Biological Sciences Review Magazine Volume 31, 2018/19 Issue 1

Product Information

In an effort to placate Mr Lovebird, you help clear up the mess. He insists you return each bird to its own aviary. He explains in great detail what you need to do. You realise that he is still very angry with you. Assigning each budgie to the correct cage is not a problem as there are simply four colour types: green, blue, yellow and white (see Figure 1). You spend the whole day putting everything to rights, and even Mr Lovebird is forced to concede that you have done a fantastic job. Within a few days Mr Lovebird has calmed down, and you are delighted when he withdraws his threat to dismiss you. Your organisation does not have access to this article.

As a readable, highly visual magazine, it contains a lively mix of authoritative articles and topical columns, all directly relevant to A-level specifications, Scottish Highers and first year undergraduate courses.The two GCSE magazines – Wideworld (Geography) and Hindsight (History) – are available as a standalone subscription or cross-searchable as an add-on subscription to the A-Level Review magazines. Why do we need a heart? Once organisms reach a certain size it becomes impossible to exchange nutrients and waste products directly with the environment. Instead, a transport system must continually replenish the body tissues with fresh nutrients and remove waste products. In animals, blood is driven through the vascular system by the heart, which is therefore essential for the operation of the body’s transport system.

Coverage is broad, ranging from genetic engineering to conservation, from evolution to photosynthesis, from population control to the function of joints. Janette Parry - Advanced Practitioner, Science/Health Care & Education, Trafford College, Manchester Each magazine is produced by an editorial board made up of specialists in their field, many based at prestigious universities. The average human heart is about the size of a large clenched fist. It sits in the chest cavity (thorax), between the lungs. The heart comprises two pumps that operate together during the heartbeat or cardiac cycle. The systemic side consists of two chambers — the left atrium and the left ventricle — and the vessels that take blood to and from all (except one) parts of the body (see Figure 1). The pulmonary side consists of the right atrium and the right ventricle and the vessels that take blood to and from the lungs. The left side of the heart is more muscular than the right because blood is pumped over long distances. Your organisation does not have access to this article. University tutors frequently use articles and columns as a basis for tutorial assignments, while A-level examining boards have used material from the Review in their questions.

About the magazine

Over more than three decades the Biological Sciences Review has become a major resource for all students and teachers of the biological sciences. You have been working at Mr Lovebird’s Pet Emporium over the summer to earn some money while waiting to start studying for your genetics degree. Suddenly you receive a tweet. Mr Lovebird is in a flap. It has been a disastrous night. Someone forgot to close the aviaries housing the prize-winning budgies, and when Mr Lovebird arrived at the shop early in the morning, a scene of utter chaos confronted him. Budgies were everywhere! The budgies are Mr Lovebird’s pride and joy and he is mortified. He blames you, threatening to terminate your employment. The magazine is published by Hodder Education, and its editorial home is at the University of Liverpool. Aims and Objectives
