What would likely occur in this food web if the grasshoppers (circled) were wiped out by disease?

• Spiders would adapt to fill the open niche.

• There would be less plants as other animals consumed plants instead of grasshoppers.

Which of the following best explains the relationship between structures X and Y?

• X, chromosomes, are located inside Y, the nucleus, and these structures store genetic material for the cell.

• X, the nucleus, is located inside Y, chromosomes, and these structures provide energy for the cell.

• X, ribosomes, are located inside Y, the nucleus, and these structures provide protection for the cell.

• X, chromosomes, is located inside Y, DNA, and these structures store proteins for the cell.

• To control conscious and unconscious actions to maintain a body's homeostasis

• To produce strong muscles that store energy for long term movements

• To protect the heart and other other organs from potentially damaging impacts

• To absorb light and then use it to trigger responses in the biceps and heart

Many scientists believe that whales actually evolved from a dog-like ancestor. The picture shows a possible progression of changes that occurred over millions of years. Which of the following environmental pressures could have driven this change?

• As temperatures on land increased, animals spent more time in the water.

• It was difficult for organisms to find a mate on land.

• A decrease in the amount of food available on land drove animals to hunt for prey in the water.

• Other predators preyed on the whale's ancestor, so it was safer for them in the water.

The northern spotted owl is a nonmigratory species found throughout Washington, Oregon, and California. They prefer to nest in old-growth forests, which are ancient forests mostly untouched by outside influences. They are very territorial and do not like disturbances to their habitats. Their diet consists mainly of flying squirrels, wood rats, and other small rodents and insects found in tree canopies.

Based on this information, which of the following would not directly limit the population size of the northern spotted owl?

• The availability of nesting sites

• The amount of sunlight

• The number of rodents

• The number of trees
