<span>The component that nitrogen-fixing bacteria provide and that plants can absorb is soluble nitrates. Since plants cannot directly use nitrogen gas, it must be converted into its soluble form. Plants cannot do this either, but nitrogen-fixing bacteria can. These bacteria convert nitrogen gas into soluble nitrates, such as ammonium, which plants can absorb.</span>
Answer:
B. The hydrogen and oxygen atoms in water share their electrons; sodium transfers an electron to chlorine in sodium chloride.
Explanation:
The bonds between sodium and chloride in NaCl (table salt), and oxygen and hydrogen in water are different as sodium and chloride in NaCl have ionic bond and oxygen and hydrogen in water have the covalent bond.
Sodium transfers an electron to chlorine in sodium chloride (NaCl), so that they both have full outer shell and form ionic bonds. sodium and chloride ions exerts electrostatic force on each other and bond together with ionic bonds.
The hydrogen and oxygen atoms in water have covalent bonds because they are bonded by sharing electrons. Both hydrogen and oxygen atoms share unequal electrons with each other and form V-shaped water molecule.
Hence, the correct answer is "B."
