Biology 4/5 for the international student has been developed for the world student. This six book series has been written by an experienced international author team and will benefit students studying the International Baccalaureate MYP. The series has been carefully crafted to ensure students develop a global view of science.

Biology 4/5 for the international student presents eight biology units. The unit question, significant concepts and Area of Interaction focus are identified at the beginning of each unit.
Each unit features:
• content ensuring progression to the IB Diploma programme
• clear, well-explained text
• flexibility that allows schools to develop a programme suitable for their needs
• assessment tasks identified
• student reflection built into each unit
• progressive development of scientific inquiry through experiments and investigations addressing Criteria D and E
• suggestions for Criterion A science activities
• icons indicating the development of Approaches To Learning, Learner Profile and science specific skills
• What do you know? question sets throughout each unit addressing Criterion C
• highlighted new terms and end-of-unit glossary
• hands-on learning activities suitable for class or home
• literacy activities assisting students in developing communication skills
• end-of-unit review questions incorporating a range of question types suitable for assessment of Criterion C

An interactive student CD-ROM is packaged with every course book. The CD-ROM contains:
• an electronic version of the course book
• Let's use Technology activities and worksheets
• short animations to assist student understanding of difficult concepts
• interactive student self-tests
• links to Work on the Web activities

tucked away inside your chest cavity, they cannot see what you are doing or know if there is any danger. So they need to be ‘told’ when you need them to work faster or slower. Suppose you are power walking. The muscle cells in your legs need glucose and oxygen to be supplied at a rate that is keeping up with how hard they are working, otherwise they will not have enough energy to keep contracting and relaxing. To bring more oxygen to these cells, and to remove the extra carbon dioxide waste they

of branches. Each branch connects the neuron with another neuron. At the other end of the neuron is an axon, a long hair-like extension that carries messages away from the cell body to another neuron. The axons of many neurons are covered by a fatty insulating layer known as a myelin sheath. The sheath protects and insulates the nerve fibres and increases the rate of transmission of the nerve impulses. The myelin sheath is formed by many individual cells, which look like cylinders with tiny gaps

What is DNA and what does it do? 3 ‘Binary’ means it consists of two. ‘Fission’ means splitting. Explain why binary fission is a good name for the process. 4 Imagine that a single bacterium lands in an open carton of milk. After half an hour, it splits in two and becomes two bacteria. After another half an hour the two bacteria become four. Draw a graph to show how the numbers grow over five hours. 5 Explain why regeneration can be useful for the survival of a species. 79 ISBN 9780170185110

opposite poles of the cell. • Cytokinesis begins. The mechanics of meiosis You have already seen that each cell contains a maternal and a paternal copy of each chromosome. A special kind of cell division is needed to produce the haploid genomes found in the gametes. This process is called meiosis (a Greek word meaning ‘diminishing or reducing’) and takes place in the testes of males and the ovaries of females. These organs are collectively termed gonads. A quick glance at Figure 5.13 shows that

theories on evolution? Can people believe two apparently contradictory theories at the same time? 4 Why is evolution still a controversial issue for some people? Assessment Task 5 (Criteria B and C) activity Guiding question: How does continental drift affect evolution of species in the biosphere? Task: In small groups, study the divergent evolution of a modern-day species and its possible ancestral link (e.g. emu, ostrich, and rhea). Write up a report in a form agreed to with your teacher.
