- e A solution in which the concentration of solutes is essentially equal to that of the cell which resides in the solution. examples interstitial fluid and intravenous solutions
5 Multiple choice questions
- Division of the cytoplasm during cell division after the cell nucleus has divided.
- Movement of molecules from an area of higher concentration to an area of lower concentration.
- A process that separates materials through a membrane based on the size of their particles.
- a gradient in concentration of a solute that molecules move down and the greater the difference in concentration between the two areas, the faster diffusion occurs. It is An increase or decrease in the density of a chemical substance in an area., A difference in concentration between two areas.
- Communicating Junctions; channels that allow small molecules to flow through protein-lined pores between cells. common in the heart and embryonic cells.

protein synthesis → Division of the cytoplasm during cell division after the cell nucleus has divided.
mitosis → Diffusion of water through a selectively permeable membrane
active transport → Energy-requiring process that moves material across a cell membrane against a concentration difference or gradient
osmosis → Diffusion of water through a selectively permeable membrane
deoxyribonucleic acid → nucleic acid found in all living cells: carries the organism's hereditary information.
