Which hummingbird has the best features to help it survive? A.hummingbird BB.hummingbird AC.both hummingbird A and BD.neither hummingbird A nor B4. green snakebrown snakeSnakes that live in green grassy areas tend to be green in color, and snakes that live in brown desert areas tend to be brown in color. How does this help the snakes survive? A.It allows the snake to feel more comfortable in its environment.B.It keeps the snake cool.C.It allows the snake to identify its relatives.D.It camouflages the snake, so it cannot be seen easily by predators or prey.5. Plants in the desert tend to have small, hard leaves that are coated to prevent water loss. Plants in the rainforest tend to have large leaves with pointed tips that slope down to promote water runoff.How have these leaf adaptations helped these plants to survive in their environment? A.The small leaves make it easier for the plant to survive in windy desert climates.B.The large leaves help provide shade for plants in sunny areas.C.The leaves help plants in dry places retain water and plants in wet areas repel water.D.The small leaves help the desert plants remain cool during hot summer days.6. Wild ducks often spend a lot of their time in the water. The ducks have special structures, called?_______,? that improve the ducks' ability to swim. A.wingsB.webbed feetC.feathersD.gills7. Maria visited the Chihuahuan desert in Mexico one summer. She observed that many animals, like the Gila monster pictured below, are seen moving around and eating only at dusk and dawn, or twilight.What could Maria infer about this behavior? A.All of the animals in the area feed on the same types of plants.B.None of the animals need very much water or food to survive.C.The animals are avoiding the hottest and coldest parts of the day.D.All of the animals in the area have brightly colored bodies.8. Vines are plants that can use other structures to grow. They can grow on most objects, such as rocks, buildings, and trees. Which of the following reasons best describes why the vine below is growing on the pole?A.to get as much sunlight as possibleB.to keep sunlight from the poleC.to reach the soilD.to get nutrients from the pole9. Owls are birds that sleep during the day and are active at night. Which of the owl's senses has changed to adapt to night conditions? A.sightB.tasteC.smellD.hearing10. How does a hummingbird's beak help it to meet its basic needs? A.The beak helps the bird to fly.B.The beak scares away predators.C.The beak allows the bird to eat the nectar out of flowers.D.The beak allows the bird to swim fast.Answers1. B 2. C 3. B 4. D 5. C 6. B 7. C 8. A 9. A 10. C Explanations1. Thick fur helps prevent heat loss from animals found in cold climates.2. Adaptations help animals and plants to survive in a particular environment. The big horn sheep is best adapted to live in a cold, rocky environment because it has thick woolly fur to help it stay warm and hooves that will not be hurt by walking on rocks.3. Because a hummingbird's food is deep within a flower, hummingbirds should have long, pointed beaks to be able to reach the nectar. If a hummingbird's beak is too short, like hummingbird B's, the bird won't be able to get enough food. Therefore, hummingbird A has the best features to help it survive.4. Animals, including some snakes, can blend into their environments. This is called camouflage. Predators have more difficulty spotting prey that is camouflaged. For example, a hawk would have more difficulty spotting a green snake lying on a patch of green grass than it would spotting a yellow snake lying on the same patch of grass.5. The structure of the plants' leaves are suited to their environments. The desert plants have small, hard leaves to retain water, which is so scarce in their environment. The rainforest plants have leaves to allow for water runoff so that the plants do not become waterlogged and rot.6. Ducks have webbed feet that help them move quickly through the water. This allows them to catch food, such as fish and insects.7. Only one answer can be inferred based on the information provided. The animals are avoiding the hottest and coldest parts of the day.Temperatures in the desert are the hottest in the middle of the day and can drop below freezing after sunset. Because of this, many animals hide in burrows during the middle of the day and at night.8. The pictured vine is growing upward on a pole. It is likely doing this to get as much sunlight as possible. The vine is growing upward, so it is not trying to reach soil. Also, the pole isn't living, so the vine cannot get nutrients from it and the pole does not require sunlight.9. Owls are active at night when it is dark. To adapt to dark conditions, the sight of owls is different than most birds'. Owls have very large eyes that are adapted to allow them to see clearly at night.10. A hummingbird's beak allows it to eat the nectar out of flowers. This helps the bird to meet its need for food. ................
