Stress can cause a virus to switch from the lysogenic cycle to the lytic cycle.
The ATP is the adenosine triphosphate. The ATP molecule has the three phosphate molecules attached with the adenosine. The ADP is the adenosine diphosphate. It has two phosphate groups. The number of phosphate molecules is responsible for the amount of energy in bonds. Hence the ATP molecule has the three phosphate group hence it has more stored energy as compared to the ADP molecule which has two phosphate group.
Charles Darwin noticed that among the same species there were variations in traits based upon geographical location. These changes may have evolved from climate differences, predator/prey relationships and food sources. This particular experiment was intended to duplicate natural selection by demonstrating the concepts with artificial selection. The result was that over time, new traits could be bred for. Although there may be more than one correct answer here, the best answer is the first; desirable traits can be selected and bred in offspring.
Evaporation and condensation can be used to purify water because it allows for the dirt and other chemicals that are harmful to be taken out of the water and leave behind a much cleaner and purified water, almost like filtering it naturally.
