Diffusion fMRI (dfMRI) was proposed to overcome these limitations: it relies on dynamic microstructural changes driven by neural activity, such as cell swelling, to induce changes in the diffusivity of water molecules onsite. While some studies show water diffusion decreases following stimulation [1,...
(Hint: Consider the relationship between temperature and the speed at which particles move.) In what way does size affect the rate of diffusion? Describe the factor that affects the rate of diffusion. Describe two variables that effect the rate of diffusion?
Is osmosis an active transport of passive diffusion? Why is the direction of water in osmosis from both sides of the cell membrane even when one of them is a concentrated solution, then how can something move from lower to higher concentration?
Osmosis is the passage or diffusion of water or other solvents through a semipermeable membrane that blocks the passage of dissolved solutes [source: Encyclopedia Britannica]. What, you don't get it? No fear. Most of us don't, which is why there are countless explanations and analogies to ...
Learn more about this topic: Kinetic Theory of Matter | Definition & Overview from Chapter 2/ Lesson 12 369K Learn about the four states of matter, the kinetic theory of matter, and how it relates to how matter is able to change from one phase to another. ...
diffusion, to the outside: unlike with many other textiles, the water doesn't move by wicking and capillary action (where the water soaks into the fabric and then channels through it, like water moving up a plant from the roots to the leaves), but because of the difference in water ...
According to this view, search-and-rescue operations increase the crossing risk by encouraging smugglers to move from wooden boats to inexpensive, inflatable boats, ultimately increasing mortality along the CMR22 (see also a study employing the maritime traffic through the Suez Canal as an ...
1)Across cell membranes, oxygen and carbon dioxide move or transport via simple diffusion, and no...
What controls the amount of water in each compartment? Explain the difference between osmosis and diffusion. Which electrolytes were out of the normal range and in which direction? Explain how osmosis is influenced by molecules and ions? Explain the role of ADH in maintaining water balance, betwee...
How does diffusion vary from gas to liquid to solid? Explain how convection currents are produced in the air. How does salinity affect density? How does heat move from one place to another in the troposphere? How does the polar property of water relate to cohesion?
