Bread dough made from wheat flour will leaven (rise) when left at room temperature for 30 min because: a. pathogenic bacteria like E. coli O157:H7 double in population density every 30 minutes at room temperature b. it contains sodium acetate which lowers the pH to 4.5 c. yeast added to the dough consume sucrose (table sugar) and produce ethanol + CO2 (carbon dioxide gas) during this 30 min period at room temperature d. egg white albumen protein was painted onto the surface prior to baking e. gluten in the dough traps gases that are produced during the fermentation that occurs during this 30 min period at room temperature
In the sediments at the bottoms of ponds and lakes, there is often absolutely no O2 at depths of 0.5 cm or more, even if the water above is rich in O2. How is this possible? (Do not put answer from chegg thanks).
Write an abstract of the article below in Results (around 3-4 sentences): RESULTS AND DISCUSSION For the duplicate sets of reactors in experiments A and B, reactors inoculated with Pond 1 started gas formationsooner and peaked earlier than the Pond 2 and Horse Dung reactors. For both sets of reactors, the reactor seeded with pond bottom soil obtained from Pond 1 had the highest methane generation rate, as well as the largest cumulative volume of methane, followed by Pond 2 and finally the reactor seeded with Horse Dung, as shown in Figure 1(A) and (b) below. The possible reason is that Pond 1 is an older pond compared to Pond 2, and the bottom soil obtained from the Pond 1 may have more stable organic matter accumulated as well as higher nutrient concentrations, leading…

The water in theYellowstone NationalPark hot springs shownhere is around 160°F(70°C). Biologistsassumed that no speciesof organisms couldlive in water aboveabout 130°F (55°C), sothey were surprisedto find several speciesof bacteria there, nowcalled thermophiles(“heat-lovers”). You’ve learned in this chapter how an enzymefrom one species, Thermus aquaticus, made feasible one of themost important DNA-based techniques used in labs today.Identify the enzyme, and indicate the value of its being isolatedfrom a thermophile. Suggest other reasons why enzymes fromthis bacterium (or other thermophiles) might also be valuable
Erwin Chargaff did not have any DNA samples from thermoacidophilic bacteria such as those that thrive in the geothermal (hot) springs of Yellowstone Park. Such bacteria had not been isolated in 1951 when Chargaff reported his results. If he had obtained such a sample, what do you think its relative G-C content might have been? Why?
