- Diet and Exersize
- Blood pressure has 2
readings: diastolic and
systolic, in mmHg
- Smoking, a high alcohol intake
and a diet rich in saturated fats
and salt increase blood
pressure
- High blood pressure can
damage the brain (stroke)
and kidneys
- High blood pressure can
damage the brain (stroke)
and kidneys
- Smoking, a high alcohol intake
and a diet rich in saturated fats
and salt increase blood
pressure
- Being fit is the ability to do
exersize, being healthy is
being free from disease
- A balanced diet will vary
according to age, gender,
activity, religion or personal
choice
- Blood pressure has 2
readings: diastolic and
systolic, in mmHg
- Drugs and Disease
- Harmful drugs are
classified as class A, B
and C. Class A being the most harmful
- Depressant and stimulant drugs
affect the nervous system by
affecting the transmission across
synapses
- High levels of
alcohol can cause
cirrhosis of the
liver
- High levels of

- Immunisation protects against
certain diseases by using
harmless pathogens
- Changes in the lifestyle can
reduce the risk of certain
cancers
- The mosquito is the vector that carries malaria
- Plasmodium is the pathogen
that causes malaria. It is a
parasite and humans are its
host
- Plasmodium is the pathogen

and C. Class A being the most harmful
- Homeostatis and
Plant Hormones
- Homeostatis is maintaining a
constant internal environment
- Vasodilation and vasconstriction
control heat transfer from the body
- Auxins are involved in phototropism
(response to light) and geotropism
(response to gravity)
- A spinal reflex involves a receptor, sensory, relay and motor neurones and an
effector
- A spinal reflex involves a receptor, sensory, relay and motor neurones and an
effector
- Auxins are involved in phototropism
(response to light) and geotropism
(response to gravity)
- Auxins are a group of plant
hormones. They cause shoot
curvature by cell elongation
- The hormone insulin controls blood sugar levels. It
converts excess blood glucose into glycogen
- Automatic systems in the body keep water,
temperature and carbon dioxide levels
constant
- Automatic systems in the body keep water,
temperature and carbon dioxide levels
constant
- The hormone insulin controls blood sugar levels. It
converts excess blood glucose into glycogen
- Homeostatis is maintaining a
constant internal environment
- The Nervous System
- Light rays are refracted as they pass through the
corneas and lens
- Monocular vision has a wider field of
view but poorer distance judgement than
binocular vision
- Long and short sight is caused by the
eyeball or lens being the wrong shape
- The eye accommodates by altering the shape of the lens
- Long and short sight is caused by the
eyeball or lens being the wrong shape
- A nerve impulse travels along the axon of a neurone
- A neurotransmitter substance diffuses across a synapse, so
the nerve impulse can pass to the next neurone
- A spinal reflex involves a receptor,
relay, sensory and motor neurone and
an effector
- A spinal reflex involves a receptor,
relay, sensory and motor neurone and
an effector
- A neurotransmitter substance diffuses across a synapse, so
the nerve impulse can pass to the next neurone
- Light rays are refracted as they pass through the
corneas and lens
- Variation and Inheritance
- Inherited disorders are cause by faulty alleles
- Most faulty alleles are recessive
- Most faulty alleles are recessive
- Dominant alleles are expressed if present, recessive alleles are
expressed in the absence of a dominant allele
- Alleles are different versions of the same gene
- Alleles are different versions of the same gene
- Being homozygous is having 2 identical alleles, being heterozygous
is having two different alleles
- Human body cells have 23 pairs of chromasomes
- Sex is determined by sex chromosomes, XX in female, XY in male
- Sex is determined by sex chromosomes, XX in female, XY in male
- Inherited disorders are cause by faulty alleles
