Answer:
D. It is the sharing of electrons between atoms with an electronegativity difference below 1.7
Covalent bonds share electrons, whereas ionic bonds exchange electrons. Covalent bonds have an electronegativity of 0.0-1.7 (0.0-0.3 is a nonpolar covalent bond and 0.3-1.7 is a polar covalent bond). Ionic bonds are bonds that go beyond the electronegativity of 1.7 to 4.0 (1.7-4.0).
I believe it is A because the plant is offering protection while the bacteria is converting it in to nitrogen that the plant can use!
A mineral is a naturally occurring chemical compound,
usually of crystalline form and abiogenic in origin. A mineral has one specific
chemical composition. Coal is not a mineral because it is organic while a
mineral is inorganic that have repeating crystalline structure.
