What else can I help you with?
What is very effective at dissolve other polar substances because of its?
Because it is hydrophilic...."water-loving." Examples of these are sugars, salts and ions. :)
What is a reverse osmosis membrane?
A reverse osmosis membrane is a thin, semi-permeable barrier that allows water molecules to pass through while blocking larger molecules like contaminants and impurities. It is a key component in reverse osmosis systems used for water purification by removing dissolved minerals, particulates, and other harmful substances from water.
Why is oxygen typically an oxidizing agent?
Oxygen is typically an oxidizing agent because it has a strong tendency to gain electrons from other substances, causing them to lose electrons and undergo oxidation. This property allows oxygen to facilitate chemical reactions where other substances are oxidized.
What is it called when vesicles are used to move substances out of the group?
Exocytosis is the process where vesicles fuse with the plasma membrane to release substances outside of the cell. This mechanism allows cells to expel waste or deliver molecules to other cells.
Why does cyclohexanone dissolve in benzophenone and not in water?
Cyclohexanone and benzophenone are both non-polar. Water is polar. "Like dissolves like" so non-polar substances dissovle other non-polar substances and polar substances dissolve other polar substances.
What allows some materials to pass through it but keeps other materials out?
A selectively permeable membrane allows only certain molecules or substances to pass through, based on their size, charge, or other properties. This membrane acts as a barrier that can control the passage of specific substances while blocking others.
The cell membrane forms a protective barrier between the external and internal environments. It is referred to as because it allows some substances to cross more easily than others and blocks other su?
The affirmation is correct.
Does the cell membrane control what goes in and out of a plant cell?
Yes, the cell membrane in a plant cell acts as a selective barrier that controls the movement of substances in and out of the cell. It allows essential molecules such as water and nutrients to enter the cell while regulating the exit of waste and other substances.
Why is another word for selectively permeable?
Another word for selectively permeable is semipermeable. This term describes a membrane or barrier that allows certain substances to pass through while blocking others based on size, charge, or other characteristics.
What is the function of cell membrain?
It is what allows things to enter and exit the cell
What protects the CNS from harmful substances and pathogens by preventing passage of these substances from blood into the interstitial fluid of brain tissue?
The blood-brain barrier is a protective mechanism that regulates the passage of substances from the blood into the interstitial fluid of the brain tissue. It consists of specialized endothelial cells that line the capillaries in the brain, tight junctions between these cells, and other supporting cells like astrocytes. This barrier helps protect the central nervous system (CNS) from harmful substances and pathogens.
Is plasma membrane premeable?
The plasma membrane is selectively permeable; it allows some substances to pass through but prevents the passage of other substances
What is permeable barrier?
A permeable barrier is a structure or material that allows certain substances, such as liquids or gases, to pass through while blocking others. It is commonly used in environmental engineering to control the flow of pollutants or contaminants while allowing water to filter through. Materials like geotextiles, gravel, or sand can serve as permeable barriers in various applications.
What is the function of plasma membrain?
All cells have a plasma membrane that encloses their contents and serves as a barrier to the outside environment. The membrane acts as a boundary, holding the cell constituents together and keeping other substances from getting in. But the plasma membrane does allows nutrients and other essential elements to enter the cell and waste materials to leave the cell. Small molecules, such as oxygen, carbon dioxide, and water, are able to pass freely through the membrane, but the passage of larger molecules is controlled.
Which blood vessel allows substances to travel between the blood and other cells in the body?
capillaries
What organelle controls what goes in and out of the cell?
Cell wall
What is the structural reason that meat is wrapped in plastic in grocery stores?
Here are a couple reasons: # Plastic wrap is clear and allows the consumer to see what they are buying. # Plastic wrap is a good moisture barrier and will help prevent drying out and leaking while keeping it protected from other contaminants.
