Study Notes
Colloidal Systems
- A colloid is best described by illustrations I and III.
- The unique behaviors and properties exhibited by particles that arise from the interactions between the dispersed particles and the surrounding medium is known as the colloidal effect.
Atomic Structure
- An atom consists of neutrons, electrons, and protons.
- Protons and neutrons are located in the nucleus (labelled IV in Diagram X).
- Electrons are not located in the nucleus.
Cellular Classification
- Diagram W shows organisms that need to be classified as prokaryotes or eukaryotes.
