• The most enjoyable, amazing, challenging,
  exciting, interesting, applicable, fascinating,
  and fun class you will ever take!!!!!

2
GENERAL BIOLOGY

• Core themes in Biology
• subdisciplines
• common concepts that underlie all biological study

3
WHAT IS LIFE?

• If something is considered to be living, what
  characteristics does it possess?

4
Lifes Levels of Organization

• Ecosystem
• Community
• Population
• Organism
• Organ system
• Organ
• Tissue
• Cell
• Molecule Atom

5
Hierarchical levels

• Determine the level Larger than Life!!!

6
Hierarchical levels

• Determine the level
• The microcosmic world

7

  Rose and Uncle Fritz.

10
Hierarchical levels

• Determine the level I feel as frozen as
  an icecube when its winter.

11
The Scientific Method

• ?Reasons for the scientific method
• ? 5-step process
• 1. Observations
• 2. Questions
• 3. Hypotheses
• must be testable
• 4. Predictions
• 5. Tests

12
Testing the Hypothesis

• variables
• independent vs. dependent
• effect on test results
• test group vs. control group
• difference
• size
• positive control/negative control
• repeatability of tests
• reliability or results

13
Once a hypothesis is tested, then what??????

• Conclusion/re-access the original hypothesis
• Retest over and over again
• THEN......
• theory
• ITS THE LAW!!!!!!!!

14
The Scientific Method

• An investigator spills dye on a culture plate and
  then notices that the bacteria live despite
  exposure to sunlight. He decides to expose 2
  culture plates to ultraviolet light--one plate
  contains bacteria and dye the other plate
  contains only bacteria. The bacteria on both
  plates die.

Lifes Diversity

• Classification of lifes diversity in an attempt
  to better understand.
• 5 Kingdoms
• 1. Animalia 2. Plantae
• 3. Protista 4. Monera
• 5. Fungi

17
Interconnecting Webs

• Organisms dont exist in isolation from the
  environment.
• Producers, Consumers, Decomposers
• Photosynthesizers
• carbon dioxide water sunlight
• --gt food
• ALL organisms depend on producers for food

18
Kingdoms

• How are you more like a microscopic amoeba, than
  an amoeba is like a bacterium?
