A type of cellular transport is shown.

Which description best identifies this type of cellular transport?

• Active transport, because energy is being used to move molecules against the concentration gradient

• 
  Facilitated diffusion, because energy is being used to move molecules with the concentration gradient

• Osmosis, because energy is not being used to move molecules with the concentration gradient

• Endocytosis, because energy is not being used to move molecules against the concentration gradient

Which of these must occur during S phase of the cell cycle so that two daughter cells can be produced during M phase?

• The DNA must be replicated.

• The chromosomes must be joined.

• The cytoplasm must be separated.

• The cell membrane must be expanded.

The diagram shows cells in different phases of mitosis. A student is trying to find a cell in a particular phase of mitosis. The student is looking for evidence that spindle fibers are separating the chromosomes to ensure that each new nucleus has one copy of each chromosome.

• Cell 1

• Cell 2

• Cell 3

• Cell 4

• Toothed whales are more closely related to mouse deer than to hippopotamuses.

• Javelinas and pigs are more closely related than baleen whales and toothed whales.

• Javelinas and pigs are more closely related than baleen whales and toothed whales.

A new predator of rabbits has been introduced within an ecosystem. This new predator runs faster than the native predators of rabbits.
​
​Which statement describes what will most likely occur in the rabbit population due to the introduction of the predator?

• The rabbits will mutate their genes and express genes that increase their speed.

• Slower rabbits will develop stronger legs and pass this trait to their offspring.

• Rabbits will mate and produce offspring with a different species that has faster runners.

• Faster rabbits will survive and reproduce increasing the average speed of the rabbit population.
