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.

olga55 [171]

Answer:

A. Atmosphere

Explanation:

Atmosphere would be most immediately affected by a decrease in sunlight because sunlight is responsible for the photosynthesis in plants. if sunlight decreases, the photosynthesis reaction is also decreases in plants and less carbondioxide gas is used by the plant from atmosphere for making their food so we can say that atmosphere is greatly affected by the decrease in sunlight.

Why was it important to allow all the investigation materials to assume room temperature before beginning the experiment?
hram777 [196]

Answer:

The temperature is kept at room temperature and mostly preferred to be constant, so that the temperature does't be a variable factor effecting the accuracy of experiment.

Temperature is kept constant to take it as a control factor, so that experimental results are not effected by such outside factors. Such control variables are important in experiments as they minimize the influences from outside.

What approximate percentage of lymphocytes is seen at age 4?
mr_godi [17]

Answer:

Blood is composed of several types of cells:

  • <u>RED BLOOD CELLS</u>: They are the oxygen carriers of the body i.e. they pick  up the oxygen as the blood goes through the lungs & release of oxygen to cells.Also known as erthrocytes
  • <u>WHITE BLOOD CELLS</u>:  also known as leukocytes.They are the soldiers of the body.Aims at fighting against the infections ( caused by bacteria & virus)
  • <u>PLATELETS</u> : helps in the blood clot in response to any wound or injury

There are five types of white blood cells & approx %age they made up in blood are:

•Neutrophils (55% to 70%)

•Band neutrophils (0% to 3%)

•Lymphocytes (20% to 40%)

•Monocytes (2% to 8%)

•Eosinophils (1% to 4%)

•Basophils (0.5% to 1%)

When children are more than 4 year old they  have higher  % age of lymphocytes than the adults do.

If a cell is placed inside a solution that has a higher concentration of solute than on the inside of the cell, what can be said
sergiy2304 [10]
Since the cell is hypotonic compared to the solution surrounding it which is hypertonic, the water will move out of the cell in an effort to reach equilibrium between the two.
