Answer:
The progenitor of the platelets is called a megakaryocyte.
Explanation:
Platelets are blood structures, which participate in the process of blood clotting. They are also known as thrombocytes.
The process of platelet formation is called thrombopoiesis, and it consists of
- <em>Formation of megakaryoblasts from the hemocyte, a hematopoietic precursor cell. </em>
- <em>Megakaryoblasts produce </em><em>megakaryocytes</em><em>.
</em>
- <em>Megakaryocytes are precursors to platelet</em><em>s.
</em>
Each megakaryocyte must fragment to form the thrombocytes or platelets.
Misapplied constancy scaling theory is one of several theories that explains the Ponzo illusion. According to the theory, the pictorial depth information in the background will rescale the size of objects in such a manner that those that appear further are perceived larger
Answer:
The mitral valve has fewer flaps than the right atrioventricular valve:
<em>a) True </em>
Explanation:
The mitral valve is a bicuspid valve, which means it has two flaps; whereas, the right atrioventricular valve is a tricuspid valve and so has three flaps.
These two heart valves link the atrium with the ventricles. The mitral valve is located on the left side of the heart, while the tricuspid valve is on the right side.
Answer:
The training regimens of these athletes are, however, not uniform. Power training can indeed be static but is sometimes described as dynamic involving ... distance runners have a larger left ventricular mass than non-athletic control subjects, ... form of strength training, heart rate, cardiac output, and blood pressure increase.
