Answer:
Aquaporins
Explanation:
Aquaporins are the channel proteins that is present in the membrane of the cell which allow water to cross the membrane very quickly. This aquaporins play an important roles in plant cells, red blood cells, and certain parts of the kidney where this protein minimize the amount of water lost as urine. Without this protein, the diffusion of water across the cell membrane is not possible very quickly.
Answer:
The answer (Image 1) is attached. Since the options weren't provided, I've attached the image of the options, too.
Explanation:
The plasma membrane is composed of phospholipids, a special form of lipids with a hydrophilic head and hydrophobic tail. According to the fluid mosaic model, the hydrophilic heads are positioned towards the outside where they freely interact with the extracellular matrix and cytosol. Whereas, the hydrophobic tails are positioned towards the inside so they aren't exposed to water.
Liposomes are lipid bases particles used for drug and vector delivery. The picture shows a typical liposome.
In the current case, for water to move both outside and inside, hydrophilic heads should be present inside as well as outside the tails.
Answer:
The correct option is A. The cell is sitting in a hypertonic solution.
Explanation:
A hypertonic solution is a solution in which there are more number of solutes present in the solution than inside the cell. The solutes then tend to pass into the cell through diffusion from the solution.
As it can be seen in the diagram, the concentration of salt is more in the solution i.e 40%. Hence, the salt from the solution enters into the cell by diffusion and has a concentration of 10% inside the cell which shows the cell to be placed in a hypertonic environment.
Answer:
what are the conditions
I know that hot water helps and i know that moving the tea bags helps
Explanation:
If the object doesn’t contain carbon. All living things contain carbon in some way. Except monoxide, dioxide, carbides, and carbonates
