OCR GCSE 21st Century Biology
Biology, like Chemistry and Physics, consists of three units from the Science , Additional Science and Further Additional Science courses, along with a controlled assessment. All three written papers have to be taken at the same time at the end of the course.
B1: You and your genes
~ What are genes and how do they affect the way that organisms develop?
~ Why can people look like their parents, brothers and sisters, but not be identical to them?
~ How can and should genetic information be used?
~ How can we use our knowledge of genes to prevent disease?
~ How is a clone made?
B2: Keeping healthy Module
• How do our bodies resist infection?
• What are vaccines and antibiotics and how do they work?
• What factors increase the risk of heart disease?
• How do our bodies keep a healthy water balance?
B3: Life on Earth
~ Systems in balance – how do different species depend on each other?
~ How has life on Earth evolved?
~ What is the importance of biodiversity?
B4 – The processes of Life
~ How do chemical reactions take place in living things?
~ How do plants make food?
~ How do living organisms obtain energy?
B5 – Growth and development
~ How do organisms develop?
~ How does an organism produce new cells?
~ How do genes control growth and development within the cell?
B6 – Brain and mind
~ How do animals respond to changes in their environment?
~ How is information passed through the nervous system?
~ can reflex responses be learned?
~ How do humans develop more complex behaviours?
B7 – Using biology
~ Control systems
