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:
1. The air circulates in the cabins so when a person sneezes the air will get swirled around multiple times and spread the disease.
2. Many diseases like sars, don't show up on simple testings and the person could have a disease early on and it would be nearly impossible to identify.
3. He illustrates how the air is being circulated throughout the plane. When someone sneezes, the contaminated air is being circulated throughout the plane. This means that everyone on that plane has breathed in that person’s sneeze because it’s so compact.
4. Wang’s invention can stop the spread of disease because it pushes all of the air down meaning if someone coughed or sneezed, instead of spreading around the cabin, the air would get pushed down to the filtration system before reaching multiple people. The word “flow” has to do with his solution because he is redirecting the flow of the air in the airplane downwards to prevent more people from getting sick.
You are 10°N and 30°E; you move to a new location that is 25° south and 40° west of your present location. What is your new latitude and longitude position?
If we are 10'N and 30°E and we move to a new location that is 25 south and 40" west of our present location. Our new latitude and longitude position will be 15' south 10 "west latitude and longitude.
What is longitude?Longitude is a geographic coordinate that specifies the east–west position of a point on the surface of the Earth, or another celestial body. It is an angular measurement, usually expressed in degrees and denoted by the Greek letter lambda. Meridians are semicircular lines running from pole to pole that connects points with the same longitude.
The prime meridian defines as 0° longitude; by convention, the International Reference Meridian for the Earth passes near the Royal Observatory in Greenwich, England on the island of Great Britain. Positive longitudes are east of the prime meridian, and negative ones are west. Because of the Earth's rotation, there is a close connection between longitude and time measurement.
Scientifically precise local time varies with longitude: a difference of 15° longitude corresponds to a one-hour difference in local time, due to the different positions about the Sun.

Answer:
B
Explanation:
If plates are moving and storing energy especially along faults, earthquakes are gonna happen if not already happening.
Geologists know that wherever plate movement stores energy in the rock along faults, earthquakes are likely. The correct option is B. Earthquakes are expected wherever plate movement stores energy in the rock along faults, according to geologists.
What causes an earthquake?Earthquakes are typically caused by underground rock suddenly breaking and rapid movement along a fault. The seismic waves that cause the ground to shake are caused by this sudden release of energy.
Radioactive energy in the Earth's mantle provides the energy for earthquakes. The heat produced by radioactive decay causes convection in the mantle. This movement is transferred to the Earth's crust, where it stores energy in rocks, similar to how a spring is stretched.
Thus, the ideal selection is option B.

Statements describe evidence of continental drift are Mountain ranges often appear on the edges of continents and Fossils of the same animals appear on different continents. Option (b) and (c) are correct.
What do you mean by Range?The difference between the highest and lowest values for a given data collection is the range in statistics.
The fit of the continents, the distribution of prehistoric fossils, rocks, and mountain ranges, as well as the placements of prehistoric climatic zones, were all used as evidence for continental drift.
They used a variety of pieces of evidence to support their theory of continental drift, including the fit of the continents, paleoclimate indicators, truncated geologic structures, and fossils.
The first piece of evidence presented by Wegener was the similarity of some continents' coasts to jigsaw puzzle pieces. On the first world maps, people saw parallels between the coastlines of South America and Africa, and some speculated that the continents had been torn apart.

Which statement is true of wind currents?
Wind currents flow in regular patterns depending on the latitude through which they are moving.
Winds and air currents flow in random patterns that are difficult to predict.
Because of the Earth’s rotation, wind currents all over the globe tend to blow from the southeast or east.
Warm air in the temperate zones sinks below the cold air of polar regions.
Answer:
I'm pretty sure the answer is number 3
In meteorology, concentrated zones of winds are known as air currents. They primarily result from variations in the temperature or atmospheric pressure. Hence option C is correct.
What is Wind Current ?Both horizontal and vertical currents are present at the mesoscale, whereas horizontal currents predominate at the synoptic scale. In addition to the troposphere, the stratosphere and mesosphere also contain air currents.
The uneven heating of the Earth's surface is what causes air currents in the atmosphere. Water currents in the ocean are brought on by winds or variations in density.
The Trade Winds, the Prevailing Westerlies, and the Polar Easterlies are these three. As though there were wind belts encircling the planet, each of them governs an area of about 30 degrees latitude.
The Earth's rotation and temperature variations, particularly the differential in heating at the equator and the poles, affect the pattern of the worldwide atmospheric circulation. By moving heat and water, winds affect regional climate and everyday weather.

Answer:
it look like a mountain
Mountain is featured that is forming. Hence, option A is appropriate.
What is a mountain?A mountain is indeed an elevated area of the crust of the earth, typically having steep sides that reveal a substantial amount of bedrock that has been exposed. Although variations exist, a mountain is often taller than a hill, normally rising at least 300 meters above the surrounding terrain, and differs from such a plateau in having a constrained peak area.
Mountains serve as the "water towers" of the earth, supplying 60–80% of the world's freshwater supplies. The survival of at least 50% of the world's population depends just on water, food, and clean energy provided by mountain ecosystem services.
Mountains offer water for drinking, hydroelectricity, agriculture, food production, shelter, fresh water, and other uses. Explanation: Rivers and lakes receive their water from the snow and glaciers of the mountains. The water is used for drinking, food preparation, irrigation, and electrical production, among other things.
Hence, option A is correct.

The linear parent function is transformed to create the new function g(x)=12f(x−13). What is the correct description of the transformations.
The new function g(x) is less steep than f(x) and shifted to the left 13 units.
The new function g of x is less steep than f of x and shifted to the left 13 units.
The new function g(x) is steeper than f(x) and shifted to the left 13 units.
The new function g of x is steeper than f of x and shifted to the left 13 units.
The new function g(x) is steeper than f(x) and shifted to the right 13 units.
The new function g of x is steeper than f of x and shifted to the right 13 units.
The new function g(x) is less steep than f(x) and shifted to the right 13 units
Answer:
The new function g(x) is steeper than f(x) and shifted to the left 13 units.
Explanation:
Given
[tex]g(x) = 12f(x - 13)[/tex]
Required
Determine the relationship between f(x) and g(x)
First, we need to determine the direction which f(x) is shifted to (right or left)
For a function f(x)
f(x - h) implies that f(x) is shifted right by h units
So, f(x - 13) implies that f(x) is shifted right by 13 units
Next, we determine the steepness of f(x) and g(x)
We can assume that the steepness of f(x) is 1
The steepness of g(x) can be determined as follows:
[tex]g(x) = 12f(x - 13)[/tex]
[tex]g(x) = 12 * f(x - 13)[/tex]
Hence, the steepness of g(x) is 12
Going by the analysis above:
g(x) is steeper and f(x) is shifted 13 units right to get g(x)

Explanation:
During part 3 of the cycle, water breaks the rocks apart to form sediments.
Part 3 is the erosion and weathering phase.
Weathering is the physical disintegration and chemical decomposition of rocks to form soils. Water is the main agent of denudation that causes the erosion and weathering of rocks. Erosion carries the weathered materials from their site of disintegration. These sediments are then transported and deposited to form sedimentary rocks.In 1993, North Korea withdrew from
