Do clay soils have more permeability than sandy soils?
Sandy soils are much more permeable that clay soils.
Why are some rocks more permeable than others?
Some rocks are softer and more sedimentary than others. This allows water to weather them faster, thus causing higher permeability.
Which is more permeable silt or sand?
sand
Is sand more permeable than clay?
Yes, sand is more permeable than clay since sand contains bigger particles and bigger particles equal greater permeability.
What are collapsible soils?
The soil which exhibit more volume change at time of saturation.Those soils are called collapsible soil. Ex:- Loess
Do clay soils have more permeability than sandy soils?
Sandy soils are much more permeable that clay soils.
What is a membrane that allows some substances to pass through but excludes others?
A membrane that lets some substances pass through but not others is known as a semipermeable membrane. Other terms that describe this type of membrane are: selectively permeable, partially permeable, or differentially permeable.
Why does different kinds of soil hold more water?
different soils can drain better than others
Which is more permeable fine sand course sand or soil?
Fine sand is more permeable.
How does the cell wall limit the cell?
A cell wall makes a cell more rigid and makes it less permeable which is beneficial as it can prevent stuff from easily flowing in or escaping.
Why are some rocks more permeable than others?
Some rocks are softer and more sedimentary than others. This allows water to weather them faster, thus causing higher permeability.
What is the roleof anti-diuretichormone (ADH)in the body?
ADH makes the collecting duct & distal convoluted tubule of the nephron more permeable to water
What is the role of anti diuretichormone (ADH) in the body?
ADH makes the collecting duct & distal convoluted tubule of the nephron more permeable to water
Are Excitable cells like neurons are more permeable to sodium than to potassium?
More permeable to K than Na
What is the role of anti-diuretic hormone (ADH) in the body?
ADH makes the collecting duct & distal convoluted tubule of the nephron more permeable to water
Why are soils generally less fertile than clayey soils?
Sandy soils are generally less fertile than clay soils because they do not hold water as well as clay soils. Clay soils are usually fertile and hold more nutrients than sandy soils.
What would happen to the membrane potential if a substance that makes the membrane permeable to ions is added to the cell?
If a subsance is applied to a cell that makes the membrane more permeable to ions, the interior voltage changes. If the interior voltage becomes more positive (say from Ð70 mV to Ð60 mV), this is called a depolarization. If the interior voltage becomes more negative (say from Ð70 mV to Ð80 mV) it's called a hyperpolarization.
