Hi,

I don't know what exam board you're doing but if its OCR 21st Century,then B1- Genes, inheretence, cloning and stem cells (stuff along those lines).

B2- Keeping healthy...(sorry 4 sounding lyk some primary teacher)... that's basically disease, food, healthy eatings blah,blah,blah.

B3- Biodiversity and the theory of evolution...(isn't science so jam packed with funny theories?)...anyway if you're not doing OCR the I'm sorry for wasting your time and giving you the wrong information.....if your doing something else, then I could try and find out for you (I'm not doing OCR myself)

Hope I've helped and if I haven't someone else (in little more detail) is sure to turn up and rescue you.

Good luck suson
