Theory - correct answer A hypothesis that has been tested with a significant amount of data hypothesis - correct answer A suggested explanation of an event or a phenomenon which can be tested and proven later can not change or vary throughout experiment can not be accepted or rejected based solely on research data, without conducting any valid experiments and their results. research - correct answer Combining data from past experiments and using it to investigate a particular topic in consideration experimentation - correct answer Using tools and technology to obtain data for comparison and further investigation evaluation - correct answer Analyzing data and its validity scientific process steps - correct answer 1.Observation is the first step of the scientific method. It entails noticing and describing minute details about a certain event or phenomenon. 2.Hypothesis is the second step. It is a proposed scientific statement that can be tested and proven scientifically through experimentation and results. 3.Experimentation is the third step. It involves testing a hypothesis through various experiments. 4.Evaluation is the fourth step. It involves a critical analysis of the recorded results and findings of the experiment. 5.Conclusion is the last step of the scientific process. It explains the findings of the experiments and concludes whether or not the results support the hypothesis. iterative process - correct answer An iterative process is an interactive session for the researcher to reflect on the results of the experiment and take valuable inputs and feedback deductive reasoning - correct answer general to specific reasoning in which a conclusion is reached by stating a general principle and then applying that principle to a specific case (The sun rises every morning; therefore, the sun will rise on Tuesday morning.) this is used by scientists to understand the hypothesis inductive reasoning - correct answer specific to general sun rose on Tuesday so it probably rises every morning non-experimental hypothesis testing - correct answer Non-experimental hypothesis testing is used when a hypothesis cannot be tested in a laboratory set-up due to ethical and practical reasons. conclusion - correct answer The current experimental data and the results are compared with the predicted results of the hypothesis to reach a conclusion. what is considered the heart of science - correct answer experimentation characteristics of living things - correct answer Made Up of Cells Ability to Reproduce Have a Metabolism Maintain Homeostasis Respond to Stimuli Grow and Develop Adapt Through Evolution cells - correct answer cells are small, structural, and functional units of life what is true for all living things - correct answer all livings things can reproduce classification from most to least inclusive - correct answer Domain Kingdom Phylum Class Order Family Genus Species least inclusive level - correct answer species
