Electric potential across a cell membrane in a typical living cell, the electric potential inside the cell is 7.2×10−2 v lower than the electric potential outside the cell. the thickness of the cell membrane is 0.11 μm . you may want to review (pages 696 - 700) . part a what is the direction of the electric field within the cell membrane? what is the direction of the electric field within the cell membrane? outward across the cell membrane inward across the cell membrane tangentially to the cell membrane

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.

chert is a sedimentary rock composed of microcrystalline or cryptocrystalline silica. with this little bit of information, you can come to the conclusion that your answer is c.  

explanation:
