Students made cakes to model how changing gene structure affects proteins. Student groups were given the same instructions and materials except the milk was substituted for water. Analyze the model and select the statement that best explains how the model represents a change in gene structure.

Multiple Choice

Students made cakes to model how changing gene structure affects proteins. Student groups were given the same instructions and materials except the milk was substituted for water. Analyze the model and select the statement that best explains how the model represents a change in gene structure.

• The model is correct because it uses different materials to try to build the same product.

• The model is incorrect because it uses different materials to try to build different products.

• The model is incorrect because it uses the same materials to try to build two different products.

• The model is incorrect because it uses the same materials to try to build the same product.
