An isotonic environment is when the concentration of solutes and solvent (water) are the same.
<span>When a cell is hypertonic, it shrinks because the concentration of solvent/solutes are unequal. If the inside of the cell has less solutes and more solvent, the solvent inside (water) will diffuse out the cell because of the concept of "going doing the concentration gradient". Anything will travel from a high concentration to a low concentration. In the case of hypertonic, water will move out the cell and causes it to shrink. </span>
<span>Hypotonic is when the cell is enlarged by water moving inside. So a hypotonic cell will look like it's big and expanded. Water goes where there is less concentration of it. You can also think about it from another perspective. Water always go where there is more solutes. So if the solute concentration like sodium or sugar or ect. is greater inside a cell or a piece of potato, then water will go there (since if there is a high concentration of solutes, then there is low concentration of solvent). </span>
Molality can be expressed by moles of solute over
kilograms of solvent. The question asks the molality of 0.25m NaCl. 0.25m NaCl
is equal to 0.25 moles of NaCl over 1 kg of water.
Explanation:
The largest water reservoir is the ocean, containing 97.3% of all water on Earth. This is of course salt water and is toxic unless specially treated to remove the salt. The next biggest reservoir are glaciers and polar ice containing just over 2% of the available water.
Answer:
Protons, neutrons, electrons..
Explanation:
Protons and neutrons consist of quarks which are stuck together by tiny things called gluons.
Hope this helps! :)
Answer:
People show more interest in personal broadcasting.
Explanation:
The art of oration (speaking) is being replaced by personal broadcasting mean now people used webcam or camcorder for creating its own content and transmit it to other people through internet. Personal broadcasting provides audio and video to the individual that make it more interesting as compared to oration. People show more interest in personal broadcasting as compared to oration so that's why oration is replaced by personal broadcasting.
