Study Notes
Laboratory Equipment
- An Erlenmeyer or Conical Flask is used in chemistry labs for mixing, heating, and measuring chemicals, and for preparing solutions.
- A Separatory Funnel is primarily used to separate two or more liquids of different densities.
- A Volumetric, Measuring or Graduated Flask is used to accurately measure and mix chemicals, and to prepare solutions of a specific volume or concentration.
- An Ordinary Funnel is used to pour liquids from one container to another without spilling, and is typically used when precision is not required.
Biology and Chemistry Basics
Organization of Living Organisms
- The fundamental level of organization that increases in complexity for body structure is: Cells → Tissues → Organs → Organ Systems → Organism.
Macromolecules
- Macromolecules are made up of monomers, which are smaller molecular units that combine to form large molecules.
Cells and Tissues
- The smallest independently functioning unit of a living organism is a cell.
- A group of many similar cells is called a tissue.
Elements
- Elements are made up of atoms, which are the building blocks of matter.
