Diffusion Questions and Answers (Q&A)

Lipids are not able to pass through cell membrane as they are simply too large to pass through the cell membrane and lipids are not able to pass through plain phospholipid bilayer.

The answer to this is letter B. Diffusion is the process by which the molecules will move through a permeable membrane from an area of higher concentration to an area of lower concentration. Diffusion is known to be important to a lot of organisms because, without proper diffusion, it will be harder for people to absorb the nutrients that their body needs.


It will also be harder for the body to get rid of the toxins that should be removed. Breathing is one of the examples of diffusion. The lungs make it a point to breathe in oxygen then carbon dioxide is also removed by the body.

Diffusion does not need to occur across a semi permeable membrane that is osmosis and active transport but not diffusion in general

(C) Carbon dioxide would diffuse out of the cell

One of the first things that will happen to this cell is carbon dioxide will flow out of the cell. This happens because carbon dioxide is a waste product, and there is more carbon dioxide inside this cell than there is outside the cell. The little ovals show carbon dioxide. Furthermore, there would be a movement of a protein into the cell.

Proteins are needed to make many things, and cells like to keep an equal balance between things inside the cell and outside the cell - becoming isotonic if you will. So, one protein molecule will move into the cell. On that same principle of balance, two carbon dioxide molecules will move out, putting three on each side of the cell membrane.

The colors will be the following: purple, dark purple, blue-black, then finally, black. Diffusion is known to be important to organisms because this is the process by which different molecules can provide the nutrients needed by the body. It is also through diffusion that the different waste products from the body can be removed.

This is important because if the body would not be able to remove wastes, then it will have a harder time to cleanse the body from toxins that the body does not need. It should be remembered that diffusion and osmosis are different from each other but they are both needed by the body.

The answer to this is false. The lipids may be too large to pass through the cell membranes if they do not dissolve but the thing is, they do dissolve. This means that even if they are too big, they would be able to get through. The lipid will always dissolve in solvents that are non-polar by nature.

There are also some types of lipids that can be found in the outer layer of your cells. There are also some lipids that will serve as the storage compounds of the body. One example of this is triglycerides. They are responsible for storing energy that the body may need in the long run. This explains why even if you are tired, you still have the energy to move.

The answer to this is letter D. All of the other given choices may refer to diffusion but it is only letter D that talks about the United States. It should be remembered that cultural items are unique from one country to another. It should not be assumed that just because something is made in the United States, it is already the most culturally relevant item that can be received.

There are a lot of other items coming from different countries that may be considered to be very nice and will also speak about their culture and even their traditions. It will be awesome to check the different items that countries from all over the world are offering.

Diffusion is defined as the transfer of particles from an area of higher concentration to an area of lower concentration. This is because diffusion is a property of equilibrium. It means that diffusion tries to find a state of uniformity in which the particles are of equal concentration everywhere. This can only take place with liquid and gas particles as solid particles are unable to move.

However, when solids are raised to a temperature where they melt, they also exhibit the property of diffusion. An extension of this property to water molecules is called osmosis. Here, water particles travel from an area of high-water concentration to an area of low water concentration.
