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.
What substances do aquaporins allow to pass through?
Aquaporins allow water molecules to pass through cell membranes.
Are membranes selectively permeable if they allow only certain substances to move across them?
False.
What is the name given to membranes that only allow certain materials to pass through them?
"semipermeable"
Are the membranes in a dialysis machine premeable or selectively permeable?
The membranes in a dialysis machine are selectively permeable, meaning they allow certain substances to pass through while blocking others. This selectivity allows toxins and waste products to be removed from the blood while retaining essential substances.
Cells have selectively what membranes?
Cells have selectively permeable membranes that allow certain substances to pass through while blocking others. This selectivity helps maintain the internal environment of the cell by controlling the movement of molecules in and out.
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.
What type of molecules allow only certain molecules to pass through it?
semi permeable membranes
What type of membrane allows substances to pass through?
Membranes that allow passage in and out are called permeable.Membranes that only allow "some" substances to pass through aresemipermeable or selectively permeable.
Membranes that let some things through called selectively?
Semipermeable membranes. These membranes allow certain substances to pass through while blocking others based on size, charge, or other properties. Examples include cell membranes and dialysis membranes.
Do All membranes have exactly the same permeability characteristics?
No, all membranes do not have exactly the same permeability characteristics. Different membranes can have varying levels of permeability to different substances based on their structure and composition. Some membranes may be more selective in what substances they allow to pass through, while others may be more permeable.
When some substances can pass across them but others cannot?
membrane
