Answer: it doesn't
Explanation: Why? The aorta is the largest artery in the body. The aorta begins at the top of the left ventricle the heart's muscular pumping chamber. The heart pumps blood from the left ventricle into the aorta through the aortic valve. Three leaflets on the aortic valve open and close with each heartbeat to allow one-way flow of blood. The aorta is a tube about a foot long and just over an inch in diameter. The aorta is divided into four sections:
• The ascending aorta rises up from the heart and is about 2 inches long. The coronary arteries branch off the ascending aorta to supply the heart with blood.
• The aortic arch curves over the heart, giving rise to branches that bring blood to the head, neck, and arms.
• The descending thoracic aorta travels down through the chest. Its small branches supply blood to the ribs and some chest structures.
• The abdominal aorta begins at the diaphragm, splitting to become the paired iliac arteries in the lower abdomen. Most of the major organs receive blood from branches of the abdominal aorta.
Like all arteries, the aorta's wall has several layers:
• The intima, the innermost layer, provides a smooth surface for blood to flow across.
• The media, the middle layer with muscle and elastic fibers, allows the aorta to expand and contract with each heartbeat.
• The adventitia, the outer layer, provides additional support and structure to the aorta.

Answer:
yes, over time pieces of an animals life cycle can change and adapt to help them survive in different environments that doesn't happen overnight. In a frogs life cycle they develop into a frog from an egg. frogs have adapted to become what they are today and if I where to make a prediction it would be that frogs at one point lived solely in water based on the way they grow and develop in there life cycle. having a life cycle means there's room for improvement and tiny adjustments can be Made as a defense mechanism that develops over the course of many froggy life cycles.
