Answer:
Option (C).
Models help scientists visualize things they can'tsee
Explanation:
Since a long time models have been used by scientists to study about various things and phenomenons. A model helps the scientist community understand things that they cannot actually see or fathom. It can be thought of as a thinking tool, to help form explanations. It represents physical and touchable visualization of the theory rather than imaginative.
Models are useful simplifications to aid understanding. It can then be used to explain further phenomena and to make predictions of future behavior. Hence, models are very helpful for scientists in various studies.
Answer:
AI-generated answerScientists use models for several reasons:
1. Models make some things easier to understand: Models are simplified representations of complex phenomena or systems. They help scientists break down complicated concepts into simpler components, making it easier to understand and study.
2. Models help scientists visualize things they can't see: Many scientific phenomena occur at scales that are too small or too large to observe directly. Models allow scientists to visualize these phenomena by creating representations that are more manageable and observable. For example, scientists use models to understand atomic structures or celestial bodies.
3. Scientists can analyze models to make predictions: Models provide a way for scientists to test and analyze various scenarios without directly manipulating the real system. By adjusting variables in the model, scientists can make predictions about how the real system might behave under different conditions. This allows them to gain insights and make informed decisions without the need for costly or time-consuming experiments.
4. Measurements can be made only on models: In certain situations, it may be difficult or impossible to make direct measurements on the real system. In such cases, scientists can create models that replicate the behavior of the system and make measurements on the model instead. This allows them to gather valuable data and draw conclusions about the real system. It is important to note that while models are valuable tools for scientific understanding, they are not always perfectly accurate representations of objects or phenomena. Models are simplified versions of reality, and they may not capture all the complexities or intricacies of the real system. Scientists continuously refine and improve models based on new evidence and observations.
