  1. 1Phospholipids in a plasma membrane are arranged in a [blank_start]bilayer[blank_end] and have [blank_start]hydrophilic[blank_end] phosphate heads and [blank_start]hydrophobic[blank_end] lipid tails.
    1. Abilayer
    2. Bhydrophilic
    3. Chydrophobic
  2. 2Risk factors associated with coronary heart disease
    1. ASmoking
    2. BGender
    3. CDoing exercise
    4. DBeing average weight
    5. ELow salt intake
  3. 3During a heart attack areas of heart muscle are deprived of [blank_start]oxygen[blank_end] because of a reduced blood flow in the [blank_start]coronary arteries[blank_end] so they cannot carry out [blank_start]aerobic[blank_end] respiration.
    1. Aoxygen
    2. Bcoronary arteries
    3. Caerobic
  4. 4How bacteria are destroyed by phagocytes:
    Phagocytes form a [blank_start]phagosome[blank_end] around the bacteria. Lysosome empties its contents into the [blank_start]phagosome[blank_end] where [blank_start]lysozyme[blank_end] is released with [blank_start]hydrolyses[blank_end] teh bacteria.
    1. Aphagosome
    2. Bphagosome
    3. Clysozyme
    4. Dhydrolyses
  5. 5An inhibitor of amylase is added to some food. How could this lower the blood glucose concentration?
    Fewer [blank_start]enzyme-substrate[blank_end] complexes are formed therefore less starch is digested to [blank_start]maltose[blank_end] meaning less glucose is formed which will lead to a reduced absorption of [blank_start]glucose[blank_end].
    1. Aenzyme-substrate
    2. Bmaltose
    3. Cglucose
  6. 6Fibrosis can cause changes to FEV since [blank_start]scar[blank_end] tissue has developed. [blank_start]Scar[blank_end] tissue cannot [blank_start]recoil[blank_end] which will mean that inhalation is [blank_start]restricted[blank_end].
    1. Ascar
    2. BScar
    3. Crecoil
    4. Drestricted
  7. 7Whole cell vaccines could cause harmful side effects since some bacteria may still be [blank_start]alive[blank_end] so the bacteria could [blank_start]reproduce[blank_end]. Also the [blank_start]toxins[blank_end] may not be affected by the heat which was used in the process of attenuating the virus.
    1. Aalive
    2. Breproduce
    3. Ctoxins
  8. 8Competitive inhibitors have a [blank_start]similar[blank_end] shape to the enzyme's substrate so can bind to the [blank_start]active site[blank_end]. They [blank_start]can[blank_end] be overcome by adding more substrate. Non-competitive inhibitors bind to a [blank_start]second active site[blank_end] which will [blank_start]alter[blank_end] the shape of the active site of the enzyme. These [blank_start]cannot[blank_end] be overcome by adding more substrate.
    1. Asimilar
    2. Bactive site
    3. Ccan
    4. Dsecond active site
    5. Ealter
    6. Fcannot
  9. 9A hierarchy contains groups within [blank_start]groups[blank_end] with [blank_start]no[blank_end] overlap between groups.
    1. Agroups
    2. Bno
  10. 10Independent segregation in meiosis produces [blank_start]haploid[blank_end] cells and will arrange the homologous pairs [blank_start]randomly[blank_end].
    1. Ahaploid
    2. Brandomly
