Across 1. the tendency toward a relatively stable equilibrium between interdependent elements, especially as maintained by physiological processes. 6. the modification or control of a process or system by its results or effects, e.g., in a biochemical pathway or behavioral response. 9. the process by which different kinds of living organisms are thought to have developed and diversified from earlier forms during the history of the earth. 11. any of the class of sugars (e.g., glucose) that cannot be hydrolyzed to give a simpler sugar. 12. having a lower osmotic pressure than a particular fluid, typically a body fluid or intracellular fluid. 13. denoting or relating to a solution having the same osmotic pressure as some other solution, especially one in a cell or a body fluid. 14. a process by which molecules of a solvent tend to pass through a semipermeable membrane from a less concentrated solution into a more concentrated one, thus equalizing the concentrations on each side of the membrane. 15. spontaneous passive transport of molecules or ions across a cell's membrane via specific transmembrane integral proteins.

Down 2. the production of new living organisms by combining genetic information from two individuals of different types (sexes). In most higher organisms, one sex (male) produces a small motile gamete that travels to fuse with a larger stationary gamete produced by the other (female). 3. reproduction by which offspring arise from a single organism, and inherit the genes of that parent only 4. a region of tissue, or a molecule in a cell membrane, that responds specifically to a particular neurotransmitter, hormone, antigen, or other substance. 5. the chemical processes that occur within a living organism in order to maintain life. 7. the action of spreading the light from a light source evenly so as to reduce glare and harsh shadows. 8. a substance that has a molecular structure consisting chiefly or entirely of a large number of similar units bonded together, e.g., many synthetic organic materials used as plastics and resins. 10. having a higher osmotic pressure than a particular fluid, typically a body fluid or intracellular fluid.
