Answer:A) The ocean is hypertonic to the erythrocytes.
Explanation:cells shrink when placed in an hypertonic solution.
This shrinkage occurs does to the movement of water out of the cell and through the cell membrane.this phenomenon is called plasmolysis.
The movement of water out of this cell occurs through osmosis.osmosis is the movement of water from a region of high concentration of solute to a region of low concentration of solute, through a semi-permeable membrane.
In this case,sea water has a higher concentration of solute (hypertonic) and the blood cells has a lower concentration(hypotonic) .the cell membrane serves as the semi-permeable membrane and and a result water moves out of the cell
just know about super power
what is renewable power¿¿
1.It is a universal solvent.
2Pure water is transparent, colourless and odourless.
3.Pure water is a poor conductor of electricity.
4.Water in a pure form has a neutral ph i.e 7 which means it is neither acidic nor basic.
Answer:
B. The molecules are evenly spread out
Explanation:
salt is completely soluble in water. Na+ will be surrounded by OH- and Cl- will be surrounded by H+
Cell Hypothesis is one of the fundamental standards of science. Credit for the plan of this hypothesis is given to German researchers Theodor Schwann, Matthias Schleiden, and Rudolph Virchow.
Cells need nutrition in order to get the required elements. Which specific foods provide specific elements, and what do those elements do in the cell?
...
The major macromolecules are:
carbohydrates and lipids - made of carbon, hydrogen, and water.
proteins - provide nitrogen and sulfur.
nucleic acids - provide phosphate.
