/ A. / tundra/ B. / desert
/ C. / rainforest
/ D. / savanna
5. All seed plants have roots. Which of the following does NOT describe a function of a plant's root system?
/ A. / change energy from the sun into food/ B. / store water and nutrients
/ C. / anchor the plant to the ground
/ D. / absorb water and nutrients from the soil
6. Plants are able to support themselves in an upright position due to turgor pressure. Water maintains the turgor pressure in stems like air inflates a balloon. Which of the following body systems helps humans to support themselves?
/ A. / digestive/ B. / skeletal
/ C. / circulatory
/ D. / lymphatic
7. The harp seal lives on the polar ice sheets. Which adaptation makes it best suited for this environment?
/ A. / ears/ B. / whiskers

/ A. / a mutation./ B. / an adaptation.
/ C. / extinction.
/ D. / natural selection.
9. While visiting the Galapagos Islands, Charles Darwin noticed several species of birds, which he called finches. These finches were similar in some ways but different in others.
Some of the finches that Charles Darwin observed on the Galapagos Islands fed on tiny insect parasites living on the skin of tortoises and lizards. These finches would reach their beaks into small, narrow folds in the animals' skin to catch their insect prey. Which finch below most likely fed on the smallest insects?
/ B. / finch X
/ C. / finch Y
/ D. / finch Z
10. Living organisms have different structures that enable them to function effectively in specific ways. Which foot below belongs to a beaver?
/ A. / Y/ B. / W
/ C. / X
/ D. / Z
11. The picture below shows a jellyfish.
In which of the following ways does a jellyfish obtain food?
/ B. / It makes food using carbon dioxide and sunlight.
/ C. / It absorbs chemicals found in sea water.
/ D. / It scoops prey up with its bell.
12. The development of a structure containing many sensory tissues and organs was a major evolutionary development in animals. This structure faces the direction in which the organism moves, allowing the organism to sense the environment before moving toward it.
What is the structure developed to help organisms sense their surroundings?
/ B. / head
/ C. / tail
/ D. / skin
13. Examine the picture of the beaver below.
BR>
Beavers use log dams for shelter. They build their dams over ponds, creeks, and rivers. What structure does a beaver use to cut down trees used to build its dam?
/ B. / its claws
/ C. / its teeth
/ D. / its scales
14.
This bird’s feet are most adapted to
/ A. / swim easily through the water./ B. / climb high into the trees.
/ C. / catch and kill prey.
/ D. / run quickly across the ground.
15.
Look at the fish above. They have probably adapted to have different fin shapes and locations because
/ B. / it helps the fish to have more friends.
/ C. / it helps the fish to survive in their environment.
/ D. / it helps the fish attract more predators.
16. The giraffe’s neck has adapted to its environment. In what way has this helped it to survive?
/ A. / It helps it run faster./ B. / It helps it hide from predators.
/ C. / It helps it tolerate warm temperatures.
/ D. / It helps it to reach food high in the trees.

/ B. / nectar
/ C. / seeds
/ D. / fish
18. What is an important function of a giraffe's extremely long neck?
/ A. / It allows the giraffe to eat the leaves off tall trees./ B. / It has no useful function.
/ C. / It allows the giraffe to see predators that are a long way away.
/ D. / It intimidates predators of the giraffe.
19. Both animals and plants require energy to perform their daily life functions. Animals generally consume food and drink water through their mouths to gain energy. Which plant structure most similarly serves the function of a mouth?
/ A. / stem/ B. / flowers
/ C. / roots
/ D. / leaves

What is the function of the male peacock's train?
/ B. / It attracts female peacocks.
/ C. / It scares away predators.
/ D. / It is used to help the peacock swim in water.
