The surface area/volume ratio is an important factor for one-celled organisms. as a cell's volume grows, its surface area/volume ratio making it to acquire enough nutrients via diffusion. a) increases; harder b) decreases; more difficult c) decreases; less difficult d) increases; use active transport

Most scientific questions are based on opinions. hypotheses. observations. experimental data.

What happens as electrons move along the chain of molecules known as the electron transport chain? they gain energy, which causes atp molecules to lose phosphate groups. they gain energy, which causes h *ions to join with oxygen to produce water. they lose energy, which is then used by the cell to make atp. they lose energy, which is then used to break down atp.

What is the function of the root cap? a. extra-absorbent cells in the root cap absorb more water and nutrients b. protect the meristematic area of the stem c. contains sensors for sunlight d. increases surface area of the root
