PDF of comparison between Natural and Agricultural Ecosystems

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.

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.

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

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