- Biochemistry
- Chemistry ABOUT living things
- Active Transport
- Movement of material through a cell membrane with the use of energy.
- Solution
- Mixture so evenly distributed that can't be taken apart. ( creamy italian dressing)
- Diffusion
- The movement of molecules from areas of greater concentration to areas of lesser concentration.
- Element
- All 1 kind of atom, some single (H,O,N), some diatomic (Na, Ag)
- Compound
- 2 or more elements joined together (water= 3 atoms=2 elements)
- Passive Transport
- Movement of material across a cell membrane without the use of energy.
- Atom
- Smallest unit of an element, wants to be neutral
- Suspension
- Mixture evenly distributed but then settles out (blood, italian dressing)
- Mixture
- Can be physically seperated, combination of substances. (salad)
- Organic Chemistry
