To build body structures, multicellular organisms use monomers (e.g., amino acids, glucose) to make polymers (e.…
Item EB057001: Some of the molecules from milk a nursing infant drinks are changed into new molecules that become part of its body structures.
How does a nursing infant use the carbon-based molecules from milk to grow?
- Some of the molecules from milk are changed into new molecules that become part of the baby’s body structures.
- Some of the molecules from milk become part of the baby’s body structures, but these molecules are not changed into new molecules.
- The molecules from milk are all converted to energy for growth, so none of the molecules becomes part of the baby’s body structures.
- 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.
