SOME USEFUL WORD ROOTS FOR BIOLOGY: As we go through the semester, can you put some words we use next to these word roots? “di” or “dy”– two “bi” – two “-ose” – sugar “-ase”- enzyme “poly” – many “mono” one “eu” –true “kary” – kernel (nucleus) “pro”- before “-phobic” - fearing “-philic” – loving “endo” - within “ex” –out “lysis” break apart “pseudo” – false “pod”, “podia” – feet “cephalo” head “hypo” – low “hyper” –high, excessive “allo” – other “glyco-” sugar “an” – without “aero” – air (oxygen) “oxy” -oxygen “hemi” half “homo” – same “hetero” different “pheno”- show or see “photo”- light “auto” – self “troph”- feed “hydro” water “morph” – form or structure “co”- together “intra” within “inter” between “de”- remove 1

The process of science I. Discovery Science A. What is it? Discovery of new information based on what we can record, measure, or observe B. Examples 1. Animal behavior 2. Anatomy C. Inductive reasoning – reasoning from specific observations or experiments to form general theories. II. Hypothesis-Driven Science (Scientific Method) A. What is it? Discovery beginning with a specific question. B. The steps: 1. Observation 2. Question 3. Hypothesis – tentative answer to our question 4. Prediction – if, then statement 5. Perform a controlled experiment – compare based on only one variable 6. Analyze the results 7. Conclusion – support or doesn’t support hypothesis C. Mimicry example 2

1. Observations – a. Jumping spiders wave their legs around competitors b. Flies wave their wings when approached by a jumping spider 2. Question – What is the function of the fly’s wing markings and behavior? 3. Hypothesis – The wing markings and the behavior prevent pouncing by the spider 4. Prediction –If the fly’s wing markings prevent pouncing, then masking the markings should increase spider pouncing. 5. Controlled experiment a. experimental group – flies without markings (sharpie marker) b. control group - normal flies c. measure – pounce rate 6. Results a. experimental group – 38% pounce rate b. control group – 20% pounce rate 7. Conclusion- the experiment supports our hypothesis D. Deductive Reasoning – reasoning from general theories to explain specific observations or experiments E. Scientific Theory – a hypothesis that has not been disproved after rigorous testing over many years 3
