What would happen if u place a cell in a container of water with high solute concentration?

Biology
1 answer:
Dmitriy789 [7]3 years ago
4 0

Answer:

Large quantities of water molecules constantly move across cell membranes by simple diffusion, often facilitated by movement through membrane proteins, including aquaporins. In general, net movement of water into or out of cells is negligible. For example, it has been estimated that an amount of water equivalent to roughly 100 times the volume of the cell diffuses across the red blood cell membrane every second; the cell doesn't lose or gain water because equal amounts go in and out. There are, however, many cases in which net flow of water occurs across cell membranes and sheets of cells. An example of great importance to you is the secretion of and absorption of water in your small intestine. In such situations, water still moves across membranes by simple diffusion, but the process is important enough to warrant a distinct name - osmosis.

Positive selection tests to see if the ______ of a T-lymphocyte can recognize and bind to an MHC molecule.
DENIUS [597]

Positive selection tests to see if the TCR of a T-lymphocyte can recognize and bind to an MHC molecule.

<h3>What is a T-lymphocyte?</h3>

A T-lymphocyte is a special type of immune cell that is generated inside the bone marrow.

The T-cell receptor (abbreviated as TCR) is a protein located on these immune T lymphocytes.
