Study Notes
Life Science Midterm Study Guide - Unit 1
- Scientific Rules: Scientific laws describe patterns in nature
- Scientific Theories: Scientific theories explain observations of events based on knowledge from observations and investigations
- Hypothesis: A testable prediction or statement
- Control Group: Used in controlled experiments to observe the independent variable, where the independent variable does not change
- Experimental Group: This is the part of a controlled experiment that is measured and changed to observe results
Life Science Midterm Study Guide - Unit 2
- Compound Light Microscope Magnification: To find the total magnification of a compound light microscope, multiply the ocular lens magnification by the objective lens magnification
- Cell Discovery: Robert Hooke was the first person credited with discovering cells
- Cell Theory: All living things are made up of one or more cells
- Prokaryotic vs. Eukaryotic Cells: Eukaryotic cells have their genetic material surrounded by a membrane, while prokaryotic cells do not
- Animal Cells: Animal cells do not have cell walls
