Name: _________________________________________ Date Received: _____________ Honors Biology I Midpoint Assessment Review Sheet The biology midpoint common assessment (MCA) consists of 75 multiple choice questions and 5 short answers. The questions are grouped into categories. The midpoint common assessment makes up 10% of your overall grade. It is very important that you take the exam seriously! Studying is not an option, it is required. In order to eliminate stress and students being overwhelmed we are going to take some time to review what we have learned so far to remind you of what is important and what you will need to remember by the end of the semester. Portions of this review sheet will be due throughout the next week. It will be checked on the due date. To get full credit for the review you must answer the questions on a separate piece of paper. Write out detailed answers. Your answers do not have to be in sentences, but they do have to be detailed! Use your notes and the textbook to answer the questions. When you turn in the questions each day you must turn in this paper. I will record your daily grade in the checked column on the timeline below. On the last day I will add up your daily grades to give you a total out of 50. If you turn in questions late you will receive half credit. It is very important that you have the review packet with you and completed. Review Sheet Timeline Chapter 1, 2, & 3 4&5 Due Date Test Points value Points earned 28 23 Chapter 1 Intro to Science 1. Define the levels of biological organization from molecules to the biosphere, noting the relationship each level has to the others. Molecules (DNA), Organelle (nucleus), Cell (nerve cell), tissue (Nervous tiessue), Organ (Brain), Organ system (Nervous system), Organism (brown pelican), Population (Group of brown pelicans), Community (All organisms on Florida coast), Ecosystem (All biotic and abiotic factors of Florida coast), Biosphere (Earth) 2. Explain how cells are the structural and functional units of life. Differentiate between prokaryotic and eukaryotic cells. Cells are the lowest level of structure that can perform all activities required for life. Prokaryotic – lack a nucleus, lack membrane bound organelles (Bacteria) Eukaryotic – True nucleus, membrane bound organelles (plants, animals, fungi, protists) 3. Describe seven properties that are common to all life. 1) Order 2) Regulation 3) Growth and Development 4) Energy utilization 5) Response to the environment 6) Reproduction 7) Evolution 4. Compare the three domains of life. Distinguish between the three multicellular kingdoms within Eukarya. Domain Bacteria – prokaryotes (common bacteria) Domain Archae – prokaryotes (extreme bacteria, halophiles, methanogens,e tc) Domain Eukarya – eukaryotes (everything else!) 1) Fungi 2) Animalia 3) Plantae 4) Not perfectly defined yet - Protists 5. Describe the process and products of natural selection. Explain why individuals cannot evolve. The selection of beneficial variations of individuals within a population that allow them to survive to reproductive age and pass on their genes. Individuals cannot evolve, only populations can evolve over very long periods of time. 6. Define a hypothesis, and compare inductive and deductive reasoning. Hypothesis – tentative answer to some question. Inductive reasoning – derives general principles from a large number of specific observations. Deductive reasoning – derives specific principles from general observations. 7. Define a control, and describe an example. A variable that does not change through the experiment. For example, washing your hair with water if testing the effects of a specific type of soap. Chapter 2 and 3: Biochemistry and Organic Compounds 8. List the 4 elements necessary for life. CHON 9. Recall matter. What are the particles found in an atom? What is an ion? Isotope? Protons (+), Neutrons (0), Electrons (-). An ion is a charged atom (negatively charged – anion). An ion is a charged atom (positively charged – cation). Isotope: Atoms with the same number of protons but different number of neutrons. 10. All organic compounds contain what element? Carbon 11. Differentiate between a covalent and ionic bond. Sharing of electron/transfer of electrons 12. For each of the following, list the monomers, polymers, and major function in the body. a. Carbohydrates – monosaccharides, c. Lipids – glycerol and fatty acids, polysaccharides. Energy, structure in (triglyceride, phospholipid, steroids, plants waxes) insulation, waterproofing, long b. Proteins - amino acids, polypeptides, term energy storage enzymes, structure, membrane transport d. Nucleic Acids – nucleotides, polymer, DNA and ATP 13. For each of the following, list the type of organic compound it is, whether it is a monomer or polymer, and its major function. a. Cellulose – polymer, carb, plant structure f. Glycerol and 3 fatty acids – monomer, b. Polypeptide – polymer, protein, general lipid, triglyceride protein function g. Starch – polymer, carb, energy storage in c. Glycogen – polymer, carb, energy storage plants in humans h. Phospholipids – monomer, lipid, cell d. Polysaccharide – polymer, carb, energy membranes e. Disaccharide – polymer, carb, energy i. Wax – monomer, lipid, coatings/protecting j. Glucose – monomer, carb, energy 14. Differentiate between hydrolysis and dehydration synthesis. Include which one makes bonds and which one breaks bonds, and also which one stores energy and which one releases energy. Hydrolysis – adding a water to break polymer, release energy Dehydration synthesis – remove water to build a polymer, energy storage. 15. Why doesn’t oil and water mix? Polar/nonpolar 16. Explain acids and bases using the pH scale: a. 0-7 acid, 7-14 base Chapter 4 and 5: Cell Structure & Function 17. What is the role of enzymes in the human body? speed up reactions 18. List the 3 components of cell theory. 1)All living organisms are composed of cells 2) Cells are the basic structure and function of all living things 3) All cells come from pre-existing cells 19. Differentiate between prokaryotic and eukaryotic cells. Give an example of each. Pro – single celled, no membrane bound organelles, bacteria. Eukaryotic – multicellular, membrane bound organelles, everything else 20. What is the function of each of the following organelles? a. Nucleus – control center, houses DNA g. Lysosomes contains digestive enzymes to b. Cell Membrane serves as out barrier, remove wastes regulates what enters/exits the cell h. Golgi apparatus ships, packages, and c. Ribosomes – makes proteins modifies proteins and lipids d. Mitochondria powerhouse of the cell, site i. Vacuoles of cellular respiration Contains water and storage of materials, only in plants e. Chloroplasts site of photosynthesis, contains chlorophyll f. Rough endoplasmic reticulum holds ribosomes, transports lipids and proteins 21. What organelles are present in a plant cell that are absent in an animal cell? Chloroplasts, cell wall, vacuole 22. What are the four levels of organization from simplest to most complex? cell, tissue, organ, organ system 23. Define the following terms: j. Solution substance in higher concentration, dissolves solutes (usually water) k. Diffusion movement of substances from high to low concentration (across cell membrane) l. Osmosis movement of water from high to low m. passive transport cell transport from high to low requiring no energy n. active transport cell transport from low to high requiring energy o. facilitated diffusion passive transport (high to low) requiring a protein (large, charge substances) p. endocytosis movement of large particles into the cell q. exocytosis movement of large particles out of the cell 24. Draw an example and describe what would happen in cells of the following solutions: hypertonic – more solute surrounding the cell, water moves out, cell shrinks, hypotonic more solute in the cell, water moves into cell, cell swells or shrinks, isotonic equal amount of solute in and out of cell, equal exchange of water in and out of cell
