What does glycine betaine do to protect photosystem II activity? Choose all the correct answers.

-as betaine levels increase, association of proteins also increase

-as betaine levels increase, association of proteins decrease

-betaine helps keep proteins associated and photosynthesis functioning

-betaine denatures proteins causing disassociation

really dont know just need some points

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.
