A substance that can dissolve other substances
Pure substances are either elements or compounds. Elements can NOT be separated into other types of matter (physically or chemically). Therefore, elements are pure substances. Ex: Hydrogen gas is a pure substance, as it is made up of only Hydrogen atoms or molecules.
Answer:
Hematocrit is a blood test that can identify anemia, dehydration and even heart disease. Generally, if the hematocrit values are too low, it can indicate the presence of anemia. If the hematocrit value is too high, the number of red blood cells in your blood is very high.
Explanation:
Hematocrit is a blood test that measures the percentage of the volume of all blood that is made up of red blood cells. If the hematocrit value increases, it is usually a sign that the body is not oxygenating well, and it compensates for it by increasing the number of red blood cells. If the hematocrit value decreases, it indicates anemia, the red blood cells or erythrocytes are cells capable of transporting oxygen to the tissues; Therefore, when they are reduced, a deficit of oxygen supply to the cells occurs, causing various symptoms. The heart tries to bring more blood supply to the tissues with the intention of increasing its oxygenation, for this reason the heart rate increases, producing tachycardias that are perceived as palpitations.
