Experimental models refer to scientific tools or systems used to study a particular phenomenon or process in a controlled and reproducible way. These models can range from simple organisms like bacteria or yeast to more complex systems such as animal models or cell cultures. Experimental models are crucial in scientific research as they allow researchers to manipulate variables, test hypotheses, and gain insights into biological processes or disease mechanisms. They provide a platform for studying the effects of interventions, such as drugs or gene editing, and can help researchers understand the underlying mechanisms of a particular phenomenon. Overall, experimental models play a key role in advancing scientific knowledge and are essential for making discoveries that can ultimately lead to improvements in human health and well-being.
