Asalt dissolved in water forms a. anions and cations b. only anions c. only cations d. neutral atoms

The correct answer is option A, that is, anions and cations.

Explanation:

Water is considered as the common solvent as it can dissolve more components in comparison to any other liquid. It does this as the molecules of water exhibits an electric charge, which is adequately strong to disturb the molecular bonds of the components it dissolves. For example, sodium chloride or table salt dissolved in water.  

When one puts salt in water, the ions of sodium and chloride get separate, that is, they get separated into anions and cations. Chlorine ions carry a negative charge (anion) and sodium ions exhibiting a positive charge. When one dissolves salt in water, the positive ions move towards the negative ends of the molecules of water, and the negative ions mediate towards the other end. In this manner, each molecule of water disturbs the lattice composition, and the outcome is a solution of free ions scattered in water.  

. moose and then wolf populations grow larger during cycle peaks—with enough wolves, all moose are eaten, leading to extinction for both.

Explanation:

At the peak of the cycle, Mosses which are vascular plants grow more increasing their population size this will in turn increase the number of wolves because food is available in abundance at the peak of the cycle.

Shortly after the peak the wolves will continue to feed on the mosses even when the population size of the plant is no longer increasing until there are no more food, the wolves who depend on plant will have to starve, some that are outcompete will die, some of the wolves will start feeding on themselves for survival, while others migrate the territory in search of food this will lead to extinction of the animals.
