April 20 EOC Review 4

Abby notices that the lettuce in a salad wilts soon after salt is added. Wilting most likely occurs because the lettuce cells

• swell when exposed to salt

• absorb the extra salt

• release water in the presence of salt

• lose oxygen when in contact with salt

The diagram below shows the feeding relationships for four coral reef organisms.

Humans sometimes kill giant tritons in order to collect their attractive spiral shells.

If humans kill most of the giant tritons in a coral reef, the coral population will most likely

• decrease due to a decrease in the parrot fish population

• increase due to an increase in the parrot fish population

• increase due to a decrease in the crown-of-thorns sea star population

• decrease due to a increase in the crown-of-thorns sea star population

• mitosis

• coordination

• recombination

In some parts of the world, forests are being cut down and burned to clear land for new homes and new farmland. A negative effect of these activities might be

• An increase in global warming

• destruction of the ozone shield

• a decrease in the average temperature of the atmosphere

• an increase in biodiversity of the deforested areas

Which statement explains the importance of maintaining a constant internal environment to ensure proper enzyme functioning?

• Changes in pH and temperature will cause the enzyme reaction rate to be too fast.

In the cells of the human body, oxygen molecules are used directly in a process that

• releases energy

• digests fats

• synthesizes carbohydrate molecules

• alters the genetic traits of the cells

Sexually reproduced offspring have traits similar to their parents because they receive

• All the proteins from each parent

• Some of the proteins from both parents

• All of the genes present in both parents

• Some of the genes present in each parent

Which statement best describes the interactions between the structures found within a single-celled organism?

• They allow the organism to maintain homeostasis.

• They prevent homeostasis from damaging the cell.

• They must act independently of each other and prevent homeostasis.

• They carry out the same life process to maintain homeostasis.
