2. (1.5 pt) The picture in Figure A shows a well-streaked plate. In plate A, you can see a dilution of microbial growth in each successive quadrant starting from the first one and isolated colonies in quadrant 4. Compare the picture \( B \) to picture \( A \) and diagnose what went wrong with the experiment in B. Your answer must include (a) the problem, (b) the reason for this problem and (c) how it can be corrected, the next time around. Be precise in your answer. 1. 3. (1 pt) After streaking a plate with a bacterial sample and incubating it, you noticed that nothing grew on the plate after the first quadrant (the first quadrant showed growth). Your friend used the same tube of bacteria and got a perfect quadrant streak. State one mistake that you must have made during this process that could have resulted in lack of bacterial growth on quadrants 2,3 , and \( 4 . \)
