​Which two traits best help a cactus conserve water in the dry conditions of a West Texas desert ecosystem?
Sweet fruit and sharp spines

​The ocotillo is a desert plant with long, straight branches. Its leaves are small and appear for only a short time after a rain. Most of the time, the branches of the ocotillo do not have leaves. Maple trees grow in areas where water is more abundant than in the desert. Maple leaves can be very large and are present for most months of the year. Ocotillo plants are better adapted for surviving in the desert than maple trees because the characteristics of ocotillo leaves —
prevent the plant from producing flowers
encourage the release of carbon dioxide from the stems
reduce the amount of water lost through evaporation
allow more sunlight to reach the soil

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?
A scientist observes sea otters using rocks to break open clamshells. Which of these investigations would best help the scientist determine whether this skill is a learned or an inherited behavior?
Crayfish live in water and often hide under rocks or plants. They come out to look for food and will eat both plants and animals. Which of these is a trait that a crayfish most likely inherits from its parents?
The caterpillars of monarch butterflies eat milkweed leaves. Milkweed leaves contain sap that is toxic to many animals but not to monarch butterfly caterpillars. This sap makes the monarch butterfly caterpillars toxic to predators and protects them from being eaten. Which of these is an inherited trait of monarch butterfly caterpillars?
Which of these is a learned behavior of a dog?
