- Harmful drugs are classified into Class A, B, and C
- Depressant and Stimulant drugs affect the nervous system by affecting transmission across synapses
- The mosquito is a vector that carries malaria
- Plasmodium is the pathogen that causes Malaria

- Immunisation protects against certain diseases by using harmless pathogens
- Changes in lifestyle can reduce the risk of some cancers
- It is a parasite and the human is the host
- Automatic systems in the body keep water, temperature and CO2 levels constant
- Vasodialation and vasoconstriction control body temperature
- The hormone insulin controls blood sugar levels, it converts excess blood sugar into glycogen
- Automatic systems in the body keep water, temperature and CO2 levels constant

- Automatic systems in the body keep water, temperature and CO2 levels constant
- Auxins are a group of plant hormones, they cause curvature by cell elongation
- These are involved in photo-tropism (response to light) and geotropism (response to gravity)

- Auxins are a group of plant hormones, they cause curvature by cell elongation
- The nervous system
- Light rays are refracted as they pass through the cornea and lens
- The eye accommodates by altering the shape of the lens
- Long/short sightedness is caused by the eyeball or lens being the wrong shape
- Monocular vision has a wider field of view, but poorer distance judgement than binocularvision
- Long/short sightedness is caused by the eyeball or lens being the wrong shape
- The eye accommodates by altering the shape of the lens
- Light rays are refracted as they pass through the cornea and lens
- A nerve impulse travels along the axon of a neutrone

- Long/short sightedness is caused by the eyeball or lens being the wrong shape
- The eye accommodates by altering the shape of the lens
- Light rays are refracted as they pass through the cornea and lens
- A neurotransmitter substances diffuse across a synapse, so the nerve impulse can pass to the next neurone
- A spinal refelx involves a receptor, sensory, relay, motor neurones and an effector
- The nervous system
- Variation and inheritance
- Alleles are different versions of the same gene
- Sex is determined by sex chromosomes, ** in female and xy in male
- Inherited disorders are caused by faulty alelles
- Most faulty alleles are recessive
- Human body cells have 23 pairs of chromosomes
- Dominant alleles are expressed if present; recessive are exposed if there is a lack of dominant
- Alleles are different versions of the same gene
