A saline solution with 1.5% saline would be considered hypertonic when going in the body. The blood in our bodies has a saline concentration of 0.9% on average. A hypertonic solution, for those who don’t know, is a solution that has more salt than what it’s going into. It’ll cause the salt in itself to move into the solution it’s going into (IE, your blood, if it’s a saline solution for your body).
Once the solutions equal out, the solutions would be considered isotonic. This is when two concentrations of a solvent (in this case, salt) are the same in two different solutions. Water will still move back and forth, as that is what the water does, but the salt will no longer move back and forth.
Starch cant because it is too big to go through the partually- permable membrane
The equilibrium is reached is number 3. The dissolved sugar molecules are evenly distributed throughout the solution. Some may think that the salt solution and sugar solution is the same but there are some differences between the two.
For example, in salt solution, the salt will mix with the water but through the process of evaporation, the salt can be separated again from the water. When it comes to sugar, the sugar will just completely dissolve with the water. This is the moment when the sugar will truly reach equilibrium. The sugar dissolves because the use of energy is required in order to form bonds with the water molecules that are available.
Both of this guys the wrong idea the real answer is 3 because it goes across the membrane and that is why the dye molecule is know going through the bottle. I'm sorry that this people didnt know the answer
Some people assume that effusion and diffusion are the same, but this is not true. Diffusion is known to be the movement of particles from one place to another place that comes with a higher temperature. An example of this is the smell of perfume.
When you spray it, you do not immediately smell it, but when you do, you know that the particles have already diffused successfully. Effusion refers to the movement of the glass particles through a small hole. Even though there are differences between the two, it cannot be denied that they are similar to each other because of the similarities in the movement of gas and gas behavior.
The answer to this is Facilitated Diffusion. Facilitated diffusion is the process by which the passive transport of molecules and ions through a passageway going to the integral membranes. Usually, the molecules that would need to undergo this process would move in and out of the cell membranes. Some of the most common ones are sodium ions, potassium ions, and glucose.
They would need to use carrier proteins in order to get to their needed location easily within the body. The other processes that are given as options are used for other purposes. For example, osmosis is another process that happens in the body but this is needed by solvent molecules.
Endocytosis, pinocytosis and phagocytosis are means of taking in materials into the cell membrane.
Endocytosis is a cellular process of taking materials by invagination of the cell membrane to form a vacuole.
Pinocytosis is a cellular process of taking materials (mostly liquid) into the cell by budding of small vesicles from the cell membrane.
Phagocytosis is a cellular process of taking materials (foreign bodies such as bacteria) by phagocytes to form a phagosome.
Exocytosis is a cellular process, a form of active transport use to transport materials OUT of a cell.
The answer to this is number 1. Aquaporins. This integral membrane is responsible for providing the needed channels so that water can be transferred easily. You can just imagine how hard it would be when these channels do not exist in order to serve as the passageway of water between the different cells of living things.
There are times when there are some small solutes along the membrane. This integral membrane can be found in a lot of living things. There are some studies that show that each aquaporin molecule that can be found within the membrane has a pore. The 4th option may be considered too but aquaporins are considered the correct term.
