1.3 Studying Life p17

What is Biology- The study of life.

P18 Name the characteristics of living things. Based on a universal genetic code. DNA=deoxyribonucleic acid Grow & develop. Respond to their environment. Stimulus-signal to which an organism responds. Made up of cells. Reproduce-2 ways. Sexually (2 parents) & asexually (1 parent).

Maintain stable internal environment (Homeostasis) Obtain & use material & energy. Metabolism-build up or break down material. Evolve-change

P20 Name the central themes of biology. Cellular basis of life Information & heredity Matter & energy Growth, development & reproduction Homeostasis Evolution Structure & function Unity & diversity of life Interdependence in nature Biosphere-part of the earth in which life exists including land, water, air & atmosphere. Science as a way of knowing

P22 Fields of Biology Global ecology Biotechnology Building the tree of life Ecology & evolution of infectious diseases Genomics & molecular biology

P24 Performing Biological Investigations How is the metric system important in science? Universal system based on units of 10. Remember safety first!
