1. Diffusion rate investigation of glucose through Visking tubing, using Benedict’s test to estimate glucose concentration.
2. Variables in diffusion experiments, including solution volume, temperature, and Benedict's reaction consistency.
3. Graphical representation of diffusion rates in agar and calculation of diffusion rates at specified intervals.
4. Comparison of blood cells from different species using photomicrographs, focusing on structural and functional differences.
5. Calculation of actual cell dimensions using magnification and the preparation of comparative tables for blood cell types.
6. Plan diagrams of blood vessels in transverse sections and identification of structural adaptations for efficient transport.
