Answer:
Pylorus
Explanation:
The stomach is a J-shaped organ which is a part of the digestive system. The digestive system on one end is attached to the oesophagus and on the end to the small intestine.
The pylorus structure of the stomach is composed of thick muscles which help to mix or agitating the food in the stomach and controls the movement of the food to the duodenum which is the first part of the small intestine. The movement is controlled by the ring of muscles in the pylorus called pyloric sphincter.
Thus, Pylorus is the correct answer.
 
        
             
        
        
        
Answer:
Evolution, mutation, and adaptation
Explanation:
Since different organisms adapt to different environments and receive different mutations, they adapt differently and slowly change. That is why there are different species of birds, just look at the galapagos islands, there are thousands of species of finches that changed to survive on each island. The same could be said for every organism since the early organisms that we evolved from were widespread, some evolved differently than others, leading to different fish, different lizards, different early mammals, and so on. That is why humans look different than dogs or cats, we evolved best to our environment so we could survive.
