If two cultures of a facultative anaerobe were grown under identical conditions except that one was exposed to oxygen and the other was completely deprived of oxygen. Which of the two cultures will contain more cells at the end of a week? Why?
For microbiology
Homework Answers
facultative anaerobe can grow in the presence or absence of oxygen in the presence of oxygen the bacteria carry out aerobic respiration and produce 36 ATP from a single glucose molecule, but in the absence of oxygen, the facultative anaerobe carries out fermentation and produces 2 ATPs from a glucose molecule.
the large amount of ATP is produced in the presence of oxygen, so the bacteria can grow more rapidly in the presence of oxygen, compared to the culture that grows in the absence of oxygen so the culture growing in the presence of oxygen will have more bacteria at the end of the week because in the presence of oxygen the glucose is used more efficiently.

The protein-synthesizing machinery was isolated from
eukaryotic cells and briefly treated with a low concentration of
RNase. The sample was then subjected to sucrose gradient
centrifugation. The gradient was fractionated and the absorbance,
or optical density (OD), at 254 nm was recorded for each fraction.
The following plot (graph A) was obtained.
a) what do the three peaks of absorbance in graph A represent?
Label each one.
b) The experiment was repeated except that, this time, the
RNase treatment was...

Two conductive spheres are identical in every way except that one is twice as big as the other. Both are equally negatively charged. The two spheres are brought together and allowed to touch. Which of the following statements is true? There will be no movement of charge at all The electrons will spread out as much as possible meaning that the larger sphere will have more electrons than the smaller. The negative charge will spread out equally between the spheres...

Two pots are identical except that the flat bottom of one is aluminum, whereas that of the other is copper. Water in these pots is boiling away at 100.0 °C at the same rate. The temperature of the heating element on which the aluminum bottom is sitting is 177 °C. Assume that heat enters the water only through the bottoms of the pots and find the temperature of the heating element on which the copper bottom rests. Tau=

Two pots are identical except that the flat bottom of one is aluminum, whereas that of the other is copper. Water in these pots is boiling away at 100.0 ˚C at the same rate. The temperature of the heating element on which the aluminum bottom is sitting is 153 ˚C. Assume that heat enters the water only through the bottoms of the pots and find the temperature of the heating element on which the copper bottom rests.
