| Question | Answer |
|---|---|
| The 6 steps of scientific method | ask the Question, collect Information, make a Hypothesis, Test the hypothesis, make a Conclusion, Submit conclusion for peer review |
| Is natural selection a Random process? | No. All members of a population don't have the same chance to survive. It depends on the organisms adaptations |
| Fact | Something supported by evidence that one would be wrong not to accept,"for now": it is still tentative |
| Theory | The strongest statement that can be made scientifically: it's supported by facts,laws,accepted hypothesis ect... |
| Evidence | material that provides proof\justification for hypothesis,law,fact |
| Natural selection | adaptive evolution: populations of organisms become better adapted to there environment over time giving them a better chance of survival |
| Mutation | a permanent change in DNA: can be good (rare) bad (common) or have no effect |
| Recombination | Offspring of a species receive half of their genetic material from each parent resulting in a new set of DNA with a mixture of genes |
| Science | The collection, study and interpretation of 'Tentative Evidence' of the 'Known Universe' by means of 'Reproducible' experiments and observations |
| What does science try to do? | To find and explain regular patters in nature, to explain regularity in the natural universe |
| Variation within a species | no organisms in a species have the same exact genes (except identical twins) |
| Neutrophil (granular) | usually has many nuclei, and is the first to appear when there is an immune response |
| Eosinophil (granular) | usually has two nuclei (bulbs) and attacks large enemies i.e. parasites |
| Basophil (granular) | usually has one large nucleus and many granules (histamines) on the surface of the cell. inflammatory response usually from an allergic reaction |
| lymphocyte (agranular) | usually has one huge nucleus that fills most of the cell. gives specific immunity for infections like chickenpox |
| Monocyte (agranular) | usually has one large ,often bean shaped, nucleus. largest of the white blood cells. triggers an immune response by displaying parts of enemies on it's surface (macrophage) |
| Erythrocyte (agranular) | has no nucleus. small red cell. carries oxygen and other nutrients to the cells. carries CO2 and waste away from the cells. |
| Atom | the smallest part of an element that still has all of the characteristics of that element |
| Compound | A pure substance made of two or more atoms chemically bonded together |
| Molecule | the smallest part of a compound that still has all of the characteristics of that compound i.e. H2O is a water molecule |
| Mixture | two or more substances that are intermingled but not chemically bonded |
| Electro-negativity | the force of attraction(pull) that an atom has for electrons |
| Specific heat | the amount of heat required to raise the temperature of one gram of a substance. waters specific heat is 1 calorie\gram per degree C. so 1 calorie is needed to Raise the temperature of 1g of water 1 degree Celsius |
| Element | a pure substance where all of the atoms have the same number of Protons (there are 92 naturally occurring Elements) |
| What are some elements of the evolution theory? (8) | Mutation. Variation. Genetic drift. Recombination. Bottleneck effect. Founder effect. Punctuated equilibrium. Natural selection |
| Sampling | Sampling is when a small number of a larger group is used to estimate something about the whole group |
| Sampling error | is a factor of inaccuracy that occurs when collecting a sample that can be cause by any number of things from the location the samples are taken from to the technique used to collect the sample |
| Proton | a positively charged sub-atomic particle weighing one atomic mass unit (AMU) |
| Neutron | a neutral sub-atomic particle weighing one AMU (atoms of the same element with a different number of neutrons are called isotopes) |
| Electron | a negatively charged sub-atomic particle that is not in the nucleus (weighs approximately 1/1850 AMU) |
| Lacuna | a space that contains\contained a cell. (as in bone or cartilage) |
| Canaliculus | a small canal or tube-like passageway, as in bone (plural Canaliculi) |
| Lumen | the canal, duct, or cavity of a tubular organ. |
| Platelets | A cell-like blood product necessary for clotting. clotting factor. Prothrombrin |
| functional group | Alkanes w/ similar structures are grouped into classes; members of each class contain a characteristic atom, or group of atoms, called a “functional group.” |
