Presentation contains instructions for: Reducing sugars tests Non-reducing sugars test Starch test Lipids emulsion test Test for proteins

A workbook for AS and A-Level Biology students (contains Year 12 AS content only). Questions sourced from various AQA past papers. Attached as a PDF with a two-per-page layout (to reduce paper usage) Also included is a PowerPoint version so that you are able to edit it and add or remove topics as you wish. If printing, please remember to print in duplex, with two pages per sheet and in black and white to help maintain the environment. Topics featured: Biological Molecules -ATP -Carbohydrates -Inorganic Ions -Lipids -Monomers and Polymers -Nucleic Acids -Proteins and Enzymes -Water Cells -Cell Recognition and Immune System -Cell Structure -Studying Cells -The Cell Cycle -Mitosis -Transport Across Cell Membranes Organisms Exchange Substances -Digestion and Absorption -Gas Exchange -Mass Transport in Animals -Mass Transport in Plants -Surface Area to Volume Ratio Genetic Information, Variation and Relationships between organisms -DNA and Protein synthesis -DNA, Genes and Chromosomes -Genetic Diversity and Adaptation -Genetic Diversity via Mutation -Investigating Diversity -Species and Taxonomy

A 46 slide PowerPoint presentation about Biological Molecules for AQA A-Level and AS Biology. Topic 1a and 1b. Topics included: -Monomers and Polymers -Condensation and Hydrolysis reactions -Carbohydrates -Monosaccharides, Disaccharides and Polysaccharides -Glucose -Glycogen -Starch -Amylose -Amylopectin -Cellulose -Biochemical Tests (Reducing Sugars Test, Non-Reducing Sugars Test, Starch test, etc) -Lipids -Triglycerides -Phospholipids -Proteins and Amino Acids -Enzymes -Enzyme-Controlled Reactions -DNA and RNA -Nucleotides -DNA Replication and Stages of Semi-Conservative Replication -ATP -Water -Inorganic Ions

PowerPoint presentation about Ecosytems, Biomes, Food Webs, Food Chains, etc.

An 11 slide PowerPoint presentation introducing Stem Cells and Leukaemia. Slides include: What causes Leukaemia? How are bone marrow transplants used to treat Leukaemia? What challenges do doctors face when using stem cells to treat someone with Leukaemia? What is a ‘Graft-versus-host disease’ in terms of Leukaemia treatment and why does it occur? What is the difference between an autologous stem cell transplant and an allogenic stem cell transplant? Are there any advantages or disadvantages of autologous transplants? Are there any advantages or disadvantages of the allogeneic transplants? What is a neo-antigen? Who do we always inherit mitochondrial DNA from? Summary

This worksheet will only take about 10 minutes to fill in and makes for a nice introduction to the biological molecules content. It has a quick fire multiple choice quiz, followed by two past paper exam questions. I would encourage you to check out the accompanying extremely in depth PowerPoint Presentation available on my store, which covers every specification point for Biological Molecules.

This PowerPoint presentation is just a quick Introduction to Dihybrid Crosses and includes a 5 question multiple choice quiz. It introduces the topic with basic knowledge, so might be good as a refresher or introduction, but likely won’t be suitable as a sole lesson.
