"Water quality" may include the amounts of dissolved oxygen
and the levels of algal growth, pollutants which may be present and the pH level. Water quality effects also which types of organisms can
survive in a body of water.
Shellfish require a high level
of dissolved oxygen and their abundance is an indication of good water quality. Shellfish are sensitive to changes in the ecosystem and they cannot easily escape changes in the water quality. These are one of the reasons why shellfish are good indicators of water quality.
Depends upon the temperature of neighboring elements
<u>Explanation:</u>
- The equations of heat flow in solids does not depend on which way flows up.
- The direction of heat flow in a small element within a solid depends on the temperature of its neighboring elements.
- It is due to the fact that only neighboring element can decide that heat can pass from the system or into the system.
- Heat normally flows from hot substance to cold substance.
Channel proteins that form a narrow passageway in gap junctions are known as <span>connexons
</span><span>Connexons are assemblies of six proteins that form a pore or a narrow passageway between the cytoplasm of two adjacent cells.
These passageways allow the bidirectional passage of iron and signals between the cells. </span>
