5 Multiple choice questions

  1. A solution in which the concentration of solutes is greater than that of the cell that resides in the solution.,causes a cell to shrink because of osmosis
  2. a gradient in concentration of a solute that molecules move down and the greater the difference in concentration between the two areas, the faster diffusion occurs. It is An increase or decrease in the density of a chemical substance in an area., A difference in concentration between two areas.

  2. endocytosisCell's division (PMAT) of the nucleus. Final product is 2 daughter cells that are exactly like the parent cell., asexual reproduction and contains same number of chromosomes.


  3. desmosomeAnchoring junctions that prevents cells subjected to mechanical stress from being pulled apart; two adjacent cells are attached. formed from protein plaques in the the cell membranes linked by protein filaments


  4. Cell Theory(biology) the basic structural and functional unit of all organisms


  5. ribonucleic acid(RNA)nucleic acid found in all living cells: carries the organism's hereditary information.
