Be sure that your name, or student number, is on the top of each of the following pages – the exam will be separated and if you name is not on a page your mark will be zero for that page 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.

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. Georges Cuvier {Fossils show animals have gone extinct}{Catastrophy theory}{things were killed off quickly – biblical flood as an example}{1769-1832 – these dates don’t necessarily have to be there but there should be an indication of when he carried out his work end of the 18th or better yet the start of the 19th century} Each of these four is worth a point – maximum of three points for the full marks. Helicase {unwinds the DNA helix (must state helix for this point)}{Separates the two DNA strands}{creates the replicating fork}{Breaks the hydrogen bonds holding the two strands together} Each of these four is worth a point – maximum of three points for the full marks. Homology {similar embryonic/genetic/structural/ origins}{but different functions/appearance} {example. Most common will be the limbs of vertebrates as fins, wings etc.} {results from divergent 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. Environmental transformation (Essentialist) {Organisms existed as fixed unchanging types that did not evolve}{Lamarck}{Use it or loose it created changes – a reference to environmental factors causing things to appear/disappear and that the appearance/disappearance was passed on to the next generation} 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. This is the preferred investigative method of the physical sciences. _____________ Experiment/test 2.2. Taxon below a phylum but above an order. ______________ Class 2.3. Your text book is an example of this type of scientific literature. _______________ Tertiary 2.4. The glass in fiber optic cables and the speed with which communication and data maybe shared led Douglas Adams' to use it as the hallmark for this age of sand that he proposed to divide up the modern age of science. __________________ Fourth 2.5. The Greek philosopher who is given the title “Father of taxonomy” worked with these organisms. ____________________________ Plants 2.6. Your horoscope is this type of prediction. ______________________ Chronological 2.7. In dates that include BCE, what the CE refers to (two words). __________________ Common era/current era 2.8. Organismal that lived in the past but are no longer living on earth are said to be this. _______________ Extinct 2.9. The percentage of the matter in our solar system that isn't a part of the sun. _______________ One 2.10 Protocells that have been made to date lack this one characteristic of live. _______________ Evolution/self-regulate 2.11. This age separates the revolution and the modern age of science. _______________ Medieval/Dark/Middle 2.12. This philosophy on living things saw them as being made up of small machines. _______________ Physicalists 2.13. In English grammar the Genus name most closely resembles this. _______________ Noun 2.14. If you don't take enough measurements you result may be subject to this type of error. _______________ Sampling 2.15. Lipids are insoluble in water because they have this polarity property. _______________ Nonpolar/hydrophobic 2.16. In its simplest form a historical narrative is this. _______________ Story 2.17. Geological eons are divided into these. _______________ Eras Page 3 of 5 BIO1130 Midterm Examination – October 4, 2008 Name:________________________________________Student #_______________ 2.18. 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 2.19 The kingdom of multicelled saprophytic organisms that have a cell wall composed of chitin. _______________ Fungi 2.20 The organization of the nested categories in Linnaeus’ classification scheme resulted in being referred to as this type of system. _Hierarchical/nested ______________ 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 the boreal 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 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) Boreal forest Average temp is low and varies highly over the year seasonal fluctuations that go very cold in winter, short summers Low, but no evaporation, water locked in the soils Conifers – trees with needles, needles allow early photosynthetic start in spring, or soils poor not enough nutrient to build leaves every year, Productivity is low Rainfall Vegetation/limits of primary 3.2 What is comparative anatomy and which of Darwin’s theories does this provide evidence for, give an example? Comparative anatomy: {Is looking at anatomical characters/traits/morphology and looking for similarities and differences}{To determine how organisms may be related to each other – a statement of grouping organizing relationships is the point here} {Supports the theory of Common ancestry – 2 pts, Gradual change – 1 pt since the first is more accurate }{example: most likely the limbs of vertebrates – stating this is worth a point}{explaining the example properly is worth a points} Points as indicated be sure to place a 2 beside the check that is worth two points.
