About this deal
Practical experiments are an essential part of GCSE Biology. Tutors can guide students through the planning, execution, and interpretation stages of these experiments, honing their practical skills and scientific reasoning. 4. Exam Strategy and Practice Common Mistake: Students often confuse mitosis with meiosis, which is involved in sexual reproduction and results in four genetically different daughter cells. 2. Question: Explain how the structure of a villus aids absorption in the small intestine.
Answer: Osmosis is the movement of water molecules from an area of higher water concentration (or lower solute concentration) to an area of lower water concentration (or higher solute concentration), across a semi-permeable membrane.
Past GCSE biology papers are a valuable resource to familiarise yourself with the format and style of questions. 3. Revision Guides Answer: Antibiotic resistance can develop in bacteria due to genetic mutations that confer resistance. Bacteria with this resistance survive when exposed to the antibiotic, reproduce, and pass on the resistance to their offspring. Delving into the world of cells, organisms, and ecosystems, GCSE Biology opens up a fascinating avenue for understanding life and its intricate processes. This scientific subject is not only central to the GCSE but also forms the basis for future studies in medicine, environmental science, and several other prominent fields.

To give a rough equivalence, grades 7, 8, and 9 correspond to the old A and A* grades, with 9 being reserved for exceptional performance. Grades 4 to 6 represent a standard pass (previously grade C), and anything below 4 is considered a fail. A ‘strong pass’, defined by the Department for Education as a grade 5 or above, is often expected by many sixth forms and colleges for A-Level subject selection. Given the significant practical component in GCSE Biology, the ability to design experiments, make precise measurements, and handle equipment safely and effectively, is evaluated. 5.

This section examines how organisms maintain internal balance through homeostasis, including control of blood glucose levels and body temperature, and how organisms respond to their environments. Learn more about homeostasis and response. 6. Inheritance, Variation, and Evolution Explanation: Osmosis is a type of passive transport, meaning it doesn’t require energy. It happens naturally when there’s a difference in solute concentration across a semi-permeable membrane. Water molecules move to try and equalise the concentration on both sides of the membrane. Using flashcards (even virtual ones) are a great way to incorporate active recall into your GCSE Biology revision! 5. Put everything into practice using GCSE Biology past papers
