Which of the following best explains the process illustrated in the above diagram?

• Passage of water molecules through a semi-permeable membrane to equalize concentration

• Transport of molecules across a membrane from a high to low concentration gradient by means of a carrier molecule

• Movement of molecules against a concentration gradient expending energy

• Separation of suspended particles from a fluid environment to a non-fluid environment through a porous membrane

A scientist is investigating cell transport. She observes molecules being transported into a cell through proteins present in the cell membrane. These proteins do not use energy to transport the molecules. Which of the following best explains the type of cell transport observed by the scientist?

• Active transport because membrane proteins were used

• Diffusion because the molecules were entering the cell

• Facilitated diffusion because the proteins were not using energy

• Osmosis because the molecules were moving against the concentration gradient

4B: Some students used vinegar to dissolve away the shells of three eggs and used these eggs as models of human red blood cells. The students observed the changes in the eggs when they were placed in different solutions. Which statement best describes the role of the cell membrane in this model?

• The cell membrane is an impermeable barrier that prevents water from entering the cell.

• The cell membrane allows solutes to enter the cell, which causes the cell to shrink

• The cell membrane allows water to enter and leave the cell

• The cell membrane removes solutes from the environment

Which term describes the process illustrated in the diagram?

• Sexual reproduction

• Viral reproduction

• Mitotic reproduction

• Meiotic reproduction

4C: In the 1880s, Louis Pasteur developed a method for weakening viruses. The weakened viruses could be injected into healthy individuals. How is this method effective in fighting viral disease?

• The immune system develops antibodies in response to the weakened viruses.

• The weakened viruses attach to unaffected viruses in the host and interrupt the viral reproductive cycle

• The rate of genetic mutation in the host is decreased due to the introduction of weakened viruses

• Weakening viruses are unable to enter the host organism

An anticancer drug stops a cancer cell from dividing after the 2nd checkpoint. During which stage is the drug most effective in the cell cycle?

• Gap 1 (G1)

• Synthesis (S)

• Gap 2 (G2)

• Mitosis (M)

A diagram of cells in various stages of mitosis is pictured below in random order. Which is occurring within the cell labeled II?

• A cleavage furrow is forming to divide the cell into two daughter cells.

• DNA is replicated so there are two copies of each chromosome in each daughter cell.

• Chromatin is condensing to form visible chromosomes.

• The spindle is attaching to chromatids to move them to the middle.
