Question

now that you have a basic understanding of diffusion and osmosis, you can dig into an extremely important concept in the life sciences, concentration gradients. concentration gradients occur when dissolved substances, or solutes, differ in concentration in different areas—usually on either side of a cell membrane. they describe the direction that diffusion will occur, and biologists usually draw arrows to indicate their higher - to - lower directionality. suppose that the pink dots in this illustration represent the sugar glucose. which arrow correctly indicates the concentration gradient for glucose? heres another massively important concept in the life sciences: potential energy. potential energy is defined as the energy of position—analogous to the definition of kinetic energy as the energy of motion. energy, in turn, is the capacity to do something or to make something happen—to do work. here are some everyday examples of potential energy. a raised hammer has potential energy. when you swing it, the hammers potential energy is transformed to kinetic energy as it moves, and then to mechanical energy as it drives a nail. (if youve taken physics, you might remember that energy can be converted from one form to another, even though it cant be created or destroyed. its another one of those basic things about how the universe works.) the water molecules behind a dam have potential energy. when gates in the dam open, water molecules flow. did you fully understand the concept covered in this section? its muddy its clear submit answer

Explanation:

Diffusion occurs from an area of higher concentration to an area of lower concentration. In option C, there are more glucose (pink - dots) inside the cell and fewer outside, so the direction of the concentration gradient (and thus the direction of diffusion) is from inside the cell to outside the cell.

Answer:

C.
