Answer:

A concentrated buffer can neutralize more added acid or base than a dilute buffer, because it contains more acid/conjugate base. However, any buffer will lose its effectiveness if too much strong acid or base is added.

ankoles [38]

Answer:

Procedural memory

Explanation:

Isabel has to recall the information about using a manual stick shift. For this reason, she is using long-term, explicit, declarative and episodic memory system.

Human memory system can be broadly classified as: sensory memory, short-term memory and long-term memory.

Long-term memory is used to recall information. If the information are about facts, events and experiences then explicit, declarative and episodic memory helps to recall all information. This will help Isabel to recall all information about driving a car with a manual stick shift and she will be able to drive her sister's car.

1. on the trace above
ser-zykov [4K]

Answer:

1. when there is cardiovascular disease.

2. High blood pressure increases the likelihood of suffering a stroke, a heart attack, heart failure, kidney disease or premature death.

3. The mitral valve opens.

Explanation:

1. High blood pressure is a common condition in which the force exerted by blood against the walls of the arteries over the course of time is high enough to cause you health problems such as heart disease. After the first rise of pressure caused cardiac ejection volume, one notch occurs with a second ascent product of the reflection of the pulse wave. In younger individuals, with elastic arteries, said wave occurs in diastole, so does not influence the peak systolic pressure. By contrast, with advancing age and the stiffness of large vessels, the reflected wave is transmitted prior to the aorta (systole) so as to increase the peak central PAS.

2. The pressure increases progressively the pressure of the blood flowing through the arteries. As a result, you can submit the following: Arteries damaged and narrowed. High blood pressure can damage the cells of the inner lining of the arteries.

3. When the pressure in the left ventricle falls below the pressure of the left atrium, the mitral valve opens, and the left ventricle fills with blood that had been accumulating in the left atrium.
