Sections:
- Observations – Grouping and Comparing Materials:
- Identify parts in a Rhizopus micrograph and label key structures in microorganism diagrams, noting features like eukaryotic status and bacterial shape.
- Observations – Drawing:
- Draw and label a basic bacterium structure.
- Data Interpretation – Bacterial Growth:
- Analyze bacterial growth through binary fission, identifying variables and plotting bacterial numbers over time.
- Data Interpretation – Antibiotic Sensitivity:
- Interpret an experiment on antibiotics’ effects on bacteria in a petri dish, determining resistance and sensitivity based on growth inhibition zones.
