Models in Science Quiz

Match the following reasons with their explanations for why models are often used in science.

• They are cost-effective alternatives.

• Because the real object is too large, too complicated, or not readily available.

• They represent objects that are impractical to use directly.

• Because they are more accurate than real objects.

• They offer visual appeal and engagement.

• Because they are more colorful.

• They provide a higher level of precision and detail.

• Because they are cheaper than real objects.

What is one advantage of using models when studying multicellular organisms and their body systems?

• It reduces the need to use a dead organism.

• It makes the study more interesting.

• It is easier to understand.

• It is more fun.

Which model is more accurate according to the lesson?

• The 2D computer-generated image of the human digestive system.

• The actual photograph of a pig’s digestive system.

• Both models are equally accurate.

• Neither model is accurate.

What is one benefit of the photograph of the pig’s digestive system mentioned in the text?

• It is more colorful.

• It shows the organs as they really appear inside the body.

• It is easier to create.

• It is less detailed.

What is one advantage of using a photograph to study body systems?

• It shows the entire system in relation to the rest of the body.

• It shows the exact textures of the organs.

• It shows representations of the organs.

• It shows the bones beneath the muscles.

What is one limitation of a 2D image model?

• It does not show the exact textures of the organs.

• It shows the entire system in relation to the rest of the body.

• It is too large or difficult to obtain.

• It is most effective in terms of accuracy.

Why are multiple models used to study the same system?

• To build a complete picture of the system.

• To reduce the cost of research.

• To avoid using real bodies.

• To simplify the study process.

What is the periosteum?

• A layer of connective tissue that surrounds and protects a bone.

• A type of muscle found in the human body.

• A model used to study body systems.

• A photograph of the digestive organs.

Why do medical students use real bodies to study human body systems?

• Because they need familiarity with a real body.

• Because real bodies are easier to obtain.

• Because real bodies are more cost-effective.

• Because real bodies are more accurate than models.
