Document Summary
Biology: the scientific study of life: living organisms include: humans, animals, fungi, plants, bacteria, algae, and protists, properties of living organisms b. i. 1) Order; highly organized and complex (i. e. dna) b. i. 6) The understanding of biology is important: biotechnology (i. e. study of bacteria, medicine, disease / cancer for treatment. The scientific method: observation, question, hypothesis revise, prediction , experiment repeat. 12 1 16 14: a proton is a hydrogen ion g. i. Electron shells: electrons orbit atoms at specific distances: 1st (inner) shell holds up to 2 electrons maximum, all subsequent (outer) shells hold up to 8 electrons maximum, not all atoms have full electron shells! c. i. Reactive: requires electrons to satisfy their outer electron shells (i. e. hydrogen) c. ii. Non-reactive: have full outer shells (i. e. neon) c. ii. 1. Chemical bonds and molecules: chemical reactions enable atoms to give up or acquire electrons to complete their outer shells. a. i.
