Science review Qtr2

The Florida scrub jay is a bird found only in the scrub habitat of Central Florida. Efforts are being made in Florida to preserve the scrub habitat by limiting development by humans and maintaining natural conditions. Which may occur over time if the Florida scrub habitat is NOT preserved?

• The scrub jays may become extinct.

• The scrub jays may move to live in a coastal habitat.

• The scrub jays may learn to live in any habitat that replaces the scrub habitat.

• The scrub jays may have offspring with changed features to match a new habitat.

Mosquitoes have short life cycles based on the temperature and the amount of daylight. With increased global temperatures, a species of mosquito is beginning to reproduce earlier in the year as well as entering dormancy later in the year. Which phrase describes this change in the life cycle of the mosquito?

• a species losing habitat

• a species overpopulating

• a species adapting to changes in an environment

• a species gaining a competitive advantage over predators

In an experiment about learning, a scientist sent five rats through a maze and recorded the time for each to finish the maze. Then the scientist sent each rat through the same maze a second time, again recording the time to finish. Which statement is based on direct evidence the scientist likely made during this experiment?

• Rats going through the maze a third time will probably finish in less time than before.

• Rats going through the maze the first time averaged 10 seconds more than the second time.

• Rats going through the maze were distracted by noises in the hall, which increased the time to finish the maze.

• Rats going through the maze will be motivated by food at the end, and the rats will finish in less time than if there were no food.

How do the waxy stem covering and needle-shaped leaves improve the ability of a cactus to survive in the desert?

• They make the plant appetizing to small desert animals.

• They prevent the loss of oxygen through photosynthesis.

• They reduce the loss of water from the plant to the air.
