Molecule A cannot diffuse. What is a possible reason why?

• Molecule A is a macromolecule and it is too large to move.

• Molecule A is a building block and it is too large to move.

• Molecule A is a building block and it is too small to move.

• Molecule A is a macromole and it is too small to move.

What is the starch indicator?

• Iodine

• Bromothymol Blue

• Benedict's Solution

• Glucose

Cell membranes are said to be selectively permeable. Which statement best explains what selectively permeable means?

• The cell membrane prevents any harmful substance from entering the cell.

• The cell membrane lets certain substances enter the cell and keeps certain substances out of the cell.

• The cell membrane allows only large molecules to diffuse into the cell.

• The cell membrane has pores that let only water and glucose into the cell and carbon dioxide out.
