My class have identified three areas in each of Unit 3 and Unit 4 that they would like to do more work on before the exams:

Unit 3: Signatures of Life

• Photosynthesis – Light dependent and light independent reactions
• Respiration – Aerobic and anaerobic
• Immunity – Active/Passive, Natural/Induced

Unit 4: Continuity and Change

• Stages of mitosis and meiosis
• Hardy-Weinberg principle and from Boundless Biology
• Mutations – insertions, deletions, substitutions, frame shift
