BIO 101 ALL QUIZZES Introduction to Biology Quiz 01/08/2016 6:51 AM EST 01/08/2016 7:15 AM EST 70% 70 out of 100 Question 1 10 out of 10 A cleaning product claims it “kills 99.9% of germs and viruses.” Explain the flaw in this statement. This claim has many flaws. It depends on the amount of bacteria, the area covered, and amount of cleaner used. The biggest flaw is most cleaners don't kill all types of bacteria. This is a marketing ploy that compares cleaning products. Feedback This statement is technically inaccurate since viruses cannot be killed; a virus is abiotic. A virus does not meet ALL of the four requirements outlined above to be considered a biotic organism. Question 2 10 out of 10 Which of the following would a biologist study? Select all that apply. 1. How bacteria respond to antibiotic treatments. 2. How algae interact with various fish. 3. How to produce new varieties of corn plants. 4. How earthquakes can be better predicted. Feedback Correct. Bacteria, algae and fish, and corn are living organisms studied by biologists. Question 3 10 out of 10 This level of organization is the defining level of biology. As far as we know, life is an emergent property that exists at this level. Below this level, no single entity is truly alive. 1. organism 2. cell 3. molecule 4. population Feedback Correct! A cell, given the right conditions, can perform all of the activities of life. Question 4 10 out of 10 Read the following statements. Which one is NOT an example of the characteristics of life? 1. Your body gives off heat after running up several flights of stairs. 2. Drinking water after perspiring while working in the garden on a hot day. 3. A single-celled organism dividing into two separate organisms. 4. A fertilized egg developing into a young chick. 5. All of the examples above demonstrate characteristics of life. 6. None of the examples above demonstrate characteristics of life. Feedback That's correct. All of these examples demonstrate characteristics of life. Question 5 10 out of 10 On the surface of the eye is a transparent, flexible covering called the cornea. This structure would best be classified as a... 1. organ system 2. organ 3. organelle 4. tissue 5. cell Feedback Correct, the cornea might be classified as a tissue, but it contains specialized layers of cells, so it is probably better considered a collection of tissues. Question 6 0 out of 10 Aristotle’s statement “The whole is much greater than the sum of its parts.” Explains which of the following? 1. Interactions between biotic and abiotic components 2. Emergent Properties 3. Life uses energy and raw materials to grow 4. None of these Feedback Incorrect. Interactions are not emergent. Question 7 0 out of 10
