Human Biology: Concepts & Current
Issues --> CH.1-3 --> Exam #1
living - ANSto have the 7 characteristics of life
organism - ANSan individual animal, plant, or single celled life form
cell - ANSthe smallest structure that shows all the characteristics of life
domain - ANSthe highest level of taxonomic classification
genus - ANSone of the level of taxonomic classification
species - ANSthe smallest classification of life
atom - ANSsmallest particle of an element that exhibits the properties of that element
molecule - ANSparticle consisting of two or more atoms joined together by chemical bonds
tissue - ANSa group of similar cells specialized to perform a specific function
organ - ANSa part of the body formed of 2 or more tissues and adapted to carry out a
specific function
organ system - ANSa group of organs that together serve a broad function important to
survival
population - ANSa group of individuals of the same species that occupy the same
geographic area
community - ANSarray of of several different populations that coexist and interact
ecosystem - ANSall living organisms, all matter, and all energy in a given environment
scientific method - ANSobserve, form hypothesis, make a testable prediction, conduct
experiment, obtaining data, accept or reject hypothesis, repeat as necessary
hypothesis - ANSan explanation or description of a proposed truth
prediction - ANSthe act of making an educated guess as to the outcome of something
results - ANSinformation obtained through experiments or tests about a certain topic
fact - ANSa thing that has been proven true through experiments and test
, theory - ANSa main hypothesis that has been extensively tested and explains scientific facts
that are reliable
critical thinking - ANSthe objective analysis and evaluation of an issue in order to form
judgement
what are the 2 things science is - ANSknowledge and process
what are the molecules of life - ANSproteins, carbohydrates, lipids, and nucleic acid
what are the 7 characteristics of living things - ANShaving different molecular structure than
non-living things, require energy and raw materials, are composed of cells, maintain
homeostasis, respond to external environment, grow and reproduce, evolving
genus of human - ANShomo
species of human - ANSsapiens
what are scientific characteristics that make humans a unique species - ANSbipedalism,
opposable thumbs, large brain, language
element - ANSsubstance that cannot be decomposed into simpler substances by chemical
means, and is made up of atoms all with identical number of protons.
carbon - ANSC; the backbone of all organic molecules
hydrogen - ANSH; part of all organic matter and of water
oxygen - ANSO; part of water and most organic molecules
nitrogen - ANSN; component of proteins and nucleic acid
calcium - ANSCa; constituents of bone and essential for muscle and nerve action
phosphorus - ANSP; part of cell membranes and an energy source
iron - ANSFe; a constituent of hemoglobin (oxygen-carrying molecules)
sodium - ANSNa; the primary ion in bodily fluids
potassium - ANSK; important in nerve action
sulfur - ANSS; structural component of most proteins
chlorine - ANSCl; components of digestive acid and major ion in bodily fluids
magnesium - ANSMg; important for the action of certain enzymes and muscle contractions
