True/ False: Substances will diffuse more rapidly through a dense substance. Explain

Answers

Answer:

I'd say true

Explanation:

Mass of the molecules diffusing: Heavier molecules move more slowly; therefore, they diffuse more slowly. The reverse is true for lighter molecules. ... Because cells primarily use diffusion to move materials within the cytoplasm, any increase in the cytoplasm's density will inhibit the movement of the materials.

Answer:

False

Explanation:

As the density of a solvent increases, the rate of diffusion decreases. The molecules slow down because they have a more difficult time getting through the denser medium. If the medium is less dense, diffusion increases.

False because reflexes and snap reactions are generally bounced back directly from the spinal cord to save time. An example could be touching something hot because you react and move away instantly rather than your body burning for a second while the brain processes the information.

Answer:B

Explanation:

When the Earth's continental crust and ocean crust formed, they were different densities. Why did they differ in density and how did this affect their formation?

A.) The continental crust was thicker and less dense. It rose above sea level, separating land from water.

B.) The continental crust was thicker and more dense. It sunk below sea level, separating land from water.

C.) The continental crust was thinner and less dense. It rose above sea level, separating land from water.

D.) The continental crust was thinner and more dense. It sunk below sea level, separating land from water.


I think it’s B, but I’m not completely sure. Help please!

Answers

Answer: A.) The continental crust was thicker and less dense. It rose above sea level, separating land from water.

Explanation:

The Ocean crust is made out of rocks like basalt with a thickness of about four miles. The Continental crust on the other hand is made out of granite and other similar minerals and is between six and 47 miles in thickness which makes it thicker than the Oceanic crust.

With basalt being more dense than granite, the Oceanic crust sank and the Continental crust rose thereby separating land from water.

Answer:

Answer: A.) The continental crust was thicker and less dense. It rose above sea level, separating land from water.

✧･ﾟ: *✧･ﾟ:*    *:･ﾟ✧*:･ﾟ✧Explanation:✧･ﾟ: *✧･ﾟ:*    *:･ﾟ✧*:･ﾟ✧

Although the living reptiles birds are most closely related to are crocodilians (archosaurs), when it comes to their relation to dinosaurs, birds evolved from theropod dinosaurs. These theropods share over 100 traits with modern birds.
