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.
The answer is the ocean-continental convergence. This is where the gold of the Inca civilization come from.
The correct answer for the question that is being presented above is this one: " drier and cooler." Ocean currents that upwell near Southern California can make the climate drier and cooler compared to coastal areas that do not have upwelling.
Answer:
Photosynthesis play important role in the cycling of matter into and out of the organisms as photosynthesis is the process in which plants utilize carbon dioxide (CO2) and water (H2O) and releases oxygen (O2) and energy in the form of carbohydrate or sugar. Other organisms utilizes these oxygen and energy or carbohydrate for the chemical reaction in their body.
So, photosynthesis take carbon dioxide (CO2) and water (H2O) from outside as input and gives oxygen (O2) and energy as output.
