BIOL 2100 Exam 1 official study set (100% correct)

Which of the following statements is true regarding evolution? correct answer Evoltution is the process of change over time that has resulted in the array of organisms found on Earth An organisms adaptations to its environment are the result of evolution. Adaptations evolve over many generations by the reproducive success of those individuals with heritable traits that are best suited to their environments. An organism cannot evolve; the process requires multiple generations. Which of the following is not an accurate statement about biology? correct answer Biological inquiry is a cataloguing of all the processes and properties of life on Earth. Biological inquiry is a way of asking questions that make use of the scientific process, not a simple listing of processes and properties of life. When questions occur to you as you observe the natural world, you are thinking like a biologist Which of the following is not a property associated with all living organisms? correct answer - energy processing - disorder - evolutionary adaptation - regulation Answer: disorder The phenomenon we call life defies a simple, one-sentence definition. Highly ordered (rather than disordered) structure characterized life. Regulation, energy processing, evolutionary adaptation, growth and development, and reproduction are additional examples of what can be observed in all living organisms What is the correct order for the hierarchy of biological organization from the least to the most complex? correct answer molecule, organelle, cell, tissue, organ, organ system, organism, population, community, ecosystem Each level of biological structure builds on the level before it No amino acid molecule by itself can speed up or catalyze reactions between other molecules; however, when amino acids are joined together to make a protein with catalytic properties, the new structure (enzymatic protein) can speed up the rate of a specific chemical reaction. What does this illustrate? Concept 1.1 correct answer Emergent properties A molecule such as a protein has attributes not exhibited by any of its component parts (e.g., amino acids). Therefore, novel properties are emerging that were not present at a simpler level of organization
