TEST 1: BIO 111-02 - Steimle Note the following: There are 40 questions with a total of 40 points possible for the exam. You have 60 minutes to complete the exam (in one sitting). Extended time will be given to those with approved accommodations. You must take the exam entirely at the UPL. Failure to do so will be considered an academic integrity violation. You will be provided scratch paper if you want it. The paper will be collected before you leave the UPL. No devices, phones, notes, websites, or any other additional materials may be used during the exam. Remember to: Stay calm. You have plenty of time to complete the exam. Read each question and the answer choices closely and more than once. Go over your answers at least one more time after you have answered all of the questions. 1 1 point Which one of the statements explains a characteristic of both all living organisms and all nonliving material?

Clear my selection 16 1 point The lowest (simplest) level of biological organization that can exhibit all of the properties assocated with living things is a (an) Cell Molecule Atom Tissue All of the above, depending on the organism. Clear my selection 17 1 point After observing that squirrels live in areas with trees but not open fields, a scientist makes the statement that “squirrels need trees to live”. This statement is an example of a hypothesis fact. prediction. research question. Clear my selection 18 1 point A pet store owner was having trouble keeping new shipments of fish healthy after their arrival at the store. She thought that if she increased the amount of oxygen in the tank water, then the survival rate of the fish will improve. The owner then tested this on the next shipment of fish by placing half of the new fish in the normal tanks, and the other half in tanks with more oxygen added. She monitored the general health and survival of the fish over a one-week period under the two sets of conditions. Which of the choices below represents the control group in this experment. oxygen levels of the water. the new fish in the tanks in with more oxygen was added. the new fish in the tanks without more oxygen added. the survival rate of the fish. Clear my selection 19 1 point Provide the correct order of steps in the scientific process. First Step Experiment Prediction Observation Hypothesis Question Last Step 20 1 point Some bacteria release chemicals that inhibit the growth of fungi. To test if this is true, a scientist grows fungi in two cultures, one without bacteria and one with bacteria. The scientist then collects data on the number of fungal cells in each culture. In this experiment, __________ is the independent variable, __________ is the dependent variable, and __________ is the control. the presence of bacteria/the absence of bacterial cells/the number of fungal cells the presence or absence of fungal cells/the presence or absence of bacteria/the fungal culture containing bacteria the presence or absence of bacteria/number of fungal cells/the fungal culture without bacteria There is not enough information to answer this question.
