densk [106]

Answer:the following can be done to allow more NaCl to dissolve;

1.) heating the mixture.

2.) Addition of extra water to the solution.

Explanation:

When sodium chloride is dissolved in water, the polar water molecules are able to work their way in between the individual ions in the lattice. The water molecules surround the negative chloride ions and positive sodium ions and pull them away into the solution. This process is called dissociation. Now when the solution is heated, the rate of the dissociation between the two molecules increases leading to more dissolution of NaCl. Also in the absence of heating, more Water molecules can be added to the solution to decrease it's saturation thereby favouring the dissolution of more NaCl.

Evidence for coordinated stasis is found in ____.
KonstantinChe [14]

The correct answer is option (A) the fossil record.

Coordinated stasis refers to the stasis or the no evolutionary changes in the organisms for millions of years, which is followed by extinction and formation of the new species.

Fossil records have the evidence of ecological and evolutionary stability in the species over a long period of geological time scale separated by intervals of abrupt change. The best example of this being the animals of the Middle Devonian Hamilton group. Thus, fossil record is the only source of record showing this long period of stasis and separated by periods of abrupt changes in the species due to environmental pressures.
