BIOL 1001 Pearson 1 Practice Questions with Correct Answers All of the following are true of all living organisms EXCEPT that they ✅have a nucleus in their cells A mutation can be the cause for ✅natural selection Suppose that a meteorite crashes into Earth and a sample of it is taken to a local research lab for analysis. Embedded several inches within the rocky structure, a microscopic cluster of dormant, spore -like structures is found. The scientists culture some of this material in a standard microbiological nutrient broth, and they are surprised to find many single -celled "organisms" moving around, growing, and reproducing in the broth. The "organisms" behave the same in both daylight and dark conditions, do not require oxygen, and thrive under a wide range of temperatures and pH levels. They stop moving, growing, and reproducing, however, when fewer nutrients are available in the medium.In this scenario, the "organisms" most closely resemble a(n) ✅heterotrophic species of Archaea A good experiment should include as many variables as possible at the same time ✅false Which of the following is FALSE about scientific theories? ✅They are firmly established and cannot be refuted All of the following are features of the scientific method EXCEPT ✅supernatural causes Which of the following is NOT a characteristic of living things? ✅creating energy Homeostasis is a living organism's ✅ability to maintain constant internal conditions even when environmental conditions change Which of the following can be found in bacteria, but not viruses? ✅a cell membrane Viruses are ✅not alive because they are not made of cells and require a host cell for reproduction Which of the following statements about viruses is FALSE? ✅The widespread use of antibiotics has led to resistant strains of viruses Why is combination drug therapy for HIV/AIDS less likely to lead to resistance than single drug therapy? ✅The likelihood of one virus spontaneously mutating to be resistant to several different drugs at the same time is extremely small Suppose you were in charge of sending an unmanned space probe to a new planet in search of life. The probe would be able to collect and test samples and make observations, but the planet is too far away for the probe to be able to bring samples back to Ear th. The probe is small and would only be able to run a few tests, so you want to pick a test for evidence of life that is broad enough to incorporate all forms of life as we know it. Which one of the following tests would be the best to use in this situati on? ✅a test for the presence of cells that contain DNA A statement describing an expected observation or outcome of a scientific experiment is known as a(n) ________ ✅prediction A plant or other organism that can make its own food is known as a(n) _________ ✅autotroph An animal or other organism that cannot make its own food is known as a(n) _______ ✅heterotroph A(n) ________ consists of all the organisms and their nonliving environment within a given area ✅ecosystem ________ is the process of generating hypotheses from a well -supported generalization such as a scientific theory ✅deductive reasoning Bacteria are _______, or single -celled, organisms. ✅unicellular Most fungi, plants, and animals are many -celled, or _______ ✅multicellular ________ is the study of living things ✅biology A(n) _______ cell lacks a nucleus ✅prokaryotic A(n) _______ cell has a "true" membrane -enclosed nucleus ✅eukaryotic you are a historian writing a book about diseases that affected United States history. Which of the following diseases had the largest impact? ✅smallpox Covid -19 is a truly global pandemic. Which of the following was most like it in distribution around the planet? ✅spanish influenza
