A blood sample is spun in a test tube until the red cells settle to the bottom, and the percentage of RBCs is calculated: hematocrit.
<h3>What is Hematocrit?</h3>
- The hematocrit, also known by several other names, is the volume percentage (vol%) of red blood cells (RBCs) in blood, measured as a part of a blood test.
- The measurement depends on the amount and size of red blood cells. It's normally 40.7–50.3% for males and 36.1–44.3% for females.
- It is one of the components of a person's complete blood count, along with hemoglobin concentration, white blood cell count, and platelet count.
- Because the purpose of red blood cells is to transport oxygen from the lungs to body tissues, the hematocrit—the red blood corpuscle volume percentage—of a blood sample can be used to determine its ability to deliver oxygen.
- Too high or too low hematocrit levels can indicate a blood disease, dehydration, or other medical conditions.
- An abnormally low hematocrit may suggest anemia, a decrease in the total amount of red blood cells, while an abnormally high hematocrit is named polycythemia. Both are potentially life-threatening disorders.
Therefore, a blood sample is spun in a test tube until the red cells settle to the bottom, and the percentage of RBCs is calculated: hematocrit.

Hope that helped! I wasn't 100% sure but I hope this is right. If it's wrong, please tell me! Have a good day!
Answer:
They can change over time because when you combine two different species together they can turn into a new and different specie. This shows that artificial selection can provide evidence that species can change over time.
Answer: B. They contain genetic information
Explanation: The role of nucleic acids is to store the genetic information (DNA) and to decode that information into proteins (RNA). DNA is also the form in which genetic information is passed from one generation to the next.
