考官重點
官方報告整理常見失分位
- Miscalculating the size of cells due to incorrect unit conversions between millimeters and micrometers.
- Struggling to route mammalian reflex arcs correctly, often incorrectly including the conscious brain in the pathway.
- Failing to explain the role of constant environmental variables (like pH or temperature) in enzyme kinetics, focusing only on the active site.
常見誤解
- Assuming that white blood cells turn into antibodies, rather than producing them.
- Believing that Visking tubing allows starch molecules to move passively because starch is a sugar.
失分原因
- Incorrect scientific notation or failure to format standard form answers (e.g., leaving a large raw value instead of converting to standard form).
- Vague answers in Level of Response questions that lacked a logical sequence (such as missing the transitional stages of cell division or hormone release).
