Next the researchers repeated the experiment in part c but instead of mixing the ax and ay strains, they put one strain on each

side of a glass u-tube. the u-tube contains a glass filter between the two strains of bacteria that prevents the cells from interacting directly. on which type(s) of media would you expect cells from the ay side of the u-tube to grow?

The correct answer is none of the above.

Bacterial cells can transfer genetic material through a process called bacterial conjugation. This process involves the direct physical contact of the bacterial cells and a horizontal gene transfer. The genes which are transferred are most of the times beneficial for the recipient, such as genes for antibiotic resistance.

In this example, bacterial cells cannot have physical contact, since they are separated by a glass filter. Therefore, the bacterial conjugation cannot happen. Given that no gene transfer can be achieved, the AY strain remains bio- trp- and is unable to grow on any medium that lacks bio or/and trp.

Which of the drugs (if either) was more successful in preventing the recurrence of depression relative to the placebo?
Alex17521 [72]
The results clearly reveal that Imipramine is by far more effective than Lithium in preventing the recurrence of depression. 62.16% of the patients taking Lithium had a recurrence of depression which is more than twice that of patients who took Imipramine (28.95%). 

The results also question the effectiveness of Lithium in general since the percentage of patients who had a recurrence of depression in the Placebo group (67.65%) is only slightly higher than that of the Lithium group (62.16%).

Something that makes reactions start more easily and increase how fast the reaction occurs

That would be catalysts.

Catalysts accelerate (speed up) chemical reactions without damaging itself. They do this by decreasing the activation energy of a chemical reaction.

Enzymes are a type of catalysts.

Answer:

As Jane exercises her heart rate and breathing rate increase because he muscles are asking for more oxygen and get rid of more carbon dioxide. More blood is diverted towards the muscles as they need more oxygen for respiration. She needs to burn glucose with oxygen and water to produce energy so she can run. The way she can get this oxygen into her body is through her lungs. Where oxygen from the air diffuses into the blood and carbon dioxide diffuses out.
