According to the National Institute of Health, ventricular tachycardia is a fast, regular beating of the ventricles that may las

t for only a few seconds or for much longer. A few beats of ventricular tachycardia often doesn't cause problems. However, episodes that last for more than a few seconds can be dangerous. Ventricular tachycardia can turn into other, more serious arrhythmias, such as ventricular fibrillation.
Based on the passage above, how will prolonged ventricular tachycardia affect blood pressure?

1. It will increase blood pressure because the ventricles are contracting with more force.
2. It will increase blood pressure because the ventricles are filling with more blood between beats. (WRONGG!)
3. It will decrease blood pressure because there is a longer rest period beats of the ventricles
4. It will decrease blood pressure because the ventricles are filling with less blood between beats.

3 0

Answer:

1 makes the most sense

Explanation:

There is no way blood pressure will be decreased especially if your ventricles are erratically contracting for a long period of time. So 3 and 4 are out. And you said number 2 is wrong so my finally answer is 1.

Describe the buffer capacity of the acetic acid buffer solution in relation to the addition of both concentrated and dilute acid
frosja888 [35]

Answer:

The more concentrated acetic acid buffer has a better buffer capacity because requires more moles of acid or base to change the pH than a more diluted acetic acid buffer.

Explanation:

Buffer capacity is defined as the moles of an acid or base that are needed to change the pH of a buffer in 1 unit.

A more concentrated solution of acetic buffer contains more moles of the acid per liter of solution. A solution that contains more moles of the acetic ion or the acetic acid requires more moles of base or acid to change the pH, that means:

The more concentrated acetic acid buffer has a better buffer capacity because requires more moles of acid or base to change the pH than a more diluted acetic acid buffer.

Where Did the Water
vekshin1

Answer:

Axel: Much of the water is in the air around us.

Explanation:

When a puddle of water forms on the ground, it indicates that much of the ground around it is saturated with water and as such, the water would not readily soak into the ground. Also, since the puddle was found in a park, it is not likely that the water has gone into a stream, river, pond, lake, or ocean.

Since, the day was a sunny, it means that the heat from the sun has caused the evaporation of the water molecules. However, the water vapor molecules do not just immediately rise up to the atmosphere to form clouds nor do they cease to exist, rather it is dispersed in the air around the surroundings and beyond. Formation of clouds by water vapor takes days to happen.

Also, the water has not changed to fog either as they form usually at cooler temperatures.

AleksandrR [38]

Answer:

Supersaturated

Explanation:

The tea has absorbed and dissolved as much sugar as it could. If there is sugar left at the bottom, it means the solution is supersaturated because it can't absorb any more.
