• The ability of the caterpillars to eat toxic leaves without being harmed

• The number of milkweed leaves the caterpillars eat each day

• The number of leaves on the milkweed plants that the caterpillars visit each summer

TEKS 5.10B 2014-Q30:

TEKS 5.10B 2013-Q13:

Fox squirrels live in the trees of city parks 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

TEKS 5.10B 2013-Q19:

A scientist observes sea otters using rocks to break open clamshells.
