Answer:
Active transport:
- requires energy
- molecules move from low to high concentration sides
- Na+ and K+ move by active transport
Simple diffusion:
- molecules move from high to low concentration sides
- molecules pass between lipids
- small non-polar and polar molecules
Facilitated diffusion:
- molecules move from high to low concentration sides
- involves channel proteins
- move large molecules
Explanation:
- Simple Diffusion is the pathway of only small molecules that freely move through the membrane by momentary openings produced by the lipids' movements. Diffusion is a slow process that requires short distances and pronounced concentration gradients to be efficient. An example of diffusion is osmosis by which water is the transported molecule.
- Facilitated diffusion is the transport of hydrophilic molecules that can not freely cross the membrane. Channel protein and many carrier proteins are in charge of this transport. When uncharged molecules cross the membrane, they do it according to their concentration gradients, going from the more concentrated side to the lower concentrated one. When ions need to cross the membrane, the process depends on an electrochemical gradient. Glucose is an example of a hydrophilic protein that gets into the cell by facilitated diffusion.
Simple diffusion and facilitated diffusion are both passive transport processes because they only depend on electrochemical gradients, so they do not need any energy to occur.
- Active transport is the transport of molecules that move against the electrochemical gradient, so it does need energy to happen. Molecules move from the lower concentration side to the higher concentration side of the membrane. Carrier proteins are in charge of active transport. The needed energy might proceed from the ATP molecules or the membrane's electric potential. An example of molecules moved by active transport are the Na and K.
Answer: Please refer to:
A Mission Statement defines the company's business, its objectives and its approach to reach those objectives. A Vision Statement describes the desired future position of the company. Elements of Mission and Vision Statements are often combined to provide a statement of the company's purposes, goals and values.

<u>Complete Question:</u>
Nutria, Myocastor coypus, are large, semi-aquatic rodents native to South America. They were originally introduced in the US in 1889 for their fur. When the nutria fur market collapsed in the 1940's, thousands of nutria were released into the wild by ranchers who could no longer afford to keep them. Characteristics of the nutria include of those here EXCEPT
A. their status changed from introduced to invasive.
B. nutria affect the natural food web of the marshes.
C. nutria inflict permanent damage to marshes and other wetlands
D. nutria can only live in freshwater marshes in coastal areas along the Gulf
Coast.
<u>Correct Option:</u>
The characteristics of the nutria include of those here EXCEPT that "nutria can only live in freshwater marshes in coastal areas along the Gulf Coast".
<u>Option: D</u>
<u>Explanation:</u>
Nutria survives not only in freshwater marshes but also in wetlands, and can respond to various environments reasonably easily. In aquatic habitats, the species flourish and migrate rapidly across rivers into coastal wetlands. Nutria harm prone ecosystems can be seen in many ways.
Beyond destroying plants and crops, nutria kills the channels of ditches, streams, and other water bodies. Even so, the irreversible harm that nutria can do to marshes and other wetlands is of utmost importance. Nutria in these places rely on native plants which hold together wetland soil. This vegetation's degradation exacerbated the depletion of coastal marshes caused by sea level rise.
