Answer:
D. A positive charge, because of a covalent bond with oxygen
Explanation:
A water molecule contain both hydrogen and oxygen atom. Water is a polar molecule because it has positive electric charge in one of it's poles and negative charge on the other. The hydrogen is positively charged and the oxygen is negatively charged which are bonded by covalent bond. Hydrogen is positively charged because it cannot attract electrons strongly like oxygen which is positively charged. There is unequal sharing of electrons in water molecules and this is why oxygen is slightly negative and hydrogen is slightly positive.
It probably needs to dig in the ground for worms and grub. So it's an adaptation for finding food.
They are the same thing, but there's also carbon dioxide in the ocean, dissolved as carbonic acid. Carbon dioxide literally means one carbon, two oxygens. CO2.
