Giancarlo sets up 5 test tubes: pH 3, pH 5, pH 7, pH 9, and pH 11. Each test tube has 50 g of the pH buffer solution, 10 g of the enzyme DNA polymerase, and 50 g of the enzyme's substrates (a short piece of a DNA chromosome and free RNA nucleotides). He measures the activity rate of DNA polymerase in each test tube by measuring how many copies of the DNA chromosome it produces as products of its reaction. Which statement BEST describes the components of Giancarlo's experiment?

The blue particles in this image are able to cross the cell membrane through simple diffusion. how will they be transported? outside the cell inside the cell o a. the substances will move directly across the membrane from outside the cell to inside the cell. b. the substances will move through channels in the membrane proteins from outside the cell to inside the cell. o c. the substances will move through channels in the membrane proteins from inside the cell to outside the cell. o d. the substances will move directly across the membrane from inside the cell to outside the cell.
