Differentiate between DNA and RNA. (2)
- DNA = deoxyribonucleic acid; genetic information or blueprint of an organism
- RNA = ribonucleic acid; carries information or commands
Differentiate between osmosis, passive transport, and active transport. (3)
- Osmosis = passive diffusion of water through a membrane
- Passive transport = movement of substances through a membrane WITHOUT cellular energy
