Biology 12 Mid Year Overview 2015 The mid year will be worth about 70-80 marks Prescribed Learning Biology 12some short answer Expect mostly Outcomes: multiple choice with Name: __________________ Date: ___________________ Block: ______ Prescribed Learning Outcomes for Biology 12: Processes of Science 1. demonstrate safe and correct technique for a variety of laboratory procedures 2. design an experiment using the scientific method ( identify and control variables) 3. interpret data from a variety of text and visual sources (apply & use to graphs, tables, diagrams etc) Cell Biology Cell Compounds and Biological Molecules- Chap 1-2 1. describe the characteristics of water and its role in biological systems 2. describe the role of acids, bases, and buffers in biological systems in the human body 3. analyse the structure and function of biological molecules: – carbohydrates – lipids – proteins – nucleic acids 4. identify structural diagrams and monomers / polymers / hydrolysis /synthesis of biological molecules Cell Structure- Chap 3-4 4. analyse the functional inter-relationships of cell structures & identify cell structures on diagrams & electro micrographs (plasma membrane, cell wall, nucleus, nucleolus, nuclear envelope, ribosomes, vesicles, ER, Golgi Body, Lysosomes, chloroplasts, mitochondria, cytoskeleton, centrioles) Transport across Cell Membrane Chap 4 5. analyse the structure and function of the cell membrane using the fluid mosaic model & active vs passive transport -ID/describe: phospholipids, glycolipids, cholesterol, peripheral proteins, integral proteins, glycoproteins -compare contrast types of transport across the membrane (diffusion, osmosis, active, passive, endo & exocytosis) explain why cells divide when they reach a particular surface area-to-volume ratio DNA Replication- Chap 25 p505-509 6. describe DNA replication- identify enzymes & steps involved 7. identify & label components of DNA (nucleotides, nitrogenous bases, sugars, phosphate, H-bonds) Protein Synthesis Chap 25 p 51-0-516, p 520 8. demonstrate an understanding of the process of protein synthesis Transcription & Translation -define and identify vocab: gene, DNA, mRNA, rRNA, tRNA, codon, anticodon, RNA polymerase, 9.explain how mutations in DNA affect protein synthesis (examples of mutagens and point vs frameshift mutations) Enzymes- Chap 6 p 108-111 10. analyse & explain the roles of enzymes in biochemical reactions -explain how enzymes affect reaction rates using the lock and key / induced fit model -analyse and explain factors that affect enzymatic speed (temp, pH, substrate & enzyme concentrations, inhibiton, cofactors & coenzymes) Human Biology Digestive System 1. analyse the functional inter-relationships of all structures of the digestive system 2. describe the components, pH, and digestive actions of salivary, gastric, pancreatic, and intestinal juices 3. explain the role of hormones in digestion and in maintaining blood sugar levels (homeostasis) 4. compare and contrast chemical and physical digestion throughout different locations along the digestive tract 5. apply knowledge of structures & organs to explain digestive system conditions / disorders Circulatory System 6.describe the inter-relationships of the structures of the heart, direction of blood flow and the cardiac cycle (heart beat) 7. analyse the Prescribed relationship Learning between heart rate andBiology blood pressure Outcomes: 12 8. analyse & describe the functional inter-relationships of the 5 vessels of the circulatory system -arteries -arterioles -capillaries -venuoles -veins 9. explain various circulatory system disorders and conditions (hypertension, hypotension, varicose veins, heart murmur) Practice Questions- use your old checklists & you can access old provincial exams at: http://sd67.bc.ca/teachers/barcuri/Bio%2012/provincialexams.htm OR https://www.bced.gov.bc.ca/exams/specs/resource_exams/biology.htm Short Answer Qs:1 .
