Biology 9700 Practical - Notes

That word haunted her.

When investigating factors like enzyme concentration, substrate concentration, temperature, or pH:

are standardized samples where the effect of the independent variable is removed. biology 9700 practical notes

Used to create a linear concentration gradient (e.g., 1%, 2%, 3%, 4%, 5%). Formula: is concentration and is volume). Example: To make of a 2% glucose solution from a 10% stock:

Include both the variable name and its metric unit, separated by a forward slash (e.g., Time / s or Concentration / % ). Never put units inside the data cells. That word haunted her

from Tube 2 and transfer to Tube 3. Mix thoroughly. (Tube 3 is now 2.5%).

The exam often tests your ability to handle specific biological investigations: Microscopy eyepiece graticule stage micrometer for accurate measurements. Biological Molecules Formula: is concentration and is volume)

Common biochemical tests assessed in practical contexts include:

Judging endpoint colors by eye is subjective. Fix: Use a colorimeter or compare against a standardized color chart.

Add iodine in potassium iodide solution. A blue-black color indicates starch. Enzyme Kinetics Experiments usually involve catalase, amylase, or protease.
