When you jump in the bath, water does not run around all your cells and directly into your body. Instead water intake and release is regulated by special proteins called aquaporins. Why can't water run around your cells but instead has this regulation? Select one: a. Water is nonpolar, like our bodies and so cannot mix easily. b. Because we live in a hypertonic environment anyway. c. Desomosomes and gap junctions provide orientation for water movement. d. Our epithelial (skin) cells have tight junctions which form a 'water-tight' seal between cells preventing substances from going around the cell.
