Does anyone have resources/websites for the all the practicals for AS level Biology. I'm worried as I don't know much about the practicals and will panic if they come up in the exam. Below is the list of all the practicals.
Practical 1 - Investigate the effect of caffeine on the heart rate in daphnia.
Practical 2 - Investigate the vitamin C content of food and drink.
Practical 3 - Investigate membrane structure, including the effect of alcohol concentration or temperature on membrane permeability.
Practical 4 - Investigate the effect of enzyme and substrate concentrations on the initial rates of reactions.
Practical 5 - Prepare and stain a root tip squash to observe the stages of mitosis.
Practical 6 - Identify sclerenchyma fibres, phloem sieve tubes and xylem vessels and their location within stems through a light microscope.
Practical 7 - Investigate plant mineral deficiencies.
Practical 8 - Determine the tensile strength of plant fibres.
Practical 9 - Investigate the antimicrobial properties of plants, including aseptic techniques for the safe handling of bacteria.
