If a cell's plasma (cell) membrane stopped working, which of the following would be a logical conclusion?

• The cell would not be able to make proteins.
• The cell would not be able to regulate materials coming in and out of the cell.
• The cell would not be able to sort and package proteins so they can be shipped out of the cell.
• The cell would not be able to carry out cellular respiration.

Which means of particle transport is shown in the figure below?

• diffusion
• osmosis
• facilitated diffusion
• active transport

Which of the following statements best describes an organism’s attempt to maintain CELLULAR homeostasis?

• a flowering plant bends towards the light
• a paramecium’s vacuole expels (gets rid of) excess water from a cell.
• a wren lays three eggs in its nest
• a pup growls when a litter mate attempts to take its bone.
• an earthworm’s DNA is replicated

At the end of the cell cycle, how many chromosomes will each daughter cell?

• During DNA replication, the number of chromosomes is cut in half.
• During DNA replication, the number of chromosomes stays the same.
• During cell division, each daughter cell will get the same number of chromosomes/genes.
• During cell division, each daughter cell will get a random number of chromosomes/genes.

A multicellular organism begins life as a single cell — a fertilized egg with a complete set of chromosomes. The picture below shows how the cell divides to become two cells, then four cells, eight cells, and so on. Which of the following statements best describes what happens during this process?

• Chromosomes are duplicated before cell division so that each new daughter cell has a complete set.
• Chromosomes are divided evenly during cell division so that each new daughter cell has an equal share (half) of the original set.
• Chromosomes are stored in the original cell to direct the division of all daughter cells, which do not have their own chromosomes.
• Chromosomes are randomly distributed during cell division so that some new cells have partial sets while others have complete sets.
