Edexcel | GCSE Separate Science Biology | Higher | Paper 1 | 2025 Predicted Topics & Revision Guide
Here are our 2025 predictions for Edexcel GCSE Biology Higher Paper 1! 🔬✨ We’ve carefully analysed trends, but remember—revise everything to be fully prepared! 💡📚
🦠 Cell Structure & Specialised Cells
✅ Prokaryotic vs. Eukaryotic cells – key differences (nucleus, organelles)
✅ Specialised cells & adaptations:
-
Sperm cell – tail for swimming, mitochondria for energy
-
Nerve cell – long with branches to send signals quickly
-
✅ Functions of cell organelles – nucleus, mitochondria, ribosomes, etc.
⚡ Enzymes
✅ Lock and key theory – enzyme fits perfectly with its substrate
✅ Factors affecting enzyme activity:
-
Temperature & pH – too high or too low can denature enzymes
-
Substrate concentration – increases rate until saturation point
✅ Digestive enzymes: -
Amylase → starch → glucose
-
Protease → protein → amino acids
-
Lipase → fats → fatty acids + glycerol
🧠 The Brain & Imaging
✅ Key parts of the brain & functions:
-
Cerebrum – thinking, memory, emotions
-
Cerebellum – balance and coordination
-
Medulla – heartbeat and breathing
✅ Brain imaging techniques: -
MRI scans – detect brain damage & diseases
-
CT scans – 3D images of the brain structure
🔬 Microscopy
✅ Light vs. Electron microscopes – resolution, magnification, and what they show
✅ How to calculate magnification:
Magnification = Image size ÷ Actual size
✅ How to prepare a slide – staining cells to see structures clearly
🧬 Inheritance, Sex Determination & Sex-Linkage
✅ Chromosomes:
-
XX = female
-
XY = male (Y chromosome determines male characteristics)
✅ Sex-linked conditions – some genes (e.g. for colour blindness & haemophilia) are carried on the X chromosome
✅ How to use Punnett squares to predict inheritance
🐶 Selective Breeding
✅ Humans choose parents with desirable traits
✅ Used for:
-
Farming – high-yield crops, disease-resistant livestock
-
Pets – dogs with gentle temperaments
✅ Risks – inbreeding causes health problems & reduces genetic variation
🧬 Cloning
✅ Types of cloning:
-
Tissue culture – growing plants from a few cells
-
Embryo transplants – splitting an embryo to produce clones
-
Adult cell cloning – nucleus transfer (e.g. Dolly the sheep)
✅ Advantages & risks: -
Good for conservation & medicine
-
Reduces genetic diversity
🌱 Sexual & Asexual Reproduction
✅ Sexual reproduction – genetic variation, slower process
✅ Asexual reproduction – identical offspring, fast process
✅ Examples:
-
Bacteria & fungi reproduce asexually
-
Plants can do both! (e.g. strawberries use runners)
🦠 Aseptic Technique Practical
✅ Why it’s important: Prevents contamination from bacteria
✅ Steps:
-
Sterilise equipment (flaming inoculating loop)
-
Seal Petri dish (to prevent unwanted bacteria growth)
-
Incubate at 25°C (prevents harmful bacterial growth)
💊 Drug Trials
✅ Stages of drug testing:
-
Preclinical trials – tested on cells & animals
-
Clinical trials (Phase 1-3) – tested on humans
-
Double-blind trials – patients don’t know if they have the real drug or a placebo
✅ Why blind trials are important? – Removes bias and increases reliability
🦠 Monoclonal Antibodies
✅ How they are made:
-
Fuse a B-lymphocyte (white blood cell) with a tumour cell
-
Creates a hybridoma cell that produces monoclonal antibodies
✅ Uses of monoclonal antibodies: -
Treating cancer
-
Pregnancy tests
-
Detecting diseases
🦟 Malaria
✅ Caused by a protist (Plasmodium), spread by mosquitoes
✅ How to prevent malaria:
-
Using mosquito nets
-
Draining stagnant water
-
