A substance that allows water and air to pass through is called a permeable material. This type of material has spaces or pores that facilitate the flow of water and air through it, making it suitable for applications like drainage systems, filtration, and breathable fabrics. Examples of permeable materials include sand, gravel, and certain types of membranes.
A transparent substance allows light to pass through it freely, resulting in visibility through the material. In contrast, an opaque substance blocks light from passing through, making it impossible to see through the material.
Water is transparent, meaning that it allows light to pass through with very little absorption or scattering. Plastic wrap is also considered to be transparent as it allows light to pass through with minimal interference.
A substance that does not let heat pass through it is called an insulator. Insulators are materials that have low thermal conductivity, meaning they are poor conductors of heat. This property allows them to prevent the flow of heat energy.
"Porous" refers to a material or substance that has small holes or spaces that allow liquid or air to pass through. This characteristic of porosity allows for absorption or filtration in various applications.
Cell membrane allows sugar and water to pass through due to the presence of transport proteins such as glucose transporters and aquaporins. These proteins facilitate the movement of these molecules across the cell membrane through passive or active transport processes.
A substance that allows light to pass through it is called transparent. This means that it doesn't obstruct or absorb the light rays passing through it, allowing them to pass through with minimal reflection or refraction. Examples of transparent substances include glass, water, and air.
Opaque is antonym for transparent. Transparency allows light to pass through. Glass, water are examples. If light is not allowed to pass through then such a substance is termed as opaque.
A substance that allows electricity to easily pass through it is called a conductor, examples include metals like copper and aluminum. Conversely, a substance that allows heat to easily pass through it is called a thermal conductor, examples include metals like silver and copper.
An electrolite
A substance that allows electricity and heat to pass through is known as a conductor. Conductors have free-flowing electrons that can carry electrical current and also facilitate the transfer of heat energy through the material. Metals such as copper and aluminum are common examples of good conductors.
water can pass through cell membranes by osmosis- similar to diffusion
Biological membrane, cell membrane, fetal membranes: amnion, chorion,
A substance that allows electricity to pass through it is called a conductor. Examples of conductors include metals like copper and aluminum, as well as materials like graphite and saltwater.
percolation
a substance which has a low resistivity and allows a large amount of current to pass through
The body of water that allows people to pass through from one side of the Americas to the other is an enclave.
Pervious surfaces are materials or surfaces that allow water to pass through them, such as grass, gravel, or permeable concrete. This helps to reduce stormwater runoff and allows rainwater to be absorbed into the ground, replenishing groundwater supplies.
