常见错误

1. 1high涉及分数: 1Cell respiration

   Writing that glucose 'produces' energy during cell respiration.

   如何避免: Describe respiration as the chemical oxidation of glucose to yield ATP (or chemical energy stored in ATP).
2. 2high涉及分数: 2Ecology

   Writing separate, sequential paragraphs of descriptions when a question asks to 'compare and contrast' datasets or biological features.

   如何避免: Use explicit comparative terms side-by-side (such as 'whereas', 'both', 'higher than', 'lower than') to construct direct comparisons.
3. 3high涉及分数: 1Cell structure

   Losing calculation marks for cell size or magnification due to incorrect unit conversions (such as dividing millimeters on paper directly by micrometers).

   如何避免: Always convert all measurements to the same unit (ideally micrometers, \(\mu\text{m}\), where 1 mm = 1000 \(\mu\text{m}\)) before dividing.
4. 4medium涉及分数: 2Defence against disease

   Believing that antibiotics can kill or target viruses.

   如何避免: Explain that viruses lack their own metabolic pathways, cell walls, or 70S ribosomes, which are the targets of antibiotic action.
5. 5high涉及分数: 1Cell respiration

   Using the vague term 'amount' or 'quantity' when identifying independent or dependent variables in experimental descriptions.

   如何避免: Use exact scientific terms such as 'mass', 'volume', or 'concentration', and always state the associated units.
6. 6medium涉及分数: 2Water

   Drawing a water molecule diagram without the V-shape or omitting partial dipoles.

   如何避免: Draw the water molecule with a clear V-shape angle, label \(\delta^-\). on the oxygen atom, \(\delta^+\) on both hydrogen atoms, and draw dashed lines between oxygen and hydrogen of adjacent molecules for hydrogen bonds.
