Health is the state of physical and mental well-being. Factors can work together to both physical and mental health. A disease is a disorder that affects an organism’s body, organs, tissues or cells.

Reproduction occurs in all organisms. DNA is important, as it allows new proteins to be synthesised. Mutations in the DNA can have serious implications.

Ecologists study the distribution of living organisms in habitats to find out how healthy it is. They use many different sampling methods to provide quantitative data which is then analysed.

The development of drugs is a long, complicated and expensive process. Monoclonal antibodies are identical copies of an antibody. They are used in pregnancy tests and in cancer treatment.

Hormones are vital to enable sexual reproduction in humans. There are a range of hormones that interact to cause puberty in males and females, and to prepare a woman’s reproductive system for pregnancy.

A non-communicable disease is not passed from one organism to another. They are not infectious.

Homeostasis is the regulation of internal conditions inside cells or organisms, to create the optimum conditions for biological function.
