I have some few questions from unit 4 (A-level):
- Suggest two enviromental conditions that could increase the rate of oxygen production in plants
- Describe how a forest could be managed sustainably in order to ensure a continual supply of timber for the future
-Name a method by which global sea temperatures can be monitored
-Some recovery in the great barrier reef may be taking place at present. Suggest a possible explanation for this, other than change in sea temperature
-HIV positive people were excluded from the data (ie data about number of new TB cases). If they have been included suggest how the data would differ. Give an explanation to your answer.
-Give one example of physical evidence that could be retained from the original investigation of a crime scene and explain why the sample is suitable for a DNA test to be carried out.
