Biology

== Biology- the study of life==

Biology is the study of life. In biology at GCSE different information is split up into different modules (B1, B2,B3). The 3 main topics for GCSE are:

Human biology. (this covers Enzymes, hormones, healthy lifestyle, drugs, the body and Pathogens)

Plants and horticulture ( this covers Osmosis, plant hormones and Genetic modification.)

Animals and the Environment. (this covers Evolution, Variation, cloning, Genes, chromosomes and DNA, fossil fuels and Extinction)
