Answer: A.The population of pink katydids will decrease.
B.The population of green katydids will decrease.
Explanation:
The two statements describe what will eventually happen to the population of the katydids are that:
• A.The population of pink katydids will decrease.
• The population of green katydids will decrease.
This is because from the information given, since birds started feeding on the katydids, this will result in the reduction in the number of katydids. Hence, the decrease in both the pink and the green katydids.
Answer:
<u>Gastroesophageal reflux</u> is a chronic condition in which acidic stomach contents leak into the esophagus, causing pain and damaging the esophagus.
Explanation:
The Esophagus is a part of the digestive tract, which communicates the pharynx with the stomach. Under normal conditions, the gastric or intestinal contents do not pass into the esophagus, since there is a lower esophageal sphincter (IAS) that acts as a valve and prevents the backflow of food. Gastroesophageal reflux (GERD) occurs when stomach contents are returned to the esophagus and causes heartburn (also known as gastric reflux), that is, it occurs when a muscle at the end of the esophagus does not close properly. This allows the stomach contents to return, or reflux, to the esophagus and irritate the mucosa and produce different symptoms and complications.
