Infant development researchers released a study recently that compared two groups of babies: those who were fed breast-milk during their first six months of life and those who were fed formula during the same period. The study's results showed that the group of infants fed breast-milk weighed significantly more on average at one year of age than did the group fed formula. The researchers concluded that a breast-milk diet leads to greater weight gain among babies than a formula diet. Which of the following would cast the most doubt on the researchers' conclusion? A. The mothers of infants in the breast-milk-fed group weighed significantly more on average than the mothers of babies in the formula-fed group. B. Many of the infants in the formula-fed group at one year of age weighed more than the average weight of the breast-milk fed group at one year of age. C. The average weight of the infants in the breast-milk-fed group was significantly greater than the average weight of the babies in the formula-fed group when the study began. D. In controlled laboratory studies, a hormone found in breast-milk has been linked to increased weight gain in baby mice. E. The average amounts of breast-milk and formula consumed by the two groups of infants over the course of the study were approximately equal.

The primary function of the respiratory system is to supply the blood with oxygen in order for the blood to deliver oxygen to all parts of the body. the respiratory system does this through breathing. when we breathe, we inhale oxygen and exhale carbon dioxide. this exchange of gases is the respiratory system's means of getting oxygen to the blood.respiration is achieved through the mouth, nose, trachea, lungs, and diaphragm. oxygen enters the respiratory system through the mouth and the nose. the oxygen then passes through the larynx (where speech sounds are produced) and the trachea which is a tube that enters the chest cavity. in the chest cavity, the trachea splits into two smaller tubes called the bronchi. each bronchus then divides again forming the bronchial tubes. the bronchial tubes lead directly into the lungs where they divide into many smaller tubes which connect to tiny sacs called alveoli. the average adult's lungs contain about 600 million of these spongy, air-filled sacs that are surrounded by capillaries. the inhaled oxygen passes into the alveoli and then diffuses through the capillaries into the arterial blood. meanwhile, the waste-rich blood from the veins releases its carbon dioxide into the alveoli. the carbon dioxide follows the same path out of the lungs when you exhale.the diaphragm's job is to pump the carbon dioxide out of the lungs and pull the oxygen into the lungs. the diaphragm is a sheet of muscles that lies across the bottom of the chest cavity. as the diaphragm contracts and relaxes, breathing takes place. when the diaphragm contracts, oxygen is pulled into the lungs. when the diaphragm relaxes, carbon dioxide is pumped out of the lungs. write one paragraph (at least 6 sentences) describing the path of oxygen through the respiratory system. also include why this "order of operations" is the way it is!
