Biology 107 Biology, Race, and Racism 26 August 2023 First Quiz due 11:59pm on 11 September 2023 1 point each except 7 and 8 which count 2 points each. 1. Summarize the policy on assignments turned in late in this course. all assignments should be turned in on time,but if you turn them in late by less than 2 weeks it will count on time.if the assignments are turned in more than 2 weeks late they have a 10% deduction. 2. Summarize how the discussions will be graded. There are three criteria that are graded form 4 to 1(excellent 4-needs effort 1) and they are depth of response,quality of evidence and respectful self-awareness. 3. Which of the items below represents the best example of an experimental result? a) If life can arise spontaneously, then sterile broth grown in a sterile flask with a shape that prevents dust from entering will still show cloudiness over time due to bacterial growth. b) Sterile broth is added to two different sterile flasks with s-shaped necks. The neck of the first flask remains intact (the control condition). The neck of the second flask is broken off so that the new opening faces upwards (the experimental condition). c) After 48 hours, the flask for the control condition remains clear. Meanwhile, the flask for the experimental condition is cloudy. Looking at broth samples from each flask under a microscope shows that the cloudiness is due to bacterial growth. d) Life does not arise spontaneously, because only the broth that was exposed to dust actually grew bacteria. 4. Which of the following items is NOT part of the basic logic of a scientific argument or claim? a) A specific prediction or expectation b) An idea about how something in the natural world works in general c) Development of a new measuring tool d) One or more observations 5. Which of the following options represents the best definition of a dependent variable? a) Something in an experiment with the potential to be disproven. b) Something in an experiment that is measured in order to test a hypothesis. c) Something in an experiment that is changed on purpose in order to test a hypothesis. d) A condition in an experiment with "no" or "zero" treatment. 6. Into which part of the Science Flowchart does publishing a peer-reviewed scientific paper fit the best? a) Testing ideas b) Benefits and outcomes c) Exploration and discovery d) Community analysis and feedback 7. Which are features of all well-constructed experiments? Choose all that apply. a) The experiment contains replicates or multiple trials. b) One of the treatment conditions is a placebo. c) As many variables as possible are intentionally kept constant between different treatments, except for the variable(s) that the experimenter wants to test. d) The hypothesis can potentially be disproven. 8. In the video, "How Science Works," Charles Griswold rejected the initial hypothesis that the spider Tracy Odesio collected in a cave was a brown recluse. Name at least two things the research group did next in order work out what sort of spider it actually was? They shared ideas,went to the books,compared the new spider to all the other spider descriptions and they consulted books on fossil spiders. List the people you consulted to compare and improve your answers after first working on them by yourself: Hafsa sakariye
