The diagram represents two solutions, A and B, separated by a selectively permeable membrane. A sample from solution A and solution B were each tested with blue-colored glucose indicator solution before the solutions were placed in the beaker. Which row represents the results?

• Row 1: Solution A: red/orange; Solution B: blue

• Row 2: Solution A: blue black; Solution B: amber

• Row 3 Solution A: blue; Solution B: red/orange

• Row 4: Solution A: amber; Solution B: blue black

Which statement best describes the outcome after 20 minutes?

• Solution A will contain approximately the same number of glucose molecules as solution B.

• Solution A will contain all of the water molecules.

• Solution B will remain unchanged.

• Solution B will lose all of the glucose molecules to solution A.

The chart below shows examples from two groups of organisms, multicellular and one-celled. The tissues and organs in group A perform functions that are

• similar to those performed by the tissues and organs in group B

• similar to those performed by the cell organelles in group B

• different from those performed by the tissues and organs in group B

• identical to those performed by the cell organelles in group B

The diagram below represents a specialized cell located in the root of a plant. The arrows in the diagram

indicate the movement of molecules of oxygen and water into the cell. Which row in the chart below correctly identifies the process responsible for the movement of each type

of molecules represented in the diagram?

• Row 1: Water: diffusion; Oxygen: active transport

• Row 2: Water: diffusion; Oxygen: diffusion

• Row 3: Water: active transport; Oxygen: diffusion

• Row 4: Water: active transport; Oxygen: active transport

Base your answers to the question on the diagram below, which represents a metabolic process, and on your knowledge of biology. This process best represents

• the bonding of amino acids to form a starch molecule

• the digestion of amino acids to form a starch molecule

• the bonding of simple sugars to form a starch molecule

• the digestion of simple sugars to form a starch molecule

Two biological processes that occur in certain organelles are represented in the diagrams below. Which statement is correct regarding the types of organisms able to carry out these processes?

• Process X occurs in heterotrophs, but not in autotrophs.

• Process Y occurs in consumers, but not in producers.

• Both processes X and Y occur in all living things.

• Both processes X and Y occur in green plants.
