5 Matching questions

  1. osmosis
  2. anaphase
  3. concentration gradient
  4. protein synthesis
  5. hypotonic solution
  1. a 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. b Forming proteins based on information in DNA and carried out by RNA
  3. c Diffusion of water through a selectively permeable membrane
  4. d A solution in which the concentration of solutes is less than that of the cell that resides in the solution, causes a cell to swell because of osmosis.
  5. e 3rd phase; the chromatids of each chromosome separate at the centromere and move in opposite poles of the spindle.

5 Multiple choice questions

  1. Energy-requiring process that moves material across a cell membrane against a concentration difference or gradient
  2. Communicating Junctions; channels that allow small molecules to flow through protein-lined pores between cells. common in the heart and embryonic cells.
  3. Cells are tightly bound, prevent fluids and most molecules from moving between cells. Useful in places such as the stomach and kidneys. types are desmosomes, tight junctions, and gap junctions
  4. Process by which a cell divides into two new daughter cells
  5. Cell'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.

5 True/False questions

  1. Cellbiological unit of hereditary information located in chromatin consisting of a specific nucleotide sequence in DNA (or RNA, in some viruses). that transmits hereditary information.

  3. enzymeA substance produced by a living organism that acts as a catalyst to bring about a specific chemical reaction

          

  4. OrganelleA tiny cell structure that carries out a specific function within the cell

          

  5. desmosomeA threadlike, gene-carrying structure found in the nucleus. consists of one very long DNA molecule and associated proteins.
