Molecules Support Growth Practice Test

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)?

A model of muscle growth after exercise shows small molecules inside the organism. Arrows show small molecules being assembled into larger structures in muscle tissue. Before: fewer larger structures are shown in the muscle. After: more larger structures are shown and the muscle tissue is repaired and grown. The model states: “Rearranged molecules support growth and repair.”

What happens to molecules during this growth and repair, according to the model?
