2. involves the breaking of many of the weak linkages, or bonds
3. Any of the tiny blood vessels that connect the smallest arteries to the smallest veins
8. passive movement of particles (atoms, ions or molecules) from a region in which they are in higher concentration to regions of lower concentration.
9. a cartilaginous tube that connects the pharynx and larynx to the lungs, allowing the passage of air, and so is present in almost all air-breathing animals with lungs.
10. A membrane that is permeable to the small molecules of water and certain solutes but does not allow the passage of large solute molecules
12. The specific region of an enzyme where a substrate binds and catalysis takes place or where a chemical reaction occurs.
13. the movement of water or another solvent through a plasma membrane from a region of low solute concentration to a region of high solute concentration
14. tiny sacs within our lungs that allow oxygen and carbon dioxide to move between the lungs and bloodstream

1. the process of particles, moving through a solution or gas from an area with a higher number of particles to an area with a lower number of particles
4. movement of ions or molecules across a cell membrane into a region of higher concentration, assisted by enzymes and requiring energy.
5. the gills of an animal, most typically an amphibian, that are exposed to the environment
6. A minute blind-ended lymph vessel that occurs in each villus of the small intestine.
7. When an object/cell is very small, it has a large surface area to volume ratio, while a large object/ cell has a small surface area to volume ratio.
11. Proteins are made from these long chains
