Why do some plants produce fruit that contain seeds?
The fruit protects the seeds from animals that would eat them.

The Saguaro Cactus lives in the deserts of Arizona, southern California, and parts of
northern Mexico. They can grow to a height of over 70 feet and are covered in spines.
The roots of the Saguaro Cactus are shallow, only 4 to 6 inches deep and can spread
out as wide and the cactus is tall. Many desert bird species make holes in these cacti in
order to build their nests. The Saguaro cactus produces flowers in the spring that attract
bees, doves, and bats, who act as pollinators for the plant. The roots of the Saguaro Cactus are shallow and widely spread because ________ .
they need to absorb rainwater quickly before it evaporates
they prevent tall cactus from falling over in the strong desert wind
they can stabilize the cactus when birds dig holes in it to make nests
they cannot penetrate the hard desert rocks that lie just below the sand

The Arctic fox is a species of fox that lives throughout the Arctic tundra of the Northern
Hemisphere. Eating mostly Lemmings (small rodents), the Arctic fox uses its extremely
sensitive hearing to hunt its prey, even when it is hiding under the snow. When it is
winter the Arctic fox’s coat is white to blend in with its snow-covered surroundings. In the
summer, the coat changes to brown.
Which of the following characteristics of the Arctic fox is influenced by its
environment?
Arctic foxes hunt lemmings.
Arctic foxes live in tundra habitats.
Arctic foxes have very sensitive hearing.
Arctic foxes change color with the seasons.
Which of the following statements best supports the claim that some animal characteristics are inherited from their parents?
Bats have sensitive ears that help them hunt prey at night.
Warmer water temperatures cause some crustaceans to grow smaller.
Marine animals, such as sharks, show scarring from injuries while hunting.

Emperor Penguins are flightless, warm-blooded birds that live in the southern hemisphere, exclusively on the continent of Antarctica.

They have waterproof feathers, streamlined bodies, and a large amount of stored body fat. They have sleek feathers and strong, aerodynamic wings. What is the best explanation for why the Emperor Penguin have sleek feathers and
strong wings even though they cannot fly?
The wings are used to circulate blood so that the penguins do not overheat.
The wings are used to help the penguins balance on ice and help the them glide through the water.
The wings are left over from a time in the prehistoric past when penguins could fly.
The wings are used to help the penguins slide on the ice.

When fully adult, the tree frogs leave the the ponds where they lived as tadpoles, and spend their lives in the trees of their forest habitat. Their diet consists primarily of insects. Which of the following best explains why the red-eyed tree frog has green skin?
The green skin can be seen by other frogs and helps the frog attract a mate.
The green skin helps attract insects to the leaves where the frog can eat them.
