  5. Ordersensitivitygrowthdevelopmentreproductionregulation

  6. What are the steps of the scientific method?

  7. Problemhypothesisprocedure/experimentcollect dataorganize datainterpret dataconclude

  8. Darwin’s contribution to the Theory of Evolution

  9. Sailed on HMS BeagleObserved:giant extinct armadillosfinches on Galapagos Is.Fossil beds in S.A.Giant land tortoiseswrote On the Origin of Species

  10. What is Natural Selection

  11. The concept of evolution through natural selection suggestsspecies that are born with favorable traits are more likely to survive and thus more likely to pass on their genetic traits to their offspring, governing the basis for evolution

  12. How are fossils dated?

  13. By using radioactive isotopes of elements with a known half-life – the most common being carbon 14

  14. What is comparative anatomy?

  15. The science of comparing anatomical features of different organisms in hopes to find relationships between them and understand evolution better

  16. What is the difference between analogous and homologous structures?

  17. Analogous – structures have different embryological beginnings, but have the same function (wing of bat – wing of bee)Homologous – structures with the same embryological beginnings, but do NOT have the same function (leg of a horse – flipper of a porpoise)

  18. Sample questions

  19. Darwin was 22 when he began his voyage on the HMS beagle.

  20. Cells are the smallest level of biological organization.

  21. Deductive reasoning is when general principles are found from SPECIFIC cases.

  22. Hypothesis always withstanding the test of experiments is NOT true.D

  23. The scientific process involvesrejection of hypothesis that are inconsistent with experimental results

  24. Darwin was greatly influenced by Thomas Malthus and his “On the Principles of Population”

  25. Bat’s wings and porpoises’ flippers are considered homologous structures

  26. Darwin’s theory of evolution by natural selection Those creatures who possess favorable traits are more suitable for survival and thus have a greater chance of successful reproduction and the passing of their traits to their offspring.

  27. What is an atom made up of?

  28. Protons (positive charged subatomic particles)Neutrons (neutral subatomic particles)Electrons (negative charged subatomic particles)

  29. What are isotopes?

  30. Elements with the same proton number but different neutron number

  31. What are valence electrons?

  32. Outermost electrons orbiting the nucleus of an atom giving the atom it’s chemical characteristics

  33. Periodic Table – arranged according to chemical characteristics and numbered according to the number of protons in the nucleus

  34. Elements strive towards filling their outer shell with the maximum number of electrons (8) – this is called the Octet Rule and it’s one of the characteristics of elements that categorizes them on the PT.

  35. Noble/Inert gases have fulfilled the Octet Rule and are non-reactive with the other elements.

  36. Dimetri Mendeleev constructed the Periodic Table to help organize the known elements of his time.

  37. Waterpolarity – water molecules have unequal charges. The hydrogen “ears” are slightly positive and the oxygen “face” is slightly negative

  38. Water has a high specific heat. It takes a lot of energy to heat up 1 gram of water 1 degrees celsius.

  39. When water evaporates – a great deal of energy (heat) is used to convert it from a liquid to a gas. This process helps to cool our bodies when we sweat.

  40. Water is a powerful solvent due to it’s polar characteristics. It tends to disassociate ions and in turn “dissolves” substances in it readily

  41. Ordinary oxygen has 8 neutrons

  42. Atoms in which the number of electrons does not equal the number of protons are known as ions

  43. An atom of nitrogen has an atomic number of 7, an atomic mass of 14 , and 7 electrons

  44. Carbon has 4 valence electrons available as bonding sites. They are all equidistant

  45. A carbohydrate that is a macromolecule which contains CHO, with a 2:1 ratio between the C:O

  46. Monosaccharides are simple sugars such as glucose, galactose, and fructose. They are “one sugar” molecules.

  47. Disacharides are transport sugars, such as lactose and sucrose

  48. Polysaccharides are long chains of simple sugars, such as starch, chitin, cellulose and pectin

  49. A transport sugar is a disaccharide that can be stored in an organism without being acted upon. They are able to move throughout without being digested.

  50. Starch is a polysaccharide made up of long chains of glucose. It is the form in which plants store glucose
