Accuracy

1 of 42

The closeness of a measurement to the true value

2 of 42

Adaptation

3 of 42

A characteristic that helps an organism to survive in its environment

4 of 42

Adult cell cloning 

5 of 42

A process in which the nucleus of an adult cell is inserted into an unfertilised egg cell from which the nucleus has been removed, and the cell divides and develops into a new individual

6 of 42

Aerobic respiration

7 of 42

Respiration that requires the presence of oxygen to release energy from glucose, producing carbon dioxide and water

8 of 42

Agar

9 of 42

A nutrient rich-jelly obtained from seaweed used for growing microbes 

10 of 42

Anaerobic respiration

11 of 42

Respiration which does not need oxygen - the release of energy from glucose without oxygen. The process releases less energy than aerobic respiration

12 of 42

Antibiotic 

13 of 42

A chemical compound, often produced by microbes, that destroys bacteria

14 of 42

Antibody

15 of 42

A chemical compound produced by white blood cells when the immune system detects the presence of a pathogen. Antibodies are specific to a particular pathogen, that is, each type of antibody attacks only one type of pathogen

16 of 42

Antigen

17 of 42

A cell marker protein on the outside of a cell. Antigens differ between people

18 of 42

Antiseptic

19 of 42

A chemical compound used to stop the growth of micro-organisms on living tissue

20 of 42

Asexual reproduction

21 of 42

Reproduction from one cell of a parent organism by simple cell division, without fertilisation of gametes, that is, without fusion of male and female sex cells

22 of 42

Auxin

23 of 42

A plant hormone that affects growth, rooting and flower and fruit formation

24 of 42

Bacterium

25 of 42

A single-celled micro-organism without a nucleus. Bacteria can reproduce quickly, and some cause disease

26 of 42

Balanced diet

27 of 42

 A diet made up of a variety of different foods to provide energy and all the nutrients needed to stay healthy.

28 of 42

Biomass

29 of 42

Biological material; in particular, the total mass of living material at a specified level in a food chain or in a specified area

30 of 42

Brain

31 of 42

The centre of the nervous system, responsible for interpreting sensory signals, co-ordinating motor responses and higher activities such as thought and memory 

32 of 42

Camouflage 

33 of 42

Body colouring and/or shape to help conceal an organism in its environment 

34 of 42

Cannabis 

35 of 42

An illegal drug that can produce a sense of euphoria (well being), but also anxiety and loss of short term memory. 

36 of 42

Carbohydrate 

37 of 42

A food type that is the main energy source in the diet. Carbohydrates, for example, sugars and starch, contain only the elements carbon, hydrogen and oxygen. 

38 of 42

Carbon cycle

39 of 42

The way in which carbon atoms circulate between living organisms and the physical environment

40 of 42

Central Nervous system

41 of 42

The brain and spinal cord

42 of 42
