The ductus arteriousus is a blood vessel that connects the pulmonary artery to the descending aorta. Otherwise known as the ductus Botalli, this structure pumps blood into the fetus' non-functioning lungs from the right ventricle. This blood vessel will close at birth and becomes the ligamentum arteriousum.
Answer:
When I first read this question, all I could think about was the capsized fishing charter called, “the Erik”. The inept captain and crew of this boat caused the death of four passengers while three others remain missing. This disaster occurred back in 2011. I knew two of the passengers. One was recovered in 2013. The other is still listed as missing. However, this question concerns the “best story”. So, I’ll give you the accounts of my own experience. Back in 2013, my group of long-range fishing friends had chartered our annual 8-day trip out of Point Loma, San Diego. We had always chartered the same boat; the Shogun. At our traditional dinner the night before boarding, I remember the most notable topic being discussed was the remnants of Hurricane Ingrid. Ingrid had caused high winds and seas in the area where we wanted to fish.

Bacteria are an example of prokaryotes. Prokaryotic cells do not contain a nucleus or any other membrane-bound organelle.</span>
Answer:
social facilitation
Explanation:
The concept of social facilitation was first proposed by Norman Triplett. After observing a cycling event, in which he noticed that cyclist performed better when they have others around competing with them, rather than cycling alone just against time. This led him to duct an experiment where he gave some children strings to wound fishing reel. He observed that, children wound the fishing reel faster in the presence of other children performing similar task, when compared to when perform such task alone.
This concept discovered by Norman Triplett, best illustrates the concept of social facilitation, which posits that, individuals tend to perform better in the mere presence of others or when they perform a task with others, than when performing the task alone.
