hyposmotic

Explanation:

Body fluids are in contact with cells. Cells are surrounded by a semi-permeable membrane, through which can pass certain solutes. If the concentration inside the cells is different from the body fluids, the water molecules will move from the more concentrated compartment to the less concentrated one. This process is called osmosis.

If the body fluids are more concentrated than cells, the solution is called hypertonic (body fluids are hyperosmic). If the body fluids are less concentrated than the cells, the solution is called hypotonic (body fluids are hyposmotic).

many other transport proteins, often called pumps, move materials against a concentration gradient. active transport drives molecules across a membrane from a region of lower concentration to a region of higher concentration. this process, shown in figure 5.1, uses transport proteins powered by chemi- cal energy.
