Answer:
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:
4.
Explanation:
Describe Wang’s solution for easily preventing the spread of disease on airplanes? What does “flow,” a word seen in the unit, have to do with his solution? The thing he made to prevent people from getting sneezes in their face is by making the bacteria flow straight towards the filters, so no one gets the bacteria in their faces.

give two examples of the thermal energy of a substance being decreased
Answer:
Adding ice to a glass of water causes the temperature of the water to decrease because the thermal energy in the water causes the ice to melt. A grill gives off thermal energy by burning propane.

Sort the phrases based on whether they represent kinetic energy or potential energy.
Answer: The main difference between potential and kinetic energy is that one is the energy of what can be and one is the energy of what is. In other words, potential energy is stationary, with stored energy to be released; kinetic energy is energy in motion, actively using energy for movement

How is biodiversity connected to healthy ecosystems? What is biodiversity?
Answer:
Below! : )
Explanation:
What is biodiversity? Well, in simple terms, biodiversity refers to all the variety of life that can be found on Earth (plants, animals, fungi, and micro-organisms) as well as to the communities that they form and the habitats in which they live. But how is biodiversity connected to healthy ecosystems? Well, many factors can contribute to this question but Biodiversity boosts ecosystem productivity where each species have an important role to play. With this in play we can see that it is healthy and keeps ecosystems safe.

How would the equilibrium change if the ocean became more acidic?
Answer: more H2CO3 is made
Explanation:
Acidic water of the ocean creates instability in the ocean ecosystem.
What happens when ocean become acidic?If the acidity of ocean increases the corals can't build skeletons and the shellfish also can't build the shells which they need for protection.
Corals are particularly important because they provide homes for many other sea creatures so we can conclude that acidic water of the ocean creates instability in the ocean ecosystem.

1. List 2 interactions between the earth spheres and the water cycle.
2. List 2 interactions between the earth spheres and the carbon cycle.
3. List 2 interactions between the earth spheres and the nitrogen cycle.
Answer:
The carbon cycle, as the nitrogen cycle, occurs in all the spheres: Biosphere, Atmosphere, Geosphere and Hydrosphere.
Explanation:
Most Earth events involve interaction between multiple spheres. For example, rain is the movement of water (the hydrosphere) from the atmosphere to the lithosphere where it collects in lakes, rivers, or streams. Water is an important resource for inhabitants of the biosphere.
The Atmosphere-contains all the air in Earth's system. The upper portion of the atmosphere protects the organisms of the biosphere from the sun's ultraviolet radiation. It also absorbs and emits heat. This sphere is also where weather occurs.
The nitrogen cycle occurs in all the spheres and ecosystems. It passes through rocks, water, atmosphere, plants, etc.
In atmosphere and biosphere: Nitrogen is about 78% of the gases in the atmosphere an it’s a essential component of the living organisms. It enters plants through the microorganisms that convert this nitrogen into ammonia. After this conversion, the plants absorb this substance. It can pass to animals when they eat these plants. Then, when they urinate, bacteria convert ammonia to nitrogen again and it returns to the atmosphere.
