Answer:
The hypothesis is ''the higher population of algae in a pond has a direct relation on the higher concentration of nutrients in the pond''
Explanation:
''The higher population of algae in a pond has a direct relation on the higher concentration of nutrients in the pond''. The population of algae increases vigorously when there is high concentration of nutrients such as nitrogen and phosphorus in the pond. So if there are two ponds having different concentration of nutrients so the population of algae will be higher in that pond where nutrients are present in high amount.

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.
