Answer: Capillaries
Explanation:
Capillaries are the thin-walled blood vessels that connect arteries to veins. They are essential for the distribution of oxygenated blood from arteries to the tissues and carrying back deoxygenated blood towards the heart. Capillaries, which are about 120 angstroms in diameter, also facilitate the exchange of nutrients, oxygen, and waste products between the blood and cells.
The thin-walled blood vessels that connect arteries to veins are called capillaries. Capillaries are the smallest and thinnest of the blood vessels in the body and they serve to distribute oxygenated blood from arteries to the tissues. After oxygen is used by these tissues, the deoxygenated blood is then carried back towards the heart by veins.
Because capillaries are so thin, they allow the exchange of nutrients, oxygen, and waste products between blood and the cells. With a diameter of about 5 to 10 micrometers, they are just about 120 angstroms, which is wide enough for blood cells to pass in single file. Capillaries are a crucial part of the circulatory system and are found throughout the body, making up a large part of the body's total blood vessels.

The correct answer is Active transport.
The transportation of molecules against the concentration gradient from the area of its low concentration to high concentration is called Active Transport.The molecular size of vitamins are large so, it is not easy to transport them against the concentration gradient without the help of energy. This energy is in the form of ATP.
Thus, liver uses Active Transport to move vitamins from one area to another area.

B. Your mass is too low.
C. Mars is a larger planet than Earth.
D. Mars is a long distance away.
The correct answer is option D. Mars is a long distance away.
According to the universal law of gravitation, the effect of the force of gravity decreases as the distance increases. The gravitation force is inversely proportional to the radius or the distance. So, the gravitational force exhibited by the Mars is not experienced by us due to the large distance.
