Answer:
Hemoglobin.pulmonary artery.
Explanation:
1. about hemoglobin.Hemoglobin is the protein inside red blood cells. It carries oxygen.
2. about pulmonary artery.The pulmonary artery is a big artery that comes from the heart. It splits into two main branches, and brings blood from the heart to the lungs. At the lungs, the blood picks up oxygen and drops off carbon dioxide. The blood then returns to the heart through the pulmonary veins.
3. There exist a concentration difference of carbon dioxide and oxygen inside the alveoli and capillaries due to which the diffusion of the two gases takes place. The carbon dioxide moves from the blood to the alveoli sac and the oxygen moves from the sacs to the blood.

Answer:
The correct option is D. analogous
Explanation:
We speak of an analogy when one structure is similar to another or has the same function, but whose embryonic development and its origin or ancestor is not common, they are different, in other words, they are analogous structures if they fulfill functions or acquire similar characteristics starting from the same medium, without requiring them to have the same evolutionary origin (they may or may not be similar structurally and embryologically).
