Sharks lack fins, while bony fish use fins for movement.
Sharks are warm-blooded mammals, while bony fish are reptiles.
7. A lizard sits on a sun-warmed rock early in the morning. What is the most likely reason for this behavior?
It is raising its body temperature using an external heat source.
It is producing extra body heat through rapid internal metabolism.
It is absorbing sunlight to make food through photosynthesis.
It is preparing to breathe through its skin for the rest of the day.
8. Which feature most clearly distinguishes mammals from all other living vertebrate groups?
Females produce milk to nourish their young.
They maintain a relatively stable internal body temperature.
They give birth to live young.
They have four limbs at some stage of development.
9. A bee carries pollen from the anther of one flower to the stigma of another flower of the same species. What process is it assisting?
Seed dispersal
Germination
Pollination
Decomposition
10. Which statement correctly compares the natural distributions of penguins and polar bears?

Both are native to Antarctica.
Penguins are Arctic animals, while polar bears are Antarctic animals.
Penguins occur mainly in the Southern Hemisphere, while polar bears are native to the Arctic.
11. A bird population travels between distant breeding and feeding grounds at predictable times of year. What is this behavior called?
Hibernation
Migration
Metamorphosis
Echolocation
12. What is the main function of a fish's gills?
Producing body heat in cold water
Controlling movement by pushing against the water
Transferring dissolved oxygen from water into the bloodstream
Detecting light below the water's surface
13. A wetland where frogs breed loses most of its shallow freshwater pools. Which consequence is most direct?
Adult frogs can no longer regulate body heat internally.
Fewer suitable places remain for their unshelled eggs and aquatic young.
Young frogs will hatch with feathers instead of moist skin.
Adult frogs will permanently switch from lungs to gills.
14. A harmless hoverfly has yellow-and-black markings that make it resemble a stinging wasp. Which defensive strategy is this?
Mimicry
Seasonal molting
Camouflage
Territorial display
15. After a caterpillar finishes its main feeding and growth stage, which stage normally comes next in a butterfly's complete metamorphosis?
Egg
Nymph
Adult
Pupa
16. An owl must approach prey without producing much wing noise. Which adaptation contributes most directly to this ability?
Down feathers that retain body heat
Broad wings that allow soaring
Fringed flight-feather edges that disrupt airflow quietly
Hollow bones that reduce body weight
