How does a nursing infant use the carbon-based molecules from milk to grow?

1. Some of the molecules from milk are changed into new molecules that become part of the baby’s body structures.
2. Some of the molecules from milk become part of the baby’s body structures, but these molecules are not changed into new molecules.
3. The molecules from milk are all converted to energy for growth, so none of the molecules becomes part of the baby’s body structures.
4. The molecules from milk are all converted to waste materials that leave the body, so none of the molecules becomes part of the baby’s body structures.
