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.

Answer:
The correct answers are B and C. The tsunami waves were as high as 500 feet, and it was triggered by a 9.1 magnitude earthquake.
Explanation:
The 2004 Indian Ocean tsunami was a series of tsunamis that swept the shores of most countries along the Indian Ocean on December 26, 2004, killing almost 280,000 people. This is considered one of the biggest natural disasters in history. The tsunami was caused by a huge 9.1 magnitude earthquake that shook the underwater off the west coast of Sumatra. This was the third largest earthquake measured by a seismometer. The ensuing tsunamis reached a height of 30 meters in some places when they made landfall. It has been confirmed that 131,028 people have died in Indonesia. More than 30,000 died in Sri Lanka and thousands died in India and Thailand. In Somalia, 4,500 km from the epicenter, 176 people were killed and about 50,000 people lost their homes. $ 14 billion in emergency aid was collected for the worst-affected countries.
