First off, Is this all this is in B1:

Classification, Variation, Natural Selection, Speciation, Genes, Genetic Diagrams, Genetic Disorders,

Heomeostatsis, Nervous System, Stimuli Reflexes etc, Insulin Diabetes, Hormones, Plants Growth Hormones

Drugs, Smoking, Alcohol, Antiseptics, Pathogens, parasitism & mutualism, Recycling, Indicator Species, Carbon + Nitrogen Cycles, Enviroment, Biomass.

So, I have 2 more questions:

1) What are the symtoms and other details on CF and Sickle Cell Anemia. It's almost always there and always a 3 marker at least, but I can never find what they are.

2) Does the Nervous System & Biomass ever come up? Same with Reflexes and Stimuli? Spent ages revising it but haven't seen it in any of the past papers.

Thanks for any help.
