Answer:
Taking more samples from different parts of an acre.
Explanation:
Validity and accuracy of the data is crucial for any serious research. In this particular case, the most accurate data would be obtained if earthworms would be counted on the whole acre. Of course, this would consume lot of time, people, money etc. That's why methods for estimation are used. Estimation best works with large number of samples. Since one acre equals over 4000 square meters, taking only five samples from such a big area is simply not enough for obtaining valid data.
One of the possible ways to improve estimation is to take more samples per acre while avoiding taking adjacent samples because it could be possible that number of earthworms in one part of an acre is increased (or decreased) for any reason, which would lead us to wrong conclusion.
Hemoglobin is contained in red blood cells,which efficiently carries oxygen from the lungs to the tissues of the body. It also helps in the transportation of carbon dioxide and hydrogen ions back to the lungs.

Answer:
<h2> located in the same plane</h2>
Explanation:
- Such types of muscles and tendons that play an important role in the stabilization of the shoulder are called rotator cuff muscle.
- These muscles are responsible for the different types of motion and simply called a different range of motion.
- Muscles like scapulohumeral muscles, infraspinatus muscle and some others are grouped as rotator muscle.
- These muscles are involved in the movement of the shoulder and also stabilize the joints of the shoulder for the movement and during the movement.
- When the humeral head is centered within the cavity of the glenoidal then the rotator cuff muscle should be on the same plane.
