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:
Tok Pisin a native language of Papa New Guinea, an isolated country.
Hiri Motu a second native language of Papa New Guinea, an isolated country.
Explanation:
Isolated languages can persist over time due to the lack of outside influence of other languages that allow for the morphing of language from its roots in its origin.
100% China. You're welcome ;)
Answer:
A. Weathering, vegetation covering, and water influence the stability of a slope.
Explanation:
- As water tends to flow down by the act of gravity the flow of the water down the slope will make the unconsolidated sediments to flow down the slope and thereby making the slope more prone to weathering and not stabilization it hence the flow tends to move down the rocks, silt and loose particles and thus making it me prone to weathering and erosion.
- <u>Thus the flowage of the matter will create more impacts on the slope angle and width as it will spread more faster and extensively.</u>
