BIOL 101 Guided Reading Questions GRQs Complete and submit this GRQ as a PDF before lecture and before your online Mastering Assignment L1 GRQs Exploring Life and the Process of Science The highlighted modules from the chapter can be used to answer the questions you are not responsible for material that is not part of the answer to a question below Reading objectives 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 Module 1 1 Biology is the scientific study of life 1 What are the characteristics that define all life Hint check the figure a The characteristics that define life are order reproduction growth and development response to the environment regulation energy processing and evolutionary adaptation 2 What is the smallest unit of life a A cell is the smallest unit of life 3 THINK and EXPLORE Most biologists do not think viruses are alive because they reproduce on their own But within a host like you they can replicate and evolve so they are a grey area If you are interested in this do some google searches on are viruses alive and see some of the debate Module 1 3 In life s hierarchy of organization new properties emerge at each level 1 Arrange these words in a correct order community cell organism organ system biosphere molecule tissue organelle population organ ecosystem a Biosphere Ecosystem Community Population Organism Organs and organ systems Tissue Cell Organelle Molecule 2 Consider the individual properties and uses for a bucket a chain or a wheel What happens when you put them together in a system how does a larger function emerge a The bucket chain and wheel work as a pulley system when put together They serve their own purposes on their own but together they serve a larger more complex purpose 1 BIOL 101 Guided Reading Questions GRQs Complete and submit this GRQ as a PDF before lecture and before your online Mastering Assignment Similarly individual tissues can have specific functions but when put together with other tissue types in certain configurations in organs new functions arise This concept is known in biology as 2 words b Emergent properties Module 1 4 What is science 1 Review and define the terms below A Quantitative Data are generally numerical measurements B Qualitative Data are generally in the form of recorded descriptions C A hypothesis is a proposed explanation for a set of observations D A hypothesis leads to a prediction that we can test E An experiment is a scientific test carried out under controlled conditions 2 How do we prove a hypothesis is true To prove a hypothesis you have to run various test to see what solution fits the problem The theory is a broader scope supported by a large and growing body of evidence at hand 3 How is a theory different from a hypothesis 4 How is science different from other ways of describing and explaining nature such as philosophy and religion Fill in the rest of this statement from the text The scientific view of the world is based on hypothesis testing and verifiable evidence 5 What is the main requirement for a scientific hypothesis Note this is the end of module question from 1 4 these are also very useful review quiz like questions during reading and studying It must generate predictions that can be tested by experiments or gathering further observations Module 1 5 Hypotheses can be tested using controlled experiments 1 Review and define the terms below based on the described experiment 2 BIOL 101 Guided Reading Questions GRQs Complete and submit this GRQ as a PDF before lecture and before your online Mastering Assignment A The hypothesis being tested with the two groups of mice is Color patterns have evolved as adaptations to protect the mice from predators B Independent variables are manipulated by the researcher C The dependent variable is used to judge the outcome of the experiment D Control groups differ in only one variable compared to the experimental group 2 As you learned in Module 1 4 predictions are if then statements What was the if then prediction statement made by the scientists about the beach mouse If camouflage coloration protects mice from predators then mice that matched their environment would be preyed on less frequently than mice with coloration that did not match their habitat Noting the independent and the dependent variables describe the control and experimental groups Describe the results and conclusion Control group The plastic models of mice resembling the native mice Experimental group The mice with the non native coloration The independent variable in this experiment was the color of the beach mice and the dependent variable in the experiment was the number of attacks on the mice based on their color Results and conclusion the noncamouflaged models had a much higher percentage of predation attacks in both habitats The data thus support the camouflage hypothesis Coloration that matches the environment protects animals from predation Note orange TRY THIS box on the page It is an active thinking question These make great quiz like review practice questions in your reading and studying Module 1 6 Hypotheses can be tested using observational studies 1 Module 1 6 details how hypotheses can be tested even if a controlled experiment cannot be performed Explain how observational data led to classification of the red panda Red pandas and giant pandas were categorized in the same biological family by some scientists due to their comparable diets and habitats while other scientists categorized the two species in the same family because they had similarities with raccoons Evolutionary relationships were investigated using DNA sequence comparisons during the observational eras Given the available data the DNA sequences analyzed demonstrated that the red panda was the only member of its own family Module 1 7 The process of science is repetitive nonlinear and collaborative 13 The flashlight figure might give you the impression that there is a linear recipe to follow for science In fact most scientific studies are non linear and require repetition and collaboration Draw Figure 1 7 below and explain the components to yourself as we will be 3 BIOL 101 Guided Reading Questions GRQs
