Bio 100 Lab Quiz #1 Exam Questions And Answers

Qualitative - ANS qualities of an object: color, size (large, small), shape & texture Quantitative - ANS quantity, size (measured) of some aspect of object in question Discovery Science - ANS observations are made and recorded (example, Charles Darwin on the Origin of Species) Hypothesis Driven Science - ANS observations drive questions and seek explanations Scientific Method - ANS formulation of ideas (based on knowledge), testing of ideas, using an experiment, and observing data to determine relationships and drawing conclusions Metric System - ANS Units are based on multiples of ten, to convert units you move decimal points or add zeroes. Larger - smaller unit: move decimal place to the right. Small - larger unit: move decimal place to the left Working Distance - ANS distance between objective and specimen. As magnification increases, working distance decreases Field of View - ANS the amount of the specimen you can see at any one time. As magnification increases, field of view decreases Depth of Field - ANS as you move the focus knobs the stage moves up and down. You are changing the plane in which you are focusing. The higher the magnification, the shorter the depth of field. This movement of the stage up and down while you focus is termed through focusing. Total Magnification - ANS to determine at what magnification you are viewing the specimen, you multiply the ocular (10x) by whatever objective you are using (4x, 10x, 20x, or 40x) e.g. 10x ocular X 4x objective = 40X total magnification Three Domains - ANS Bacteria, Archaea, Eukarya Bacteria - ANS true bacteria - no membrane bound nucleus (Prokaryotic) - unicellular, photosynthesis/ absorption, most have cell walls Archaea - ANS Prokaryotic, unicellular, absorption, cell walls Eukarya - ANS true nucleus (membrane bound organelle containing DNA), unicellular or multicellular, absorption, ingestion or photosynthesis Diversity of Life - ANS Domain, Kingdom, Phylum, Class, Order, Family, Genus, Species Kingdoms - ANS Bacteria, Protista, Fungi, Plantae, Animalia Bacteria - ANS unicellular, absorption, no nucleus or other membranebound organelles (Prokaryotic). Most have a cell wall Protista - ANS unicellular (some multicellular); absorption, ingestionand/or photosynthesis; mostly motile. Some have a cell wall Fungi - ANS multicellular (some unicellular), mostly non-motile,absorption of nutrients. Cell wall Plantae - ANS multicellular, photosynthesis, non-motile, Cell wall Animalia - ANS multicellular, ingestion, motility varies Protists, Plants, Fungi, Animals - ANS Eukaryotic (True nucleus)
