Answer:
The activity factor was modified. Ambulating indicates that the person is active. Even small activities require energy. So, people who can walk around and aren’t bedridden expend more calories than people who need to be on bedrest all day. Also, when the stress factor was changed to severe infection, the caloric requirement increased. This increase is probably because the immune system requires more energy to fight off the infection

The branch of biology dealing with interactions along organisms and between organisms and their environment is called Ecology, I believe.
Answer:
B. interconnected
Explanation:
All the systems in our bodies (humans are indeed animals) are connected with each other to create a functional being. The blood flows throughout the body, providing nutrients; the bones support the structure and protect the heart and lungs. They work together.
Why not A: The systems are all completely necessary. There's nothing extraneous in our bodies, because extraneous stuff takes up energy, and our biology is incredibly economical.
Why not B: They're not interchangeable. How would you like your bones to turn to blood? Uh-huh.
Why not D: They interact with each other consistently, so they're not separate or segregated.

Answer:
Foods are ingested by the mouth where they are chewed by the teeth and savored by the taste buds present in the tongue. In the mouth, saliva breaks down food into substances that are easier to digest. Subsequently, the pharynx allows food to be swallowed and it pushes the food into the esophagus, the contractions of the esophageal muscle allow the movement of the food through the esophagus and to the stomach where the food is mixed with the juices and are mostly digested. In the stomach nutrients are absorbed. There are particles that are not absorb and they pass to the intestine where other nutrients are transported to the blood, then pass to the large interstinum where there is water absorption and stool formation that are expelled through the rectum.
