Answer: c. they are very productive agriculturally

Explanation:

The laterite soil is reddish to yellow in color. It is typically found in hot and wet tropical areas. The soil exhibit a lower concentration of nitrogen, potassium, lime, phosphorus and magnesia. But soil contains high concentration of oxides of iron, manganese and titanium. It is not suitable for agriculture as the soil lacks essential elements required for the growth of crops like nitrogen, potassium and phosphorus. The soil is suitable for making bricks.

Ksivusya [100]

The organ system interacts with each other to maintain the normal functioning of the body. The composition of blood changes due to this interaction. The change is the blood going out from the lungs is deoxygenated and the one coming to the lungs is oxygenated.

<h3>What is the interaction of the respiratory and circulatory systems?</h3>

The respiratory system involves inhalation of oxygen and using this to release energy and exhalation of carbon dioxide.

The circulatory system is comprised of the heart and blood vessels. The heart pumps blood to different body organs through these blood vessels.

The transfer of oxygen is done with the help of blood. During this transfer, the composition of blood changes from being oxygenated means having oxygen to deoxygenated means having carbon dioxide.

Thus, in this way, the interaction changes the composition of blood.

Answer:

D, The white blood cells of sick people may not be able to efficiently handle the weakened or dead form of the pathogen.

Explanation:

Vaccinations are essentially just weak diseases we use to create antibodies so the body can protect itself from the full disease. If it sees it once, it can defend itself, is the theory. This is choice D.

Why not A: The weakened form will be attacked by the immune system, but maybe not enough, because the person is so sick that the immune system is busy elsewhere.
Why not B: The medication is not what combines with the vaccine to cause problems. It is the body being overworked.
Why not C: The digestive system isn't the issue. You don't eat diseases.
