  1. Welcome to BTN The Biological Trivia Network

  2. How to play • Each team needs 5 large (8.5 x 11) sheets to indicate their choice: • One each marked A, B, C, D, and E • For each question, raise the sheet corresponding to the choice you believe is correct • You may change you answer at any time • The point value decreases with time • The teacher will award points to each group based on when the correct answer was raised

  15. Which of the following is not part of the modern cell theory: A The cell is the basic unit of structure Surface area to volume ratio is a very limiting factor in size because material can only enter the cell through the limited area of its cell membrane B All cells came from pre-existing cells 1000 C Organisms are composed of cells 250 D Unlimited size E The function of the whole organism is dependant on the function of its cells 500 750

  17. Which three organelles are present in plants but not animals: A Cell wall, Large Central vacuole, chloroplast The chloroplast is for photosynthesis, the vacuole is to generate turgor pressure, and the wall helps hold that pressure.

  19. The process of water moving across a selectively permeable membrane is 250 A Active Transport Osmosis is a specific case of diffusion. Both are types of passive transport. 1000 B Passive Transport C Hydrolysis D Osmosis 500 E Diffusion 750

  20. Which of the following is located in the central portion of the lipid bilayer: 250 A The non polar portion of the molecule The hydrophilic water loving phosphate heads make up the outside layer, the portion in contact with the liquid environment. The hydrophobic lipid tails face each other to get away from the liquid environment. B The phosphate portion C The polar portion of the molecule D The polar tail 1000 E The hydrophobic head 500 750

  21. Dynamic Equilibrium implies 500 A Balance with particles not moving Diffusion and Osmosis occur because of a difference in concentration in two different areas and the fact that particles are always moving. Equilibrium is achieved when the concentrations become equal, but the particles still always move 2000 B Imbalance with particles moving C A changing concentration gradient D A stable sloping slide E Balance but with particles moving 1500 1000

  22.

  23. The process demonstrated here is 1000 3000 Slow Diffusion A B Endocytosis C Exocytosis This is active transport because the cell uses energy to move the molecules.

  30. This reproductive cycle is 750 The lysogenic cycle has a ‘dormant’ phase during which the viral genetic material incorporates into the cells chromosomes.
