The rate at which reactions occur in cells.
Making cell membranes
Ignaz Semmelweis
Hand washing in hospitals
The antigens on pathogens
Antibiotics have no effect on a virus
An injection of a weakened or dead pathogen
2) Coordination and control

6.
7.
Bright light, sound, touch, temperature change...
Receptor -> Sensory Neurone -> CNS -> Motor
Neurone -> Effector
Makes an egg mature in the ovary
Thickens the lining of the uterus
Hair stand on end and muscles “shiver”
Lowers blood glucose level
Secreted at shoot tip, area in light is destroyed to
dark side grows, bending shoot towards light.
3) Drugs
1.
2.
3.
4.
5.
6.
Neither patient nor doctor know if they have drug
or placebo.
Drug that lowers cholesterol
Not tested on pregnant women, caused limb
abnormalities in babies.
Addicted to nicotine.
Not scientifically proven
Unfair advantage over others especially those
who couldn’t afford them
4) Adaptation
1.
2.
3.
4.
5.
6.
Stops cold water getting to skin.
Can judge distance to prey.
Surface area to volume ration
Stop animals eating them, especially after water.
Fruits, flying seeds, sticky seed pods etc...
Populations of animals, lichen coverage, average
temperatures, pollution levels in rivers etc...
5) Energy in biomass
1.
2.
3.
4.
5.
Total mass rather than number of organisms
Movement, inefficient digestion, repair of
injuries, not being eaten by predator...
Worms and maggots, accelerate decomposition
and release trapped carbon
Photosynthesis and dissolving in oceans.
Worms/maggots -> bacteria/fungi which break
down complicated carbon containing molecules
in carbon dioxide.
6) Variation
1.
2.
3.
4.
5.
6.
A sex cell
Only one parent in asexual
Mixture of two parent’s chromosomes
Reproduce a perfect or ideal specimen
Electric shock
They may breed with near by normal species and
create a mutation. They may also take over
existing species and wipe it out leaving only the
modified one.
7) Evolution
1.
2.
3.
4.
5.
Lamark thought you could change your own
characteristics over time, Darwin thought that new
characteristics simply made you more likely to survive
and have more offspring.
Did not know about chromosomes/genetics then.
Evolution is made up of many individual stages of
natural selection.
Most successful individuals hunt/eat better or fight
better so will live longer and have more offspring.
Beaks adapted for the food they ate
How did you do out of 42?
