The cavity of the body immediately inferior to the diaphragm is the cavity.

The cavity of the body immediately inferior to the diaphragm is the Abdominal cavity.

Explanation:

The body cavity is divided into upper thoracic cavity ad lower abdominal cavity. Both these cavities are separated by a membranous diaphragm. Above the diaphragm lies the Heart and a pair of lungs. Below the diaphragm in the abdominal cavity the following organs are present:

Liver, gall bladder, spleen, stomach, pancreas, small intestine, large intestine, and a pair of kidneys. The largest organ in the abdominal cavity is liver.

In the digestive system, rectum is a part of pelvic cavity which is below the abdominal cavity.

All the organs present inside are lined by a layer of peritoneum called visceral peritoneum whereas the abdominal wall is lined by parietal peritoneum.

the two answers are a, the population of birds with large beaks will increase on the island, and c, the trait for large beaks will be passed on to future generations through natural selection. the reason for that is because if the birds that have beaks developed for eating small seeds lose all of their food, they will go hungry and eventually starve because they physically cannot eat the large seeds, therefore making the population of large beaked birds higher. also, if the trait of large beaks are dominant on the island over small beaks, then over time the large beaked birds will reproduce more and more, while the smaller beaked birds will reproduce less and less because they can't survive with the food provided. that leads to the trait of small beaks disappearing and the trait of large beaks taking over the island.
