Key Ideas

10 Different types of multicellular organisms have different roles in an environment.

15 Human actions have significant impacts on interactions within an environment.

22 The activity of organisms changes the environment.

10 Different types of multicellular organisms have different roles in an environment.

11 Malfunctioning in one system or part of a system may affect the whole organism.

13 Abiotic and biotic factors in an environment influence the size of populations and the composition of communities.

26 The genetic variation within a population determines its long-term survival.

3 There are different types of cells and the ways they are organised influences their functioning.

5 Cell division is an integral part of growth and reproduction.

• Living things employ a variety of reproductive strategies.

20 Human understanding of the mechanisms of reproduction and DNA structure and function have led to intervention in natural processes.

24 In most organisms, code instructions within the DNA molecule account for their inherited characteristics.

25 During reproduction DNA is passed from parent(s) to offspring.
