2.2.1 Phenylketonuria

The classic example of population screening is testing new-born babies for phenylketonuria (PKU). Individuals with PKU fail to make a protein, a certain enzyme, and develop mental retardation. The absence of the enzyme results in both an accumulation of phenylalanine, which causes the mental retardation, and a deficiency of tyrosine in the body, as shown in Author(s): The Open University

National Geographic-Clown Anemonefish and Sea Anemones

1.1.2 Sexual reproduction

Sexual reproduction includes two distinctive processes:

1. The production of haploid gametes, such as sperm and ova, which involves the specialized nuclear division called meiosis.

2. The fusion of gametes at fertilisation, which results in the restoration of the diploid number of chromosomes.

The relationship between these two processes, and the changes in chromosome number that each process brings about, is

2.2.1 Positive integers: denary numbers

The number system which we all use in everyday life is called the denary representation, or sometimes the decimal representation, of numbers. In this system, the ten digits 0 to 9 are used, either singly or in ordered groups. The important point for you to grasp is that when the digits are used in ordered groups, each digit is understood to have a weighting. For example, consider the denary number 549. Here 5 has the weighting of hundreds, 4 has the weighting of tens and

5.1 Introduction

The land and shallow water experience at least a brief summer at high latitudes, so terrestrial and freshwater ectotherms can be active during warm periods and hibernate when the temperature is below freezing. In contrast, the polar seas are not warmed significantly by the Sun: the mass of water is too large and sea-ice covered in snow reflects sunlight very well. The seawater beneath the permanent sea-ice is continuously at between −1.9 and +6° C, so its inhabitants complete their entire
