APPENDIX 1: BLANK DRAWINGS

In this section you will find a number of key diagrams from this study guide. These blank diagrams can help you prepare for the exam in two ways:

  1. You can use them to practise your drawing and labelling skills. You may be asked to draw a diagram in the exam, so make sure you follow the guidelines set out on page 113 when you redraw and label a diagram.
  2. These diagrams are a valuable study aid. They summarise key information and important processes in Life Sciences. If you can label all these diagrams correctly on your own, without looking at them in the text, you’ll be well prepared for the exam.

The following diagrams are included:

Topic 1: DNA: The code of life

  • Nucleotide
  • DNA
  • RNA
  • Replication of DNA
  • Protein synthesis

Topic 2: Meiosis

  • Homologous chromosomes
  • Stages in meiosis I
  • Stages in meiosis II

Topic 3: Reproduction

  • Male reproductive system
  • Sperm cell
  • Female reproductive system
  • Hormonal control of the menstrual cycle
  • Fertilisation and gestation

Topic 4: Responding to the environment: humans

  • Brain
  • Neuron
  • Reflex arc
  • Eye
  • Accommodation
  • Pupillary mechanism
  • Ear

Topic 5: Human endocrine system

  • Name, position and functions of glands

Topic 6: Homeostasis in humans

  • Skin regulating temperature on a hot and cold day

Topic 7: Evolution

  • Characteristics we share with the African apes
  • Characteristics that make us different from the African apes
