1) The correct option is e. Neon(10Ne).
Four elements, which make up 96 percent of living matter are oxygen, carbon,hydrogen, and nitrogen.
2) The correct option is e. Water.
During chemical evoltion , elments reacted with each other to
form small inoragnic molecules. Water is a critical solvent for
elements and simple molecules.
3) The correct option is a. The micelle formed spontaneously
because of the properties of the polymer and acted as a barrier to
movement of molecules through the bilayer.
When phospholipids are present in water, the molecules spontaneously arrange such that the tails are protected from the water and results in the formation of membrane structures such as bilayers, vesicles, and micelles.
4) The correct option is e. Dissociate.
When ionic compounds dissolve, the individual ions dissociate and are solvated by the solvent and dispersed during the resulting solution, because the ions are released into solution when dissolved and can conduct charge.
