Answer:
The correct answer is: E) a bruit sound when auscultated with a stethoscope.
Explanation:
Mitral valve regurgitation is a condition in which the mitral valve - <em>responsible for the blood flow from the left atrium to the left ventricle </em>- doesn't close as tightly as it should, which can result in backward blood flow. If the condition worsens, this defect can lead to heart failure.
Mitral valve regurgitation may not have symptoms at first but, as the condition progresses, shortness of breath, fatigue, and palpitations can occur. When auscultated with a stethoscope, a bruit sound can be heard, which corresponds to the abnormal blood flow that is occurring.
Answer:
Dependent variable - increase in water level
Melting rate of ice - independent variable
Explanation:
Independent variables usually refers to the set of conditions, values or constraint used or adopted by an experimenter or researcher in other to cause a change in the measured variable also called the dependent variable.
The independent variable is therefore purposely used to depict or show changes in the dependent variable. The dependent variable is the measured variable whose behavior or output lies on the value of the independent variable.
In the scenario above, the dependent variable is the increase in water level,as it is what is being measured. And it is dependent on the Melting rate of ice, which is the independent variable.
That is change in water level in the cup, depends on the rate at which ice melts
