What else can I help you with?
What do you call a thin solids that allow certain substances to diffuse through them?
Semi-permeable membranes are thin solids that allow certain substances to diffuse through them while preventing the passage of others.
Can pores or openings that allow liquides or gass to pass through?
Yes, pores are small openings that allow liquids or gases to pass through. They can be found in materials like membranes, filters, and biological tissues, serving as pathways for the movement of substances. Pores help regulate the flow of fluids and gases in various systems.
In fact polar molecules are unable to go across unless?
In fact, polar molecules can pass through cell membranes with the help of specific transport proteins that facilitate their movement. These transport proteins act as channels or carriers to allow polar molecules to cross the hydrophobic membrane. Therefore, polar molecules can indeed pass through cell membranes under certain conditions.
What are three materials that convection is made of?
Convection can occur in liquids, gases, and plasmas. These materials allow for the transfer of heat through the movement of their particles, either through natural or forced convection processes.
How is electricity conducted through different materials?
Electricity is conducted through different materials based on their ability to allow the flow of electric charge. Materials that conduct electricity well, such as metals, have free-moving electrons that can carry the charge. Insulating materials, on the other hand, do not allow the flow of electric charge easily. The conductivity of a material depends on its atomic structure and the availability of free electrons.
What are membranes that allow only certain substances to pass through them?
Semi permeable membranes.
What is the name given to membranes that only allow certain materials to pass though them?
semipermeable
What is the name given to membranes that only allow certain materials to pass through them selectively permeable?
The term used to describe membranes that allow only certain materials to pass through them is "selectively permeable" or "semipermeable." These membranes enable the selective transport of substances, allowing some molecules to pass while restricting others. This property is crucial for maintaining homeostasis in biological systems, as it regulates the internal environment of cells.
How many shell membranes in egg?
Eggs have selectively permeable membranes, just like those of cells (they can only allow certain materials or objects to pass through, kind of like a screen door).
What type of molecules allow only certain molecules to pass through it?
semi permeable membranes
What materials are permeable to some ofthe substances but impermeable to the others?
Semi-permeable membranes are materials that allow certain substances to pass through while blocking others based on their size and charge. Examples include cell membranes in living organisms and dialysis membranes used in medical treatments. These membranes play a crucial role in biological processes and separations in various industries.
Does selectively permeable membranes allow only certain materials to pass through them?
Yes, selectively permeable membranes allow only certain materials to pass through while restricting others. This selectivity is based on factors such as size, charge, and solubility, enabling the membrane to maintain homeostasis within a cell or compartment. For example, small nonpolar molecules can often pass freely, while ions and larger molecules require specific transport mechanisms.
What do you call a thin solids that allow certain substances to diffuse through them?
Semi-permeable membranes are thin solids that allow certain substances to diffuse through them while preventing the passage of others.
What is the function of a selectively permeable membranes?
selectivley permeable membranes only allow certain materials to pass through.It allows some molecules to enter the cell and blocks entry to others.
What does Osmosis includes?
All the actions of semiperiable membranes : surfaces that allow some materials to pass through but not others. USUALLY the term osmosis refers to membranes that pass water but not other substances.
What are materials that allow light to pass through them?
Materials that allow light to pass through are called transparent materials. Common examples include glass, certain plastics, and water. These materials have a uniform composition that allows light to pass through without significant scattering or absorption.
What membranes allow some materials to pass while constraining the movement of other molecules.?
Semi permeable membranes as the plasma membranes in cells of our body.
