proteins and cells remain in the blood
fats, oils, lipids are all hydrophobic.
The cell would be unable to maintain a stable internal environment.
Albumin is a large protein molecule that does not readily pass through the tight junctions of the blood-brain barrier (BBB), which selectively regulate the passage of substances between the bloodstream and the brain. Due to its size and structure, albumin is unable to diffuse through the BBB, resulting in limited entry into the brain.
Selective (or differential) permeability allows the cell to regulate its internal environment and maintain internal homeostasis. This is also the basis by which a neuron (nerve cell) can 'fire' and send a message along its axon - it selectively allows one electrolyte then a different electrolyte to flow across its cell membrane and change the electrochemical gradient.
The primary affect urbanization has on temperature is to increase it overall. Because of the concentration of people, buildings, and equipment, nature is unable to dissipate all the heat as it normally would.
Because of the esophageal sphincter (or cardia)
Substances that are unable to dissolve in water are considered hydrophobic. This includes substances such as oil, fats, and waxes. These substances are non-polar and do not interact well with the polar water molecules, leading to limited or no solubility.
Glucose is absorbed in the nephron of the kidney, if it is present in very high amounts or unable to be reabsorbed, like with diabetes, it will be present in urine.
It is called "Addiction"
A molecule that is too large or charged would be unable to diffuse through a cell membrane.
Immunodeficiency
Mephibosheth was disabled in both feet, making him unable to walk normally.
He was unable to see through a microscope. (Discussed in "My Life and Hard Times")
fats, oils, lipids are all hydrophobic.
The solid particles collected in a filter paper are known as the residue. These are the substances that were unable to pass through the filter paper and were left behind during the filtration process. They can be further analyzed or disposed of depending on the experiment.
Electricity is unable to pass through them
