Cards Term Biology Definition Study of life Term 7 Characteristics of life Definition Organization, take in materials and energy, homeostatis, response to stimuli, growth and development, adaptation, and reproduction Term Levels of organization Definition atoms, molecules, organells, cells, tissues, organs, organisms Term a cell is unique why Definition The simplest structure to have all the characteristics of life. Term Explain how both plants and animals take in materials and energy. Definition Humans have food for both Plants have light for energy and for material they have H2O(water), CO2 (carbon dioxide) & minerals. Term Homeostasis Definition fairly constant internal conditions Ex: body temperature, pH level, blood sugar, amount of water in body, etc. Term Growth and development Definition Growth - increase in mass Development - control of growth Term Adaptation Definition Strucutres and functions suited to a particular environment (ex: bird has hollow bones for flight, and frogs have clear eyecover to swim with) Term Reproduction Definition critical for a population to maintain itself. Term Taxonomy Definition classification and naming of organisms. Term Classifications of organisms Definition domain, kingdom, phylum, class, order, family, genus, species. Term Kingdoms (domain Eukarya) Definition Protista, Fungi, Plantae, Animalia Term Protista Definition single celled - simple multicellular Term Fungi Definition external digestion Term Plantae Definition produces their own food Term Animalia Definition internal digestion Term Science Definition an attempt to understand the physical characteristics of the world around us based on physical evidence. Term Explain the Scientific Method Definition Observation - have to question and observ then answer from that a hypothesis which is subject to change. Next test the hypothesis by more observation, experiments, and collecting data. Modify the hypothesis (sometimes it is right to begin with) next bring to a conclusion and form a theroy (also can be subject to change) Term Hypothesis Definition statement/idea that has a low level of confidence. Term Theory Definition concept suported by a large amount of physical evidence Term Technology Definition the application of science Term Science & technology responsiblity Definition everyone in a society needs to be able to make informed decisions about the application of science/technology. Term Science & religion Definition science deals only with materials & it cannot be the basis for moral decisions. Term Functioning societys Definition must a variety of philosophies such as science, religion, art, etc. Term Atom Definition Samllest particle to have all characteristics of an element. Term Nucleus Definition two particles a proton (positive electrial charge) and a neutron (neutral, no charge) they btoh contribute to the mass of an atom. Term Electrons Definition orbit the nucleus in layers called shells. the particles have a negative charge and they are too small to contribute to the mass of the atom. Term Element Definition Substance composed of only one type of atom. Within an element all the atoms have the same # of protons. Term How many naturally occur elements are there Definition 92 naturally occuring ones and 109 elements in total Term what basic elements make up 98% of a typical organism Definition C,H,O,N,P,S Term Identify #1-3 Definition 1. Atomic number 2. Element 3. Atomic Mass Term Atomic number Definition the number of protons in an element Term Atomic mass Definition number of protons plus the number of neutrons Term Isotopes Definition atoms of the same element with different atomic masses Term explain the placement of electrons in shells. Definition electrons must equal number of protons. the first shell holds only 2 electrons, and all other shells hold up to 8. Term Octet rule Definition atoms will react(bond) with one another in order to attain a filled outer shell (exception to H & He)
