Answer:
C. Gas exchange occurs through the placenta.
Explanation:
The fetus is a developing baby in the womb or uterus. The fetus is incapable of performing certain life processes itself and hence, depends on the mother to do them. One of these processes is GAS EXCHANGE. Gas exchange occurs in the fetus via a structure called PLACENTA.
Placenta is a structure that forms in the uterus during pregnancy. It helps the developing fetus supply oxygen and nutrients from the mother and also remove wastes from the fetus back to the mother. The oxygen is taken into the fetus via the PLACENTA while the carbon dioxide (waste product of respiration) is removed via the PLACENTA. Hence, Gas exchange occurs through the placenta.

Explanation:
Because the atoms in metals form a matrix through which outside electrons may easily travel, metals are good conductors of electricity and heat. They generate a sea of electrons around the positive nuclei of the interacting metal ions, rather than circling their particular atoms.
The free flow of shared electrons can carry an electric current through a metal. Carbon atoms join with iron atoms to create bonds.
