Bio 111
Chapters 1 to 4
| Question | Answer |
|---|---|
| What is Biology | The study of life |
| Cellular Level | atom, molecule, organelle, cell |
| Organismal Level | cell,tissue,organ,organ system,individual |
| Ecological organization | Individual,population,species,community,ecosystem,biosphere |
| metabolic process | sum of all chemical reactions in an organism, controlled by genes |
| chemical reactions | nutrient uptake and processing, waste elimination |
| responsive process | irritability,individual and population adaptation,evolution |
| Growth | reaction that increases the size of an organism |
| Reproduction | reaction that results in the increase in number of individuals in a population |
| control process | coordinates and regulates chemical reactions |
| homeostasis | maintaining constant internal conditions |
| Evolution | Any gradual change |
| Darwin,Wallace | Proposed natural selection |
| Natural Selection | better traits of a species being passed through genes over time |
| Aristotle | First to classify organisms based on structural simalarities |
| Linneaus | Father of Taxonomy |
| Binomial Nomenclature | every species has a unique two word latin name called Genus species |
| Taxonomic System | 8 major ranks with subdivisions, to reduce confusion to common names |
| Human Heirarchy | eukarya,animalia,chordata,mammalia,primate,hominidae,Homo sapien |
| Reproductive Isolation | individuals capable of breeding freely with each other but not with members of other species |
| Biological Species Concept | reproductive islation, unity of life, diversity of life, form fits function |
| Unity of Life | All life has DNA |
| Diversity of Life | There are many adaptations of DNA |
| Science | process of arriving at a solution by testing possible solutions |
| Deductive Reasoning | Applies general principles to predict specific results |
| Inductive Reasoning | Uses specific observation to construct general scientific principles |
| Scientific Method | method of gaining facts by formulating possible solutions and testing them in 8 steps. |
| Matter | anything with mass and volume, composed of atoms and molecules (gas,liquid or solid) |
| Mass | Quantity of matter in an object |
| weight | amount of force with which objects are attracted by gravity |
| atom | smallest unit of element |
| element | units of matter that cannot be broken down |
| molecule | smallest unit of a compound, 2 or more atoms |
| compound | material formed from two or more elements in which elements always combine in the same proportions (H2O) |
| Molecular Weight | sum of atomic weights of the atoms in a molecule |
| Dalton | Atomic Theory |
| Atomic Theory | proton+, Nuetron0, electron- and orbits nucleus |
| Periodic Table | 92 elements, all nuetral |
| Ionic Bond | bonds between atoms of opposite charges |
| Covalent Bond | bonds between atoms that share electrons |
| Hydrogen Bond | bonds between molecules, usually polar |
| Isotopes | atom of same element with different number of nuetrons |
| Radioactive Isotope | unstable and disintergrate over time releasing subatomic particles |
| Half-life | amount of time required for a half an isotope to disintergrate |
| Octet Rule | Second energy level holds a max of 8 electrons |
| Valence Electrons | electrons in outermost shell, contain most energy |
| Ions | atoms with charges that are formed when electrons are transferred from one atom to another |
| Cation | Positive charge(less one electron) |
| Anion | Negative charge(add one electron) |
