Edexcel BIOLOGY Doubts!!!!

--- Quote from: AbdulKareem on January 21, 2011, 04:14:37 pm ---Here's what I think are some correct answers;
-Any condition which will increase the rate of photosynthesis over respiration so the plant produces more oxygen (e.g. 1.higher temperature 2.brighter sunlight/light... etc.)
-By planting seeds after cutting trees.
-Maybe reducing CO2 emissions? Hmm it's unlikely.. I'm not sure to be honest.
-The increasing acidity of the sea (lower pH because of more CO2 absorption by the sea).
-The number of people affected with TB would have been higher. Explanation: TB is an opportunistic disease which only attacks when your immunity is at its weakest. HIV kills the T-helper cells in your immune system which makes it very weak, and so TB finds the perfect time to attack.
-Blood/Falling hair... etc.
Refer to DNA profiling. I'm sorry but I'm a bit short on time right now.
I hope it helps :D
Good luck mate!

Perhaps reading what you post before you post it is a good idea ;D
