Question

Which three statements are true of blood flowing through a capillary at the location marked by the green circle?

O oxygen diffuses from the water into the blood.
O dissolved oxygen in the blood is highest at this point.
O dissolved oxygen in the blood is lowest at this point.
O no oxygen diffusion occurs at this point.
O the water surrounding the blood has a high concentration of oxygen.
O the water surrounding the blood has a low concentration of oxygen.

Answer 1

Oxygen diffuses from water into the blood, increasing the concentration of dissolved oxygen in the blood. The location marked by the green circle in the capillary has the highest concentration of dissolved oxygen in the blood. The water surrounding the blood at this location has a low concentration of oxygen.

Step-by-step explanation:

Oxygen diffuses from the water into the blood at the location marked by the green circle in the capillary. This is because the concentration of oxygen molecules is higher in the water than in the blood. As a result, oxygen molecules move from the area of higher concentration (water) to the area of lower concentration (blood) by the process of diffusion.

The dissolved oxygen in the blood is highest at this point in the capillary. As oxygen diffuses from the water into the blood, the concentration of dissolved oxygen in the blood increases. Therefore, the highest concentration of dissolved oxygen in the blood is found at the location marked by the green circle in the capillary.

The water surrounding the blood at the location marked by the green circle has a low concentration of oxygen. This is because oxygen molecules diffuse from the water into the blood, reducing the concentration of oxygen in the water surrounding the blood.
