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.
According to the First World War page on the Australian War Memorial website from a population of fewer than five million, 416,809 men enlisted, of which over 60,000 were killed and 156,000 wounded, gassed, or taken prisoner. The latest figure for those killed is given as 62,000.
Answer: See explanation.
Explanation:
Because Astronomers have well-tested theoretical models that explain how a star evolves over the course of its life as well as well-tested theoretical models that explain how a star evolves over the course of its life.
I believe the answer is C. This is because all three headlines include information about transportation systems (first one with air delays, second with road closures and third with roads being reopened) being effected by natural disasters.
Here are why the other ones are incorrect:
A. In headline 2 with Arizona, it states how wildfires caused road closures around the state and not the area of the wildfire (headline 1 also disproves this answer, since it says “Worst delays since 9/11”, meaning it effected a lot more than the nearby area).
B. None of these are predicting natural disasters occurred, as seen by some of the language: “Arizona Fires FORCE road closures” (present tense, not past).
D. These do not mention anything about railroads being immune, so it can’t be it.
Hope this helps!
