5. Which of the following is an example of active transport?
Nadusha1986 [10]

Answer:

D (proteins moving ions from low to high concentration across a cell membrane)

Explanation:

Active transport, by definition, is a type of substance transport that requires energy (typically in the form of ATP). Having said that, we can immediately eliminate B (aka water diffusion throughout the cytoplasm of a cell), as diffusion (osmosis in this case) does not require any expenditure/spending of energy. Next, we can cancel A and C because although they do require energy, there is no transport involved. Thus that leaves us with D. D is not only the answer because of the process of elimination but also b/c the ans. choice says that ions are being moved from low to high concentration, which is against the concentration gradient and thus requires energy. Hope you found this helpful! :)

How does the structure of a nephron directly relate to function of the kidney
VLD [36.1K]
Nephrons are the filtering structures of the kidneys. The kidneys contain millions and millions of these tiny filtering structures that are responsible for cleaning the blood. Nephrons are responsible for removing excess water, wastes, and other substances in the blood that are not needed by the body. They also return necessary substances (e.g. sodium, potassium, phosphorus) whenever the body runs low in supply.  

If these nephrons are damaged, blood will not be properly filtered. As a result, the kidney will have different diseases and this might lead to kidney and multiple organ failure.       <span> </span>

Why does conduction occur more easily in solids and liquids, than in gases?
blsea [12.9K]

Answer:

Because liquids and solids are denser than gasses.

Explanation:

Solids and liquids are denser than gasses making it easier for things like sound to conduct through them. Being dense contributes to a better conduction because the particles and such within the solid or liquid are closer together which allows for things like sound to travel at a much faster rate because they're so much easier to vibrate.
