Can someone give me a general understanding of these chapters and the definitions . Im just lost D:
We're in the same boat ! :(
But you can chose between doing genetics or ecology, so stick to the ecology question if thats easier for you to study?
excretion comes up every year so learn that well
genetic engineering is easy, just learn the stages and have a few lines on each plus an example of a plant, animal and micro-organism being genetically modified.. an easy way to remember the stages is I Caught Leprosy Through Careless Experimentation.
Hope that helped a little :) x
