Question

3. The l infectious technique that prevents the contamination of cultures during transfer. Tor F 39. To observe locomotion of Protozoa in pond water, it is essential to make a "smear". Tor F 40. If a prepared smear is dried by heat it is likely to develop cell-shrinkage. Tor F 41. Smears must be thick to ensure that bacteria will be retained on the slide. Tor F 42. The size of bacteria on a NA Petri plate is determined by the availability of nutrients, the incubation temperature and the incubation period. Tor F 43. Macroscopic characterizations of bacterial growth in NB broth tubes included: ecolony shape, colony edge hturbid (cloudy), sediment call the above none of the above 44. When using Pure Culture Techniques. a isolated pure colonies can be obtained by the Streak Plate Method isolated pure colonies can be obtained by the Pour Plate Method call the above none of the above 45. When completing the Streak Plate Method, when do you flame the Inoculating Loop? The loop is flamed before you pick up a loopful of organisms from the NB tube The loop is flamed before you streak quadrants two, three and four call the above are correct none of the above are correct
