How does non-permeability work?
Non-permeability refers to the property of a material that prevents substances from passing through it. This can be achieved through various mechanisms, such as dense molecular structures, impermeable coatings, or tight seals. Non-permeable materials are commonly used in applications where preventing the passage of liquids or gases is essential, such as in plumbing systems or food packaging.
What is the process of separating dissolved substances by passing them through a porous material?
The process is called filtration. It involves passing a mixture through a porous material, like filter paper or a filter membrane. The dissolved substances are trapped on the filter, while the solvent passes through.
How does the temperature of a material affect the speed of sound passing through it?
Temperature is a fact for speed. Speed is increasing with the temperature.
Why Cell membranes are not permeable to anthocyanin. If the anthocyanin appears in the solution what must have occurred?
Cell membranes are not permeable to anthocyanins due to their large size and polar nature, which prevent them from easily passing through the lipid bilayer. If anthocyanin appears in the solution, it suggests that the cell membranes have been compromised, possibly through damage or the use of solvents that disrupt membrane integrity, allowing the anthocyanin to leak out of the cells.
Water pass true the cell membrain what does it call?
Water passing through the cell membrane is called osmosis. Osmosis is the movement of water molecules from an area of higher concentration to an area of lower concentration across a selectively permeable membrane.
How do particles move through a permeable membrane according to diffusion?
Yes, that is very true, especially with osmosis (the passing of water through a selectively permeable membrane).
What stopps electrons from passing through a material?
magnetism
The passing of genetic material from parent to offspring is?
true
Why is a plastic bag selectively permeable?
Does not allow matter to pass, but energy (light, heat, etc) is allowed to enter.
What is something covered with material that keeps warmth of sound from passing through it?
A material that can block the warmth of sound from passing through it is called a soundproofing material. This material is designed to absorb or reflect sound waves, preventing them from passing through and thus reducing noise transmission. Materials such as fiberglass, foam panels, mass-loaded vinyl, and soundproof curtains are commonly used for this purpose.
After passing through the proximal convoluted tubule urine filtrate flows where?
Afferent arteriole -> Glomeruli -> Bowman's capsule (ultrafiltration) -> PCT (Highly permeable to water and solutes, brush border enzymes) -> Loop of henle (descending: water permeable, ascending: solute permeable) -> Early PCT (solute permeable) -> Late PCT and cortical collecting duct (principal cell - permeability depends on hormones ADH and aldoesterone and intercalated cell: secrtes H+)-> Medullary collecting duct (principal cell) -> Ureter -> Bladder -> Urethra
What is the passing of heat through a material called?
sound waves
What does anaerobic bacteria do in the large intestines?
they eat the material passing through
What material is responsible for passing on genetic instructions in the nucleus?
the cell membrane
What conitans bacteria that fees on material passing through?
large intestine
Why is clay the least permeable soil?
Clay has the smallest particle size. The particles of clay soil pack so closely together that water is prevented from passing through it.
What is a piece of clear material that bends light rays passing through it?
Glass.reflection
