Unformatted text preview: BIO1130 Midterm Examination – October 4, 2008 Name:________________________________________Student #_______________ BIO 1130 A Introduction to Organismal biology Midterm examination Worth either 15% or 20% of your final grade Total points on both parts of the exam is 70 pts Saturday, October 4, 2008 Part B: Written questions a) Place your name and student number in the space provided below. Be sure that your name, or student number, is on the top of each of the following pages – the exam will be separated b) Answer all questions in the space provided on the exam. Do not transfer answers to the back of the page. c) You may use either pencil of ink for your answers. d) Answers as written paragraphs are preferred but point form is acceptable as long as the points are logically organized and not random statements or facts e) This is not an open book exam. f) Please circle your lab section in the table below. This information will be used to return your written exam to you Name: __________________________________________ Student number: __________________________________ Monday Tuesday Wednesday Thursday Friday Week A1- BSC312 A2- BSC312 A3- BSC312 A4- BSC312 A5- BSC312 1 A6- BSC330 A7- BSC330 A8- BSC330 A9- BSC330 A10- BSC330 A11- BSC335 C1- BSC 335 C2- BSC 335 C3- BSC 335 C4- BSC335 Week B1- BSC312 B2- BSC312 B3- BSC312 B4- BSC312 B5- BSC312 2 B6- BSC330 B7- BSC330 B8- BSC330 B9- BSC330 B10- BSC330 B11- BSC335 C5- BSC335 C6- BSC335 C7- BSC335 . Page 1 of 5 BIO1130 Midterm Examination – October 4, 2008 Name:________________________________________Student #_______________ 12 pts Part 1. Briefly explain what each of the following terms means or the biological contribution made by the person. Where possible include an example in your explanation from a group or an organism to which the term or name applies. Charles Lyell {Uniformitarian theory}{ changes in the fossils are gradual and slow}{Layers in the rocks represent different times or intervals}{Geological time scale} Each of these four is worth a point – maximum of three points for the full marks. Ligase {enzyme in DNA replication}{joins DNA fragments}{uses ATP} {joins with a phosphodiester bond} Each of these four is worth a point – maximum of three points for the full marks. Analogy {different embryonic/genetic/structural/ origins}{but same functions/appearance} {example. Most common will be the wings of insects compared to vertebrate wings.}{results from convergent evolution} The terms separated by the slashes are alternate ways that the students may answer this they do not mean that all the terms have to be in the answer. Each is worth a point and the maximum score is three. Transmutation (Essentialists) {Organisms existed as fixed unchanging types that did not eveolve}{mutation created new types of organisms}{no gradual changes new types were spontaneous} One point each part, the idea must be present but it does not need to be worded exactly as worded here. Page 2 of 5 BIO1130 Midterm Examination – October 4, 2008 Name:________________________________________Student #_______________ 20 pts Part 2: Fill in the missing word, or provide the one word answer in the space provided at the end of the sentence. If the line is missing, add it. 2.1. Once the genetic code was found and combined with Darwin's theories and there was an explanation for the unique vital force these two philosophies on what life was were combined. _______________ Organacists 2.2. Kingdom of unicellular eukaryotes. _______________ Protista/protist 2.3. The geological eon that were are currently in. _______________ Phanerozoic 2.4. The science of the scientific revolution studied mostly these types of objects. _______________ Inanimate/Non-living 2.5. A key character that separated the organisms in the Kingdoms that Linnaeus described. _______________ Movement/ Motility 2.6. Polymer subunits. _______________ Monomers/ Biomonomers 2.7. Douglas Adams divides the history of modern science into four ages what was the principle investigative tool of his first age of sand. _______________ Telescope 2.8. Physical sciences deal with this type of material, biologists don't and it is one of the reasons that natural sciences were not a part of the scientific revolution. _______________ Inanimate/abiotic/nonliving 2.9. The major taxa recently changed, and this new one was added at the very top of the scheme. _______________ Domain 2.10. These organisms dominated the Achaean eon _______________ Bacteria/Archaea 2.11. The modern age of science begins with this revolution. _______________ Scientific 2.12. Historical narratives ask this type of question. _______________ Why/Ultimate 2.13. The presence of variation that is based on a genetic program distinguishes this type of Natural science. ______________ 2.14. In this type of review other scientists working in the same area as you look over your manuscript and make recommendation on whether it should be published. _______________ Peer Page 3 of 5 BIO1130 Midterm Examination – October 4, 2008 Name:________________________________________Student #_______________ 2.15. If you don't take enough measurements you result may be subject to this type of error. _______________ Sampling 2.16. Lipids are insoluble in water because they have this polarity property. _Nonpolar/hydrophobic ______________ 2.17. Of hypothesis and theory this is the more general finding that has the broadest application. _______________ Theory 2.18. The type of prediction that a scientist's test of a hypothesis is. _______________ Logical 2.19. In the classification scheme after Kingdom, Phylum, Class comes this taxon. _______________ Order 2.20. The Genus and species names are written in italic because there something different about these words when they're found in a sentence. What's the difference? _______________ Language/Latin/Greek Page 4 of 5 BIO1130 Midterm Examination – October 4, 2008 Name:________________________________________Student #_______________ 12 pts Part 3: Answer the following two questions in the space provided. 3.1 Compare the temperate grassland and temperate forest in terms of temperature, rainfall and vegetation and the limits for primary productivity. (This answer lends itself to a well organized table) When scoring this question there is a point for each cell in the table and there should be two strong points made about variation (seasonality) and levels for rain and temperature. In the last row a point each for describing the vegetation and productivity. Total points (12) divided by two for the final score for the question. Temperate grassland Temperature Rainfall Vegetation/limits of primary Moderate temperature with winter periods below freezing but to extreme. (annual fluctuations) Moderately high precipitation with only moderate variation during the season. Grasses dominate. Too dry for trees, also fires may limit tress. Nutrient rich soils. Productivity low but not the lowest (Less than forest more than boreal) Temparate forest Same as grassland Moderately high precipitation with low variation during the season. There is less variation then the grassland Deciduous/leafy trees that drop leaves in the fall. High productivity between tropical and grassland 3.2 What are transitional forms and which of Darwin’s theories do they provide evidence for, give an example? Transitional forms: {Fossils}{Showing the gradual changes as a species evolves into another form} {Supports the theory of no constancy of species – 2 pts, theory of gradual change 1 pt the first is more accurate}{examples may include: whale, birds, horse, human evolution from primates – stating this is worth a point}{explaining the example properly is worth a point} Points as indicated be sure to place a 2 beside the check that is worth two points.
