Answer: Raymond Wang: How germs travel on planes – and how we can stop them
1. After completing the unit and watching the video, explain how the unit about oceans and the video about germs on a plane relate?
In his video Raymond explains how the diseases are transmitted through planes from one country to another and the difficulties faced to prevent the spread of diseases due to the air circulation in the planes. It is always difficult to screen the person with disease and prevent them from getting into the plane since the air circulates in the conventional cabins. When a person sneezes, the air will get swirled multiple times and spread the disease.
2. Using examples from the video, explain why it is difficult to keep people who are sick off of planes.
It’s difficult to pre-screen for diseases. When someone goes on a plane, they could be sick and actually be in this latency period in which they could have the disease but not exhibit any symptoms and could possibly spread the disease to many other people.
3. How does Wang illustrate what happens in a conventional airplane cabin when someone sneezes?
He illustrates how the air is just being circulated throughout the plane. When someone sneezes, the air is just being circulated into the air. This means that everyone on that plane has breathed in that person’s sneeze because it’s such a compact place.

Answer:
The Europeans, apart from doing their business through the Mississippi and Amazon, brought diseases to the native populations.
Explanation:
When the Europeans started to explore the Americas, they were trying their best to establish the best possible foundations for business and to make a big profit from it. This led to using everything that was at disposal, and the large rivers, like the Mississippi and Amazon, were excellent for easy travel and transportation over long distances. While these rivers served the Europeans very well, it brought tragedy to the natives.
Not always the Europeans were agressive to the native populations, but actually, more often than not they tried to establish good relations with them because in that manner they were able to have greater benefit. Unfortunately, through the interaction, the Europeans transmitted multiple diseases to the natives for which they did not have immune system capable of coping with them. This led to mass dying out of native populations. Both continents were heavily affected by this, and while often forgotten, the Amazon basin, with the new discoveries and what has been written in the exploration books by the Europeans, might have had several million-strong populations, which dissapeared in only a few decades.
