Is osmosis the way very small molecules get in and out of the cell by passing through small openings in the cell membrane?

Yes. As well, larger molecules, that are permitted entry into the Cell by other means, transport themselves throughout the Cytoplasm to numerous destinations including the Nucleus via, it would appear, diffusion.


What are the mechanisms involved in diffusions of a cell?

There are 2 processes by whicha cell can get what it needs to live. These are 1) Active transport where the cell must expend some energy to move something into the cell (like food molecules) and out of the cell (like waste). The other 2) diffusion/osmosis. Diffusion is a process where things move from areas of higher concentration to areas of lower concentration without expending any energy, like the smell of bacon cooking in a kitchen filling an entire house. Try dropping a drop of food coloring into a glass of water and, without stirring, check it a few hours later. Osmosis is the diffusion of water.


How can you use a visking tube to test the hypothesis that osmosis happens faster at higher temperatures?

Put a sucrose solution into the visking tube and fasten the ends, then place it in water (at different temperatures). The varying temperatures would quicken or slow the rate of diffusion (osmosis). Then using iodine, you put some in the water that the visking tube was in and if it turns dark blue/black the more sucrose has diffused. This can be put into a calorimeter to check the intensity for different temps. You should find that the higher the temp. the higher the rate of diffusion (because particles are excited and have more kinetic energy and move more). Hope this helps =) Sana (17 yrs)


What allows potassium to diffuse in and out of cells?

Potassium diffuses in and out of cells through potassium channels, which are membrane proteins that selectively allow potassium ions to move down their concentration gradient. These channels help maintain the resting membrane potential and are crucial for many cellular processes, including nerve signaling and muscle contraction.


How can someone diagnose HTTP 403 Forbidden Error?

A HTTP 403 Forbidden Error typically indicates that the server understood the request, but is refusing to fulfill it. This can be due to inadequate permissions, misconfigured server settings, or restrictions set by the website or server administrator. To diagnose this error, check the server logs for more details on why the request was forbidden and ensure that the necessary permissions and configurations are in place.

What are tiny vessels which diffusion takes place between the blood and the body tissues?

Capillaries are tiny blood vessels where diffusion takes place between the blood and body tissues. Their thin walls allow for the exchange of oxygen, nutrients, and waste products between the blood and the surrounding tissues.

What influence cell diffusion?

Several factors influence cell diffusion. For example, the polarity of the molecule to be diffused and the size of the molecule. Both of these factors may determine whether or not diffusion will be passive or facilitated. The lipid bi-layer of the cell membrane favors lipid soluble molecules and will allow quick passive diffusion of these molecules. Water soluble molecules may need to diffuse through protein channels, lipid rafts phagocytosis or facilitated diffusion. Check Wikipedia for definitions of these processes.
