All of the following contributes to turbulent blood flow except third and fourth heart sounds.
<h3><u>
Explanation:</u></h3>
The blood flow in human body is always described to be laminar. Some conditions cause the high flow when there is an ascending aorta. This causes the laminar flow of blood into turbulent. When this occurs the flow of the blood will not be smooth and linear.
When the kinetic energy in the fluid flow increases the turbulent flow of blood occurs. Both the magnitude and the direction of the flow changes in this type of blood flow. These are caused by the irregularities in the vessel walls, flow rates to ne higher and opening of the valves of the heart.
Answer:
Thirty patients with acne volunteer to be treated with either a medicinal lotion

a clinical trial.-B.
The yellow powder and the blue liquid producing a clear green liquid after mixing shows that these two substances are soluble.
The soluble substances are those which are completely mixed in each other producing a new solution. The insoluble substances are those, which do not mix together with each other, and remain separated. The miscible substances are those liquids which completely mix with each other forming a homogeneous mixture, while the immiscible substances are those liquids that do not form a homogeneous mixture when mixed.
Hence, the answer is 'soluble'.
