please I need these experiment for edexcel A2 Biology
1. Describe how to carry out a study on the ecology of a habitat to produce valid and reliable data(including the use of quadrats and transects to assess abundance and distribution of organisms and the measurement of abiotic factors, eg solar energy input, climate, topography, oxygen avaliability and edaphic factors.
2. Describe how to investigate the effects of temperature on the development of organisms( eg seedling growth rate, brine shrimp hatch rates)
3. Describe how DNA can be amplified using the polymerase chain reaction(PCR).
4. Describe how gel electrophoresis can be used to separate DNA fragments of different length.
5. Describe how to investigate the effect of different antibiotics on bacteria.
6. Describe how to investigate rate of respiration practically.
7. Describe how to investigate the effects of excercise on tidal volume and breathing rate using data from spirometer traces.
8. Describe how to investigate habituation to a stimulus.
Thanks a lot.
