Biodiversity, examples of extinctions, causes of extinctions.

A PPT resource used in a lesson about anaerobic respiration - the formation and fate of lactate/lactic acid. Also comments on other anaerobic pathways eg. use of creatine phosphate.<br /> <br /> Used for Edexcel Biology or SNAB, but may be useful in OCR.<br /> <br /> The questions referred to at the end are from the SNAB text book.

This document contains the specification of the Edexcel Biology or SNAB (Salters Nuffield Advanced Biology) A2 course. What I have then done is look through the exam papers up to June 2013 and linked in the questions from these papers to the specification points where possible.<br /> <br /> It has been very useful in providing to students to help them with their revision for specific areas, but also in planning by accessing and using the questions as plenaries/starters in lessons.<br /> <br /> It includes the specification points from Topic 5, 6, 7 and 8 for the exams 6BI04 and 6BI05. Also includes reference to the pre-release material questions from the Unit 5 paper. <br /> <br /> Any feedback gratefully received.
