Put in order from simplest to most complex: Tissues, Cells, Organism, Organ System, Organ. List and describe the 7 characteristics of life. Know the steps of the scientific method. Define an independent variable, dependent variable, control group, and experimental group. You may use examples. What is the difference between a control group and an experimental group? Why do scientists repeat experiments? Give an example of a hypothesis in the “if/then” format that could be tested in the classroom. What is homeostasis? Provide an example of how an organism maintains homeostasis. What are the three domains of life? Define biosphere, ecosystem, population, and community and provide an example of each. Be able to graph and interpret a set of data appropriately. Review types of graphs and criteria to include on a graph. Be able to use a graph to analyze data.
Understand the Problem
The questions cover various fundamental concepts in biology, including the levels of organization, characteristics of life, scientific method, variables in experiments, differences between control and experimental groups, the importance of repeating experiments, formulating hypotheses, the concept of homeostasis, the domains of life, ecological terms, and graph interpretation. These questions aim to test the understanding of core biological principles and experimental design.
Answer
Cells, Tissues, Organ, Organ System, Organism. Seven life characteristics; scientific method; variable definitions; hypothesis; homeostasis; three domains; definitions for biosphere, ecosystem, population, community.
- Order: Cells, Tissues, Organ, Organ System, Organism. 2. Seven characteristics of life: organization, metabolism, homeostasis, growth, reproduction, response to stimuli, and evolution. 3. Scientific method steps: observation, question, hypothesis, experiment, analysis, conclusion. 4. Definitions: Independent variable – the manipulated factor, Dependent variable – the measured factor, Control group – baseline group, Experimental group – group with the independent variable applied. Difference: Control group serves as a benchmark; Experimental group receives the variable being tested. Scientists repeat experiments to ensure reliability and accuracy. 5. Hypothesis Example: If plants receive more sunlight, then they will grow taller. 6. Homeostasis: Maintaining internal balance, e.g., human body temperature regulation. 7. Three domains: Bacteria, Archaea, Eukarya. Definitions: Biosphere – part of Earth supporting life, e.g., worldwide ecosystem, Ecosystem – community and environment, e.g., desert, Population – individuals of a species, e.g., herd of elephants, Community – interacting populations, e.g., ocean creatures. Graph interpretation depends on graph type and criteria.

Understanding these concepts provides a foundational understanding of biology and scientific inquiry.
Tips
A common mistake is confusing the independent and dependent variables. Remember, the independent variable is what you change, and the dependent variable is what you measure.
