• 1, 2, 3, 4

• 2, 1, 3, 4

• 4, 2, 3, 1

• 3, 4, 1, 2

Which observations show the frog interacting with nonliving elements in its environment?

• A. 1 and 4

• B. 2 and 5

• C. 3 and 6

• D. 1 and 6

Which two traits BEST help a cactus conserve water in the dry conditions of a West Texas ecosystem?

• large flowers and sweet fruit

• sweet fruit and sharp spines

• sharp spines and waxy stems

• waxy stems and large flowers

Fox squirrels live in the trees in cities throughout Texas. Each spring they build nests of twigs and leaves in the tops of the trees. Fox squirrels are often found near park benches, waiting to be fed by visitors. 

For fox squirrels, which of these is a learned behavior?

• building a nest each spring

• taking food from people

• having a long, bushy tail

• having sharp claws

The whiskers of a river otter and the antenna of a cockroach are shown below. 

How do structures such as whiskers and antennae benefit organisms?

• They help the organisms detect their surroundings.

• They help the organisms eat food quickly.

• They help the organisms fight predators.

• None of the above.

Students study barracudas. They make observations and gather some information on barracudas. Which observation describes barracudas interacting with the biotic elements of their ecosystem?

• A. Barracudas can travel quickly using the surface ocean currents.

• B. Barracudas live around hard structures such as oil rigs and jetties.

• C. Barracudas are predators of other fish.

• D. Barracudas tend to live in warm waters.

The shells of sea turtles are flatter than the shells of land turtles. Sea turtles are also different from land turtles because sea turtles cannot pull their head or limbs into their shells to protect themselves from predators. Instead, the head, shell shape, and flippers of sea turtles help them escape from predators mainly by allowing them to

• dig deep holes for their eggs

• swim and dive easily

• blend into their surroundings

• hold their breath for several minutes

A farmer keeps bees to pollinate crops. The farmer makes several observations about the bees. Which of these observations describes a learned behavior?

• Bees make return trips to drink sugar water from a bowl.

• Bees have dark eyes and black-and-yellow stripes.

• Bees produce honey from the nectar they collect.

• Bees will sting when threatened or disturbed.

The life cycle of a beetle and a bean plant are shown below. The same stage in both life cycles is the initial stage (egg for the beetle and seed for the bean plant). Which stage is the same in both?

• Egg/Seed stage

• Larva/Sprout stage

• Pupa/Sapling stage

• Adult/Flowering stage

Newly hatched chicks of many types of birds, such as parrots, are covered in soft, fluffy down feathers. These feathers contain many small spaces where air gets trapped. In some animal species, such as Arctic foxes, the fur covering the animal’s body consists of hollow strands of hair filled with air. The primary role of the air trapped in the down feathers and fur is MOST LIKELY to - 

• act as a cushion to prevent injuries from falls

• decrease the amount of energy needed for running or flying

• provide a layer of insulation to help control body temperature

• supply oxygen to be absorbed through the skin for transport to the lungs
