Cell A has a surface area of 60um2 and a volume of 15um2. Cell B has a surface area of 36um2 and a volume of 12um2. Using that information, determine the surface-area-to-volume ration of each cell. What is the SA:V ratio of the cell that will exchange materials with is environment at the fastest rate of diffusion?

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.
