hey, kim these are 4 AS(6BIO7) and the exam is over. I need A2 experiments which are:
1. Describe how to investigate the effects of temperature on the development of organisms( eg seedling growth rate, brine shrimp hatch rates)
2. Describe how to investigate rate of respiration practically.
3. Describe how to investigate the effects of excercise on tidal volume and breathing rate using data from spirometer traces.
4. Describe how to investigate habituation to a stimulus.
Thanks a lot.

well the thing is although i have 1 but it is only diagrams no notes at all so is hard to understand
for 2 and 3 u just need to know the spirometer and how it works
i m sorry to say i dont have much notes to provide there but ill check if i can find some notes on the spirometers in my txtbks then ill upload it for ya
sorry
