The Andean people's blood has more ___, which holds oxygen from the lungs onto the red blood cells.chlorophyllrhodopsinhemoglobincarotene

The correct answer is hemoglobin.

Explanation

Hemoglobin is a protein found in red blood cells that is responsible for transporting oxygen from the lungs to the tissues throughout the body. In mountainous regions like the Andes, where the air has lower oxygen pressure, the Andean people have adapted by having a higher concentration of hemoglobin. This adaptation allows for more efficient oxygen delivery in environments where oxygen availability is limited, which is crucial for survival and physical performance at high altitudes.

1. Chlorophyll: This is the green pigment in plants that is involved in photosynthesis and does not have any role in oxygen transport in the human body.

2. Rhodopsin: This is a light-sensitive receptor protein involved in the phototransduction process in the retina of the eye, unrelated to blood oxygen transport.

3. Carotene: A type of pigment found in plants that can be converted into vitamin A in the body, again, unrelated to oxygen transport in blood.

In conclusion, hemoglobin is essential for enhancing oxygen transport and is particularly beneficial for populations living in high-altitude environments like the Andes.
