Answer:
In the given question, out of the four options
Option C. Facilitated diffusion
is correct.
Explanation:
In any hypertonic solution, flow of water is through the transporting channels known as 'aquaporins' which are embedded in the plasma membrane of the cell. Such type of transport is passive transport or passive movement of ions or molecules through a particular transmembrane protein integrated in it. This type of transport can also be referred to as passive mediated transport or commonly known as facilitated diffusion.
Answer:
He is industrious.
Explanation:
The purpose of rewriting is to clarify the message in a way that is easier to read and understand. In other words, the goal of rewriting is to convey the meaning of the message, while tightening the flow. This helps in eliminating redundancies.
Hence, in this case, we have the Rewriting of the original statement as "He is industrious."
Industrious simply means being diligent and hardworking
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: (b) Planet orbit shown as a moderately-flattened ellipse slightly wider than the others with the Sun at precise center of the ellipse. Minor axis is the same as other ellipses.
Explanation:
According to the first Kepler Law of Planetary motion, the orbit of a planet around the Sun, is in the form of an ellipse <u>with the Sun at one of the two foci of that ellipse</u>. This is also valid for any mass orbiting another mass greater than the first one in the space.
In this context, the ellipse is a conic, whose eccentricity is between 0 and 1. So, when its value is 0 we are talking about a circular orbit and when it is 1, a parabolic orbit.
That is, the nearer to the value of 1 (without reaching 1) the eccentricity of the orbit is, the more elliptical it will be.
In this sense, the only option that is incorrect is:
(b) Planet orbit shown as a moderately-flattened ellipse slightly wider than the others <u>with the Sun at precise center of the ellipse</u>. Minor axis is the same as other ellipses.
This statement contradicts Kepler's first law, because the Sun is <u>at one of the two foci of that ellipse</u>. The only way in which the Sun can be at the very center of the orbit is when we talk about a circular orbit. Since a circumference is a especial case of an elipse with eccentricity zero and we get only the center instead of the two foci.
Answer: amount of precipitation reaching the ground
Explanation:
A Doppler radar uses the Doppler effect when measuring return echoes after having sent a signal (in this specific case microwaves).
In the case of weather radars, a microwave signal is sent to a target and then reflected, so that the radar system measures this difference between the sent signal and the reflected signal.
So, a Doppler radar is is useful to determine the intensity of the precipitation and its location, <u>by calculating its motion, and estimating its type</u> (for example: rain or snow, among others). In addition, this type of radar is able to <u>determine the height and the structure of storms by detecting the motion of rain droplets</u>.
However, <u>weather radars are not capable to determine the amount of precipitation reaching the ground.</u>
