To succeed in the Biology 9700 practical component, students should: | Time / s | Temperature / °C

You must master both proportional and logarithmic dilutions. This is critical for determining the effect of substrate/enzyme concentration or finding the water potential of plant tissues. Enzyme Studies: This is critical for determining the effect of

Master Your AS Level Biology (9700) Practical Exam The AS Biology Paper 3 (Advanced Practical Skills) is often the most nerve-wracking part of the 9700 syllabus. Unlike theory papers, it demands a blend of manual dexterity, sharp observation, and precise data management within a strict 2-hour window.

Good luck, biologists. Remember: Measure twice, cut once, and always zero your balance.

Things you must keep constant (e.g., temperature using a water bath, volume of reagents). Use the word "volume" or "concentration" specifically—never just say "amount." 4. Precision and Data Presentation
