Molecules Support Growth Practice Test

A simplified model shows a caterpillar growing after eating. Before: small molecules are shown inside the caterpillar. The model shows these small molecules being rearranged and connected into larger structures in the body. After: the caterpillar has more body tissue, and the larger structures are now part of the new tissue. The model includes the statement: “Rearranged molecules support growth and repair.”

Which set of statements is supported by the model? (Choose the best option.)

A model of a growing puppy shows many small molecules inside the puppy. Arrows show small molecules being connected into larger structures in muscles and bones. Before: fewer larger structures are shown. After: more larger structures are shown as part of new tissue. The model includes the sentence: “Rearranged molecules support growth and repair.”

Which prediction is supported by the model if the puppy does not get enough small molecules from its surroundings (for example, not enough food/water molecules entering the body)?
