Liquid solids are the particles that come from liquid. This goes through a membrane.
Powdered charcoal particles are too large to pass through the pores of a membrane due to their size. The membrane acts as a barrier that only allows smaller molecules or particles to pass through, thus retaining the charcoal particles on one side of the membrane.
Small particles can pass through the cell membrane by simple diffusion. If the particles are water, the process is given a special name: osmosis.
A+ reverse osmosis
Filtration separates mixtures based on particle size. Larger particles are trapped by the filter, while smaller particles pass through, resulting in the separation of the components of the mixture.
Reverse Osmosis is the method of producing pure water by forcing saline or impure water through a semipermeable membrane across which salts or impurities cannot pass. Reverse osmosis is used for water filtration, for desalinization of seawater, and in kidney dialysis machines.
Yes
When a cell needs to take in a particle larger than the membrane channels can passage, it will invaginate the cell membrane around the particle(s) and pinch off part of the membrane containing the particles inside the cell membrane. This is called phagocytosis (when the particles are primarily solid) or pinocytosis (when the particles are primarily liquid).
Yes, that is very true, especially with osmosis (the passing of water through a selectively permeable membrane).
The cell membrane separates the cell from its surroundings and controls what can enter and exit the cell through a selective barrier called the lipid bilayer. This barrier allows certain substances, such as nutrients and waste, to pass through while blocking others.
Yes, oxygen particles would enter a cell through diffusion more readily than fat particles due to their smaller size and higher solubility in the cell membrane. Fat particles are larger and less likely to pass through the cell membrane via simple diffusion.
The Lugol's solution particles were able to cross the model cell membrane, while the starch particles were too large to pass through. Starch is a large molecule that cannot diffuse across the membrane, while Lugol's solution contains smaller molecules (iodine and iodide ions) that are able to pass through.
By diffusing across the protein membrane.
