While the four disks were soaking in their particular solutions, shestreaked a sterile nutrient agar dish with a society of E. coli bacteria. Then, she placed each disk carefully ontothe nutrient agar dish, placed the lid on the dish, tape-recorded it shut, and incubated the dish at 37°C for numerous days.Figure 19-4 reflects just how the nutrient agar dish looked on Day 1 and also Day 4.Figure 19-446. Designing Experiments Based on Figure 19-4, what is the student more than likely trying to test?a. the solution that each disk is soaked inb. the kind of Petri dishesc. the performance of different disinfectantsd. not sufficient information47. Controlling Variables What is the control in the experiment presented in Figure 19-4?a. The disk soaked in disinfectant 1 is the control.b. The disk soaked in disinfectant 2 is the control.c. The disk soaked in disinfectant 3 is the regulate.d. The disk soaked in distilled water is the regulate.48. Drawing Conclusions How deserve to the student meacertain the effectiveness of each disinfectant presented inFigure 19-4?a. Smell the contents of the Petri dish. If tright here is no smell, the disinfectant worked to kill the bacteria.b. The student have the right to measure the width of the area approximately each disk where bacteria have actually not grown torecognize the performance of the solution in which each disk was soaked.c. Meacertain the amount of water vapor developed. The dish that has actually even more water vapor has actually even more bacteria so thedisinfectant did not work-related to kill the bacteria.d. not sufficient information49. Inferring Look at the dishes in Figure 19-4. Which disinfectant was the a lot of effective at managing thedevelopment of E. coli?a. Disinfectant 1b. Disinfectant 2c. Disinfectant 3d. distilled water50. Drawing Conclusions Look at the results of the experiment presented in Figure 19-4. Why do you think thedifferent disinfectants are not equally effective against the E. coli bacteria?a. Disinfectants act differently to combat bacterial growth.b. Some disinfectants are more effective at controlling one species of bacteria than an additional.c. Bacteria differ considerably from species to species.d. all of the aboveUSING SCIENCE SKILLSComposting is the process of breaking dvery own organic materials under regulated problems. A student set up3 different comshort article bins making use of the setup presented in Figure 19-5. Into each comwrite-up bin, he included anidentical combicountry of timber shavings, shredded paper, nitrogen, and bacteria. He combined the materials ineach bin and also readjusted the insulation roughly the bins to maintain the day-to-day taracquire temperatures. He thenmonitored the temperature, moisture, and also amount of decomposition of the comwrite-up in each bin over an eightweek period. A few of his information are shown in the graph.Figure 19-551. Designing Experiments Based on Figure 19-5, what is the student probably trying to test?a. kind of timber chipsb. the effect of temperaturec. the form of gas producedd. not enough information52. Controlling Variables According to Figure 19-5, which compost bin is the control?a. Compost bin Abdominal. Compost bin Bc. Compost bin Cd. cannot tell53. Inferring Look at the graph in Figure 19-5. How execute you account for the 50ºC temperature in comshort article bin A?a. The 50°C temperature in bin A is created by the bacteria and also other decomposers in the comarticle.b. The 50°C temperature in bin A is generated by the kind of lumber chips offered.c. The 50°C temperature in bin A is created by the type of air being pumped in by the aerator.c. not sufficient information54. Drawing Conclusions At the finish of eight weeks, the student uncovered that the products in which bin hadundergone the the majority of decomposition?a. Bin Abdominal muscle. Bin Bc. Bin Cd. all decomposed at the exact same rate55. Predicting According to Figure 19-5, suppose a fourth comarticle bin were added to the experiment. This binwas retained over 80°C. Predict exactly how the decomposition in this bin would compare via that in bins A, B, and C.a. The organic materials will certainly decreate even even more conveniently than those in bin A.b. However before, it is even more most likely that these products will certainly break dvery own exceptionally little, if at all, because hightemperatures kill bacteria.c. both (a) and also (b)d. namong the aboveUSING SCIENCE SKILLSFigure 19-656. Interpreting Graphics What does Figure 19-6 represent?a. the fermentation of wineb. infection cycles of a lysogenic virusc. the making of cheesed. namong the above57. Comparing and also Contrasting Look at both cycles displayed in Figure 19-6. During which cycle is the hold celldestroyed?a. lytic cycleb. lysogenic cyclec. bothd. neither58. Interpreting Graphics Each phase of the cycles shown in Figure 19-6 is labeled with a letter. Which lettersuggests the phase at which the bacteriophage’s DNA becomes a component of the hold cell’s DNA?a. Stage Abdominal. Stage Bc. Stage Cd. Stage D59.
