1.
A researcher who expects a drug to work judges 'improvement' by looking at patients. What problem is most likely?
Bias, because judgement rather than measurement is used
Too large a sample
The independent variable is measured
Peer review is impossible
2.
Which of the following statements can be made from review of these data? (see the figure)
Which of the following statements can be made from review of these data? (see the figure)
Enzyme 1 works best in a basic environment and at a lower temperature.
All three enzymes work best above 20 C when pH is held at 7.
Enzyme 1 is more efficient than enzyme 2 at 10 C and pH 7.
The pH does not affect the efficiency of enzyme 3.
All three enzymes work better in an acidic environment than a basic one.

The word equation for aerobic respiration is:
Glucose → lactic acid
Glucose → ethanol + CO₂
Glucose + oxygen → carbon dioxide + water
Carbon dioxide + water → glucose + oxygen

You cross-pollinate only the darkest pink pea flowers. In the new generation, what would you expect to see?
You cross-pollinate only the darkest pink pea flowers. In the new generation, what would you expect to see?
The relative numbers of flower colours would remain unchanged.
You would see disruptive selection.
Your results would show directional selection.
The relative numbers of white flowers would increase.

A dialysis bag containing 0.5 M solution is placed in a beaker of 0.6 M solution. After a while, what would you expect to have happened?
A dialysis bag containing 0.5 M solution is placed in a beaker of 0.6 M solution. After a while, what would you expect to have happened?
Net flow of water out of the bag, so it decreases in size.
Net flow of water into the bag, so it swells in size.
The bag stays exactly the same size because no water moves.
The solute moves out of the dialysis bag into the beaker.
