The cytoplasm of human cheek cells is 96% water and 4% NaCl (salt.) A scientist removes some of your cheek cells and places them
in an solution that is 30% NaCl. Which direction of net water flow would result? a. net water flow out of the cell b. net water flow into the cell c. no net flow; the cell is in equilibrium
The water will flow from a region of high concentration to a region of low concentration.
The cheek cell has 96% water while the medium in which it is placed has only 70% of water (as it has 30% of NaCl). Therefore the water will flow out from the cell into the medium where it is placed.
The functions of nucleic acids have to do with the storage and expression of genetic information. Deoxyribonucleic acid (DNA) encodes the information the cell needs to make proteins.
