1. Which of the following functions is performed by the blood?
Makes body hair grow faster
Transfers gases and other substances
Prevents sun burn
Prevents bee stings
2. One of the factors below will not disturb the “balance” of a chemical reaction:
temperature
the presence of phosphorus
concentration
pressure
3. The concentration of gases is expressed as:
Picograms
Kilograms
Partial concentration
Partial pressure
4. When carbon dioxide tension is high, the haemoglobin will:
show no change
not attract any oxygen molecules
load oxygen slowly
load oxygen faster
5. Le Chatelier’s Principle relates to:
a factor that affects blood groups
factors that affect the dissociation of white blood cells
factors that affect the balance between red and white blood cells
factors that affect the oxygen dissociation curve of haemoglobin
6. The pigment found in red blood cells is called:
diploid
haemoglobin
haemophilia
haploid
