Biology 101: Module 1 Exam Study Questions with 100% Correct Answers Already Graded A+ 1. Characteristics of living things - ANSWER Cells Energy Reproduction Heredity Responsive to environment 2. Cells - ANSWER All living things are composed of cells Unicellular (bacteria and protists) Multicellular (plants, animals, fungi) 3. Energy - ANSWER All organisms acquire and use energy photosynthesis, biochemical reactions 4. Metabolism - ANSWER energy transfers within cells build & breakdown molecules require enzymes 5. Reproduction - ANSWER organisms reproduce their own kind Asexual & Sexual Hypothesis testing (making predictions and testing them with experimental group and control group) 6. Theory - ANSWER A hypothesis that has been tested with a significant amount of data (Cell theory, Gravity, evolution, etc.) 7. Red-winged blackbird experiment - ANSWER Observation: only males had red patches Hypothesis: red patch involves territory defense Experiment: blacken the red patches on some birds and examine their territory defense abilities 8. Ecology - ANSWER The study of how living things interact with each other and their environment (abiotic and biotic) 9. Abitoic Factors - ANSWER non-living Resources (nutrients and energy) Conditions (temperatures, rainfall etc.) 10. Biotic Factors - ANSWER Living Animals and other organisms 11. Heredity - ANSWER Passing of traits from parents to offspring DNA, Genes, Rules of Inheritance (chances in offspring) Mendel (1860s contributed to this understanding) 12. Response to the environment - ANSWER Sensory receptors -Escape predators -Find food -Move to light -Move away from toxins -Find mates 13. Levels of organization - ANSWER atom, molecule, organelle, cell, tissue, organ, organism, p 14. Characteristics of a species - ANSWER -Habitat: Where a species lives; its "address" -Niche: What a species does for a living; its occupation; Physical environment tolerances Example: buffalo -Habitat: grassland (prairie) -Niche: grazes on grasses; Able to survive in the winter opulation, community, ecosystem, biosphere 15. Photosynthesis - ANSWER Plants use the sun's energy to convert water and carbon dioxide into sugars 16. Underlying themes of Biology - ANSWER Unity within diversity 6 Kingdoms Cells Common genetic code 17. Evolution - ANSWER Change in species over time due to natural selection and other mechanisms 18. Adaptations - ANSWER result of natural selection; traits that improve success in an environment (ex: hummingbirds and flowers they pollinate) 19. Scientific Method - ANSWER Establish casual relationships using logic 20. Components of the Scientific Method - ANSWER Observation Develop hypotheses 21. Levels of organization (ecology) - ANSWER Individuals Populations (groups of the same species in an area) Community (all species in one area) Ecosystems (communities and their interactions with physical environment) Biosphere (life covering Earth)
