Final answer:
In biology, models are used to test hypotheses and analyze data. They represent biological processes or systems and are used alongside theories and hypotheses. Examples include the cell theory and the fluid mosaic model for cell membranes.
Step-by-step explanation:
In biology, models are related to theories and hypotheses in that they are used to test hypotheses and help scientists analyze data. A model is a representation or simulation of a biological process or system, while a theory is a well-substantiated explanation of a natural phenomenon based on evidence and observations. Hypotheses are proposed explanations for specific phenomena that can be tested using models and other scientific methods.
For example, in biology, the cell theory is a widely accepted theory that explains the structure and function of cells. Scientists have developed models, such as the fluid mosaic model, to further understand the organization of molecules in cell membranes. These models have been used to test hypotheses about membrane permeability.
