Guided Reading Q’s (GRQs)- Do these before the Mastering Assignment.BIOL 101: Guided Reading Questions (GRQs)Purpose: These Guided Reading Questions (GRQs) are designed to help you identify the key concepts in each reading assignment and provide you with a structure to take notes and check your understanding. Learning biology requires your time and attention. Before each class session you will be asked to read from your textbook and answer questions online (Modified Mastering Biology) to assess how well you understand concepts before coming to lecture. These GRQs will help you prepared in a comprehensive and efficient manner.How to answer the GRQs: Research shows that highlighting text and re-outlining the textbook in your notes is not an effective way to learn. You may choose to answer GRQs as you read or you may choose to answer these questions after you read an assigned section. - Do not wait until right before an exam to answer GRQs. - Do use the completed GRQs as a study guide for the exam(s). GRQs – why bother? We know how the brain works! Learning requires repeated interaction with the concepts you are trying to master. These GRQs are designed to give you a structure to not only help you read the textbook but to also study a little bit every day. Research shows this strategy increases the long-term retention of the material and likelihood of success. There is a strong relationship between how much you invest (time and attention) in this class and your academic performance.SOME USEFUL WORD ROOTS FOR BIOLOGY:As we go through the semester, can you put some words we use next to these word roots?If you think of any I am missing, let me know! “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“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”- remove1Guided Reading Q’s (GRQs)- Do these before the Mastering Assignment.Exploring Life and the Process of Science(Read Chapter 1)Reading objectives (you can use these statements later to study in a more open-ended way.)- Define the properties of life- Describe the components of hypothesis-driven science, including controlled and observational studies.- Explain and give examples of the major themes in biology such as: evolution, flow of information,structure and function, transformation of matter and energy, interactions within and between systems1. How would you know if something was alive? (Why is a rock not alive?) What are thecharacteristics that define all life?- Things that are alive reproduce, grow and develop, respond to their environment, use energy,regulate to their environment, and adapt. Living things are also composed of cells. A rock cannot doany of these things therefore it is non-living.What is the smallest unit of life? - A cellOf note, most biologists do not think viruses are “alive” because they cannot grow, process energy,and regulate. But within a host, like you, they can replicate and evolve…so they are a grey area. If youare interested in this, do some google searches on “are viruses alive?” and see some of the debate. 2. Arrange these words in a correct order:community, cell, organism, organ system, biosphere, molecule, tissue, organelle, population, organ, ecosystem- Biosphere, ecosystem, community, population, organism, organ system, tissue, cell, organelle,moleculeConsider the individual properties and uses for a bucket, a piece of rope, or awheel. What happens when you put them together in a system, does a largerfunction emerge? - Yes, they all are pieced together and work together to bring the bucket upor put it down. Similarly, individual tissues can have specific functions, but when put togetherwith other tissue types in certain configurations in organs, new functions arise.This concept is known in biology as emergent properties.3. Review the terms below and define any you need to brush up on:Quantitative Data:- Generally numerical measurements, which may be organized into tables and graphs andanalyzed with a type of mathematics called statistics.Qualitative Data:- Based on recorded descriptions and observationHypothesis:- A testable explanation for a set of observations based on the available data.Experiment: - A scientific test often carried out under controlled conditions that involve manipulating onefactor in a system in order to see effects of changing that factor. 4. How do we prove a hypothesis is true?- A hypothesis cannot be proven but rather data can be collected from the experiments to furtherback a hypothesis and support it. How is a theory different from a hypothesis? - A theory is a very broad assumption that is supported by a large body of evidence, while ahypothesis is much smaller scaled and requires many forms of experimentation. 5. How is science different from other ways of describing and explaining nature, such as philosophyand religion? “the scientific view of the world is based on…(fill in rest of this statement from section1.4)The scientific view of the world is based on hypothesis testing and verifiable evidence.6. What is the main requirement for a scientific hypothesis? - It must generate predictions that can be tested by experiments or gathering further observations. (Note, this is the end of module question from 1.4—these are also very useful review quiz-likequestions during reading and studying).7. Module 1.5 shows us the process of science with a controlled experiment. What hypothesis is beingtested in this experiment?- If camouflage coloration protects mice from predators, then mice that matched their environmentwould be preyed on less then mice with coloration that didn’t match their habitat. Define these terms:- Independent variable- A factor whose value is manipulated or changed during an experiment to reveal
