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.

46 chromosomes. 23 pairs. 23 chromosomes come from the egg (from the mother) and 23 come from the sperm (from the father). Haploid (containing one set of chromosomes) sperm and egg fuse to form a diploid (containing two sets of chromosomes, one from each parent) zygote.
Answer:
The three steps of cellular respiration are 1 glycolysis 2 TCA cycle 3 Oxidative phosphorylation.
Explanation:
Glycolysis During glycolysis glucose is used and pyruvate is made.2 molecules of ATP is made in Glycolysis .
TCA cycle During TCA cycle Acetyl CoA is used and oxaloacetate is formed.2 molecules of GTP is produced during TCA cycle.2 molecules of GTP is equivalent to 2 molecules of ATP.
Oxidative phosphorylation During this process NADH,FADH2 are used and water is formed.34 molecules of ATP is generated during oxidative phosphorylation.
