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.
In the start of the light cycle, light-dependent reactions harness energy from the sun in order to create chemical bonds. These bonds are known as ATP and NADPH. These are the molecules that carry energy which are made in the stroma. The stroma is where the Calvin cycle takes place.
Living would not be possible because without the greenhouse effect the earth would be a solid rock or ice.
