Some coral reefs grow larger in water that has the right amount of salt. What kind of characteristic is this? A. behavioral
B. environmental
C. organic
D. individual

organic

Explanation:

Specific levels of salinity can provide preferred cell conditions for the specific types of coral species. This is organic because it involves the genetics of the coral.

water is a polar molecule. a chemical bond is a force of attraction between atoms or ions. bonds form when atoms share or transfer valence electrons. atoms form chemical bonds to achieve a full outer energy level, which is the most stable arrangement of electrons. so, false

explanation:

in h2o molecule, two water molecules are bonded by a hydrogen bond but the bond between two h - o bonds within a water molecule are covalent. the greater the electronegativity difference, the more ionic the bond is. bonds that are partly ionic are called polar covalent bonds. nonpolar covalent bonds, with equal sharing of the bond electrons, arise when the electronegativities of the two atoms are equal.
