B1
The organelle which controls activities of the cell and contains DNA.
Nucleus.
The tissue that contracts to move bones.
Muscle.
The type of microorganism that causes the flu.
Virus.
Carbon Dioxide.
The type of neurone carrying impulses from receptors to the CNS.
The organelle in the cell where aerobic respiration happens.
Mitochondria.
The enzyme that breaks down starch.
Amylase.
How pathogens can be spread (3 ways).
Airborne/Water/Close Contact.
The word equation for photosynthesis.
Carbon dioxide + Water --> Glucose + Oxygen
The function of the relay neurone.
Connects sensory and motor neurones in the CNS.
A structure found in plant cells but not animal cells.
Either: Chloroplast, Vacuole, Cell wall.
The organ where bile is produced.
Liver.
What white blood cells produce to destroy specific pathogens.
Antibodies.
A factor that can limit rate of photosynthesis.
Light intensity, Concentration of carbon dioxide and Temperature.
What a synapse is.
A gap between 2 neurones.
Mitosis.
How the structure of a red blood cell helps its function.
Large surface area / no nucleus = carries more oxygen.
The reason why you can catch a cold more than once.
Viruses mutate/change very quickly.
Plants store glucose as starch, what characteristic of glucose allows this to happen?
Insoluble.
The reason why reflexes are faster than voluntary responses.
They bypass the brain.
Why stem cells are useful in medicine?
Can differentiate into other types of cell.
It pumps blood at a higher pressure as it is pushed all around the body.
How vaccination protects the body from future infection.
Stimulates antibody production, this information is stored by the memory cells in case of future infection.
How the body reacts during exercise.
Increased heart rate, Increased breathing rate, More gas exchange.
The process of a reflex.
Stimulus, Receptor, Sensory, Relay, Motor, Effector, Response.
