About this deal

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. UK and British International Schools: 2 GCSE titles – Hindsight (History) and Wideworld (Geography) Making sure students are prepared for exams, with advice to support independent research and study skills Janette Parry - Advanced Practitioner, Science/Health Care & Education, Trafford College, Manchester 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.

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. Each magazine is produced by an editorial board made up of specialists in their field, many based at prestigious universities.Topical content: making the latest academic research accessible to students, with articles linked to A-level specification topics The Biological Sciences Review editorial board has commissioned topical and focused new material for the 2023/24 volume, including: Over more than three decades the Biological Sciences Review has become a major resource for all students and teachers of the biological sciences.

No waiting for new issues to be uploaded: digital issues are now published into the eLibrary at the same time as print The magazine is published by Hodder Education, and its editorial home is the University of Liverpool. Aims and Objectives The magazine is published by Hodder Education, and its editorial home is at the University of Liverpool. Aims and ObjectivesThe 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. 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. Access to the A-Level Magazines will give your students the edge they need to achieve their best grades. With specially commissioned topical articles, cutting-edge research and brand-new case studies that will deepen their subject knowledge and help them develop independent learning skills, while revision support and expert exam advice will make sure they know how to perform when it really matters. Coverage is broad, ranging from genetic engineering to conservation, from evolution to photosynthesis, from population control to the function of joints. Contemporary examples from the world of science to be used in the classroom, as part of lesson plans and for revision and stretch-and-challenge purposes

The current volume of the magazines are included in the eLibraries, published online at the same time as the print issues are released, along with issues from previous years from 2009 for the A-Level Review titles, 2006 for GCSE Hindsight, and 2010 for GCSE Wideworld. What institutional subscription options are available for the Hodder Education Magazine elibraries through JCS? Professor Angus Lamond - Wellcome Trust Centre for Genetic Regulation & Expression, University of Dundee 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.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.

A blood sample is the most convenient starting point, using white cells called T lymphocytes. These cells do not usually divide, but are stimulated to do so in liquid suspension. Only a small percentage of cells enter division, so the number is increased by the addition of agents such as colcemid. This disrupts the mitotic spindle, so preventing the separation of daughter chromosomes and holding cells in metaphase. The cells are then swollen in a hypotonic solution, chemically preserved, then burst by dropping them onto a cooled microscope slide, dried and stained. The chromosomes are then sorted into pairs according to size to produce a karyotype. The cells may also be treated to produce bands shown by stains such as Giemsa — G-banding (Figure 1). These bands are used to produce an international standard map for each chromosome known as an idiogram. Preparations can also be prepared for examination in the scanning electron microscope.
