4 features shared by all cells - 1. surrounded by plasma membrane 2. contain cytosol (semifluid aqueous interior) 3. all cells contain chromosomes that canary information in the form of DNA 4. all cells have ribosomes (synthesis of protein, synthesis takes place) adhesion - water sticks to other polar substances that it can bond hydrogen to animalia - multicellular eukaryotes that ingest other organisms are the electrons of water shared equally - no, the electrons spend more time orbiting oxygen chemical structure of water - 2 H are covalently bonded to one oxygen cohesion - water molecules stick together due to hydrogen bonds advantage: insects walks on water domain archaea - live in the most extreme environments domain bacteria - the most diverse and widespread prokaryotes and are now classified into multiple kingdoms evaporative cooling - as a liquid evaporates, the surface of the liquid that reminds behind cools down evolution - process by which species change over time as they descend from a common ancestorexplain the relative stability of the ocean temperature - fungi - nutritional mode of its members which absorb nutrients from outside their bodies mushrooms, mold heat of evaporization - quantity of heat a liquid must absorb for 1g of it to be converted from the liquid to gaseous hydrogen bonds - weak attraction between h2o molecules levels of organization within cells - 1. chemical or molecular 2. organelle 3. cell levels of organization within multicellular organisms - 1. tissue 2. organ 3. organ system levels of organizations among organisms - 1. population 2. community 3. ecosystem 4. biosphere` plantae - terrestrial multicellular eukaryotes(land plants) that carry out photosynthesis protista - mostly unicellular eukaryotes and some relatively simple multicellular relativesmostly aquatic solvent - dissolving agent of a solution surface tension - a measure of how difficult it is to stretch or break the surface of a liquid what are the characteristics of life? - 1. organization 2. responsiveness/sensitivity 3. homeostasis 4. reproduction 5. evolutionary adaptation 6. growth and development
