Biology 9700 Practical Notes Guide

: Focus on 3–4 representative cells. Use clear, continuous lines and do not use shading or "fuzzy" sketching.

This usually involves titration, serial dilution, or enzyme kinetics.

Record all raw measurements to the same degree of precision. If your measuring cylinder has 1 cm3c m cubed graduations, record volumes to the nearest 0.5 cm3c m cubed (e.g., 10.0, 10.5, 11.0). biology 9700 practical notes

Tables are heavily penalized for minor omissions. Follow this structure every time:

You must be intimately familiar with the following biochemical tests and physiological setups. Biochemical Tests (Food Tests) : Focus on 3–4 representative cells

The independent variable goes on the x-axis. Use at least half the provided grid. Points should be joined with ruled straight lines unless a curve is specifically requested. Error Analysis: Distinguish between systematic errors (instrumental) and random errors

You will frequently be asked to dilute a stock solution (e.g., 1.0% glucose) to create a range of concentrations. Record all raw measurements to the same degree of precision

Maintain accurate proportions of the tissues (e.g., the cortex should not look thicker than it is relative to the vascular bundles).
