Homo Sapiens Brain diagram
Specification Link
This nervous system diagram is used for: Explain the effects of alcohol on the liver and brain function.
What To Explain
Alcohol can affect brain function by slowing nervous-system responses and impairing coordination or decision making.
Exam Answer Move
The mapped objective is: Explain the effects of alcohol on the liver and brain function. A strong answer links the brain to nervous-system control and the effect of alcohol on function.
Enzyme Blue 3d diagram
Recognising Enzyme Blue 3d
Enzyme Blue 3d supports The human digestive system by giving students a diagram they can connect to the specification point being tested.
What To Explain
Enzymes have specific active sites and catalyse reactions by helping substrates form products.
Syllabus Link
