How is their investigation different from an experiment?

• They are not changing variables in the ecosystem.

• They hope to apply what they learn to produce something.

• They do not propose explanations based on their observations.

• They gather information without equipment and measurements.

How will black-footed ferret populations most likely be affected if a large number of prairie dogs die from the plague?

• The ferret population will increase because it will have fewer predators.

• The ferret population will decrease because there will be less food available.

• The ferret population will increase because the rabbit population will increase, providing more food.

• The ferret population will decrease because the fox population will increase, resulting in more predators.

• The spoon will get cooler because the coldness is transferred from the cold milk to the spoon.

• The spoon will get warmer because the coldness is transferred from the spoon to the cold milk.

• The spoon will get warmer because thermal energy is transferred from the cold milk to the spoon.

• The spoon will get cooler because thermal energy is transferred from the warm spoon to the cold milk.

Which statement best explains how poaching might have impacted the change in the proportion of elephants born without tusks?

• Being born without tusks was a disadvantage for the survival of elephants during the poaching period, so elephants without tusks were less likely to survive and reproduce.

• Being born without tusks was an advantage for the survival of elephants during the poaching period, so elephants without tusks were more likely to survive and reproduce.

• Being born without tusks became less of a disadvantage for the survival of elephants during the poaching period, so elephants without tusks had slightly more likelihood of reproducing.

• Being born with or without tusks had no impact on the likelihood that an elephant would survive and reproduce during the poaching period.
