| What properties do all living organisms share? | -order -regulation -growth and development -energy processing -response to environment -reproduction |
| List the levels of life. Which level is the smallest. Which level is the largest? | -molecules and atoms -organelles -cells - tissues - organ systems and organs -organisms -populations -communities -ecosystems -biosphere |
| _______ is the branch of biology that deals with relations of organisms to one another and to their physical surroundings. | Ecology |
| An _______ consists of all living organisms in a particular area and all the non-living components of the environment with which life interacts, such as soil, water and light. | ecosystem |
| _______ _______ is the process in which organisms with certain inherited characteristics are more likely to survive and reproduce than are organisms with other characteristics. | Natural selection |
| _______ cells are larger, more complex, and contain a nucleus and other membrane enclosed compartments. | Eukaryotic |
| _______ cells are smaller, more simple, and lack a nucleus with other compartments bound by internal membranes. | Prokaryotic |
| What two processes does an ecosystem depend on for survival? | Nutrients and energy |
| _______ _______ is the process in which organisms with certain inherited characteristics are more likely to survive and reproduce than are organisms with other characteristics. | Natural selection |
| _______ _______ is the selective breeding of domesticated plants and animals to promote the occurrence of desirable traits in the offspring. | Artificial selection |
| _______ is an approach to understanding the natural world that is based on inquiry - a search for information, explanations and answers to specific questions. | Science |
| Scientific investigation involving the observation of phenomena, the formulation of a hypothesis, concerning the phenomena, experimentation to demonstrate the truth of falseness of the hypothesis, and results that validate or modify the hypothesis? | Scientific method |
| What are the components of the scientific method? | observation - question - hypothesis - - prediction - experiment |
| What is the difference between a control group and an experimental group? | - A control group is another group within experiment, not tested, to measure how other tested subjects do. - An experimental group is group within experiment that receives variable being tested. |
| Why is it important to have a control group in an experiment? | Because it allows you to eliminate and isolate the variables. |
| _______ _______ is the process of scientific inquiry that focuses on using observations to describe nature. | Discovery science |
| _______ - driven science is the search for a tentative explanation that a scientist proposes for a specific phenomenon that has been observed. | Hypothesis |
| Which of the following is not a characteristic of all living organisms? a. capable of self-reproduction b. composed of multiple cells c. complex yet organized d. uses energy | b. composed of multiple cells (some living organisms are single-celled) |
| Place the following levels of biological organization in order from smallest to largest: -atom -biosphere -cell -ecosystem -molecule -organ -organism -population -tissue | -atom -molecule -cell -tissue -organ -organism -population -ecosystem -biosphere |
| What is the smallest level of biological organization capable of demonstrating all of the characteristics of life? | The cell |
| Plants use the process of _______ to convert the energy in sunlight to _______ energy in the form of sugar. | -photosynthesis -chemical |
| During the process of photosynthesis plants consume _______ _______ and _______ and release _______. | -carbon dioxide -water -oxygen |
| A foot-tall organism capable of producing it's own food from sunlight would most likely be a part of what domain and/or kingdom? | Eukarya/Plantae |
| A microscopic, simple, nucleus-free organism found living in a riverbed would most likely be a part of what domain and/or kingdom? | Bacteria |
| An inch-tall organism growing on the forest floor that consumes material from dead leaves would most likely be a part of what domain and/or kingdom? | Eukarya/Fungi |
| A thimble-sized organism that feeds on algae growing in a pond would most likely be a part of what domain and/or kingdom? | Eukarya/Animalia |
| Which of the following statements best describes the logic of the scientific method? a. If I generate a testable hypothesis, tests and observations will support it. b. If my prediction is correct, it will lead to a testable hypothesis. c. If my observations are accurate, they will support my hypothesis. d. If my hypothesis is correct, I can expect certain test results. | d. If my hypothesis is correct, I can expect certain test results. |
| Which of the following statements best distinguishes hypotheses from theories in science? a. Theories are hypotheses that have been proved. b. Hypotheses are tentative guesses; theories are correct answers to questions about nature. c. Hypotheses usually are narrow in scope; theories have broad explanatory power. d. Hypotheses and theories mean essentially the same thing in science. | c. Hypotheses usually are narrow in scope; theories have broad explanatory power. |
