Date: ________________ Student: _______________________ Summative o o The entire activity must be completed within the period given unless arrangements have been made with the teacher IN ADVANCE. All work must be completed in class time. Extra reading and research can be done at home but is not mandatory. The experiment sheets will be kept at school. Your task for this investigation is to: DAY 1 – Mon June 3 2013: Create a concept map that explores the information and concepts that are a part of your investigation. This will require research and reading. Describe the scenario you are going to create. DAY 2– Tues June 4 2013: Write a hypothesis for your investigation. Identify the variables. Design a procedure for the experiment you will be conducting. DAY 3– Wed obtain. DAY 4– Thurs June 5 2013: Conduct the experiment; collect and organize the data you June 6 2013: Graph your results. DAY 5– Fri June 7 2013: Analyse your results and write a complete conclusion. SBI3U1 BIOLOGY EXAM REVIEW—MAJOR CONCEPTS AND PRACTICE QUESTIONS PART QUESTION TYPE MARKS A MULTIPLE CHOICE ~50 B ASSOCIATION ~25 C DIAGRAMS ~30 D WRITTEN RESPONSE ~30 Exam Date: Diagrams: Digestive system, respiratory system, mammalian heart, villi (p.263), bacteria, bacteriophage, Paramecium, Euglena, cross section of a leaf. Please write out answers to the topics below and bring any questions you have to your teacher. Use your multiple choice questions in the unit reviews to practice! UNIT 1 Genetic Continuity sexual and asexual reproduction cell cycle mitosis and meiosis—purpose, phases, differences Mendel’s Law of Segregation and Law of Independent Assortment know and apply terms used in genetics: gene, allele, chromosome, chromatids, DNA, dominant, recessive, homozygous, heterozygous, homologous, phenotype, genotype, monohybrid cross, dihybrid cross, purebred, hybrid, , F1 generation, F2 generation, incomplete dominance, multiple alleles #’s and types of chromosomes in males/females, gametes/somatic cells solving problems in genetics using the Punnett square 1. a. Draw a cell 2n = 8 in prophase of meiosis 1. Label spindle fibres, chromosomes, centrioles. How many chromatids? How many homologous chromosomes? What event occurs in this stage? How many chromosomes would an organism with this cell have in each of its gamete cells at the end of meiosis? b. Describe each phase of meiosis. c. Explain the importance of meiosis. 2. In peas, the allele for tall plants (T) is dominant over the dwarf allele (t). a) If you cross a homozygous tall plant and a short plant what will the genotype and phenotype of the offspring be? b) Determine the F2 genotype and phenotype. 3. In peas, the allele for purple flower colour (P) is dominant over the allele for white flower colour (p). Tall plants are dominant to dwarf plants. Cross a purebred tall purple plant with a purebred dwarf white plant. What are the F1 and F2 phenotypic ratios? 6. Black is dominant to brown in guinea pigs while short hair is dominant to long. Cross 2 heterozygous black, heterozygous short guinea pigs and determine the frequency of having brown pigs with short hair. 7. 8. Colourblindness is sex-linked. What are the chances that a colourblind man will have a colourblind son if he has a child with a woman with no history of colourblindness. Show the cross. a. Cross a heterozygous type A with a type O blood. b. What type of blood can a type A person receive? Which blood types can receive type O blood? UNIT 2: Evolution 1. What evidence is there for evolution? Explain. 2. What are the conditions for Hardy-Weinberg equilibrium? 3. Describe the main points of Darwin’s theory of evolution by natural selection. 4. Provide an example for each of the following: a) directional selection, b) stabilizing selection, c) disruptive selection, d) sexual selection 5. What is the current definition of species? What mechanisms exist to prevent species from exchanging genetic information? 6. Name and briefly describe allopatric and sympatric speciation UNIT 3: Internal Systems - CIRCULATORY, DIGESTIVE, AND RESPIRATORY SYSTEMS Structures, Functions, Pathways, Disorders Inhalation and exhalation Comparison between representative organisms Lung capacity (vital, tidal, expiratory reserve) Blood pressure, heart beat (systole, diastole) 1. 2. Trace the pathway of a molecule of oxygen from the outside air into your big toe. Describe what happens to a plate of French fries that you have eaten for lunch. Describe the pathway, chemical and mechanical digestion, activity of enzymes and bile, and absorption etc. 3. Trace the pathway of a red blood cell from the foot to the brain. 4. Describe the regulation of the heartbeat. 5. Compare the digestive system of a cow and a human. Compare the circulatory system of a frog and a human. Compare the respiratory system of a bird and a human. UNIT 4 Diversity of Living Things Classification and binomial nomenclature- reasons for 6 kingdoms—characteristics characteristics of prokaryotes (Archaebacteria and Eubacteria) versus eukaryotes reproduction in Bacteria--binary fission, transformation, conjugation structure of bacteria and viruses bacterial colony shapes and groupings (coccus, bacillus, strepto, staphlo etc.) reproduction of viruses (lysogenic and lytic cycles) major differences between protists, fungi and plants (structures, obtaining energy, life cycle) animal kingdom—body plan, symmetry (radial, bilateral), cephalisation, coelom, segmentation, endoskeleton, exoskeleton, nerve cord, notochord characteristics of major animal phyla UNIT 5 Plants: Anatomy, Growth and Functions 1. 3. Monocots and dicots—general differences Root, seed, stem, leaf structures and functions, seed germination Xylem, phloem—structure and function Transpiration and translocation Photosynthesis vs Cellular Respiration (word and chemical equations) Plant adaptations Tropisms Plant hormones Compare monocots and dicots 2. Compare the function of xylem and phloem. Describe how water is transported throughout a plant, form root to leaves. Use the following words: osmosis, adhesion and capillary action, transpiration. 4. Describe how a plant transports food. 5. Describe phototropism, and geotropism. 6. a. Describe the main features of a leaf (structures and functions). b. How have leaves adapted to different environments?
