The pulmonary artery and its branches deliver blood rich in carbon dioxide (and lacking in oxygen) to the capillaries that surround the air sacs. The circulation of the blood through the lungs. The veins that return the oxygenated blood from the lungs to the left atrium of the heart.
The correct answer is The liquid at the top is the least dense
Explanation:
In this situation, liquids appear to be stacked or organized in different layers due to differences in density. This factor (density) is determined by the mass and volume of the liquid. For example, the density of water is 1 gram per milliliter, while the density of honey is 1.40 grams per milliliter, which makes honey to have a higher density.
Moreover, if liquids are in a container, the liquid or liquids with a lower density will go to the surface, while more dense liquids will sink. In this context, the liquid at the top is the least dense, while the liquid at the bottom is the densest.
I think its mandatory becuase at our age, we're going through hormonal changes and hella body changes.
