The correct answer is: Heartburn often results when the gastroesophageal sphincter fails to close properly.
The gastroesophageal sphincter is a muscle located at the bottom of the esophagus that has to be relaxed in order to allow food to flow down into the stomach. After it contracts (tightens), the food and the stomach acid can’t flow back up into the esophagus.
When the gastroesophageal sphincter fails to close properly acid reflux occurs and causes the heartburn.
After looking at the graph represented above, I think I habe recognized the correct answer, <span> so the statement which would best predict the population in generation 4 is being shown in the first option : </span><span>The nonresistant aphid would become extinct. As you can see from the tree pictures, nonresistant ones gradually become lower and lower and in the last one it has the same weak position as resistant in the first picture, then I would say that nonresistant will expire soon.
Hope that helps!</span>
