WebWater’s lower density in its solid form is due to the way hydrogen bonds are oriented as it freezes. Specifically, in ice, the water molecules are pushed farther apart than they are in liquid water. That means water expands when it freezes.

WebActive transport systems move chemicals essential to cellular functions through the membrane into the cell. Such essential chemicals include calcium ions, amino acids, carbohydrates, and vitamins. Because the structures of poisons usually are not similar to those of chemicals essential to cells, few poisons are absorbed by active transport.
