Which solubility graph correctly depicts the increase of solubility associated with an increase of temperature of the solution?

Solubility is defined as the capability of the solute to dissolve in the solvent. Solubility depends upon the temperature. In the given graph, solubility of many salts is increases with increase in temperature but solubility of sodium chloride is relatively constant i.e. slightly effect of temperature.

In aqueous solution, sodium chloride completely exist as  and  ions. Thus, there is no external force required for its dissociation.

Hence, sodium chloride shows the least increase in solubility with increase in temperature.

Option (B) is correct answer.

answer; i believe that the correct answer is(d) nondisjunction during meiosis;

if the hares very faster than they are now, and thus the lynx's hunting success rate drops because it will be harder to catch them, the rate that will change will be the pray-rate. the pray-rate will change because more hares will be able to survive, thus more individuals for reproduction, so the end result will be increasing population of hares.

the predator-rate will remain pretty much the same because there will be more than enough pray, but the hunting success rate is stagnant.
