Answer:

sour, corrosive

Explanation:

An acid is a substance that donates hydrogen ions. Because of this, in an acidic solution  there are more hydrogen ions than hydroxide ions. This means the more acidic a food is, the more hydrogen ions are available to trigger the sour taste receptors. A base is a substance that accepts hydrogen ions.

Assume that the left ventricle of a child's heart has an EDV=90mL, and ESV=60mL, and a cardiac output of 2,400 mL/min. His SV is
Sliva [168]

Answer:

SV = 30 ml/ beat.

HR = 80.

Explanation:

The formula to calculate SV is as follows:

SV = EDV- ESV.

Here EDV = 90ml (end diastolic volume), ESV = 60ml (end systolic volume) ans SV is stroke volume.

SV = 90-60

SV = 30ml/beat.

The formula to calculate HR is as follows:

HR = CO/SV

Here, HR is heart rate, CO is cardiac output = 2,400 ml/min and SV is stroke volume = 30ml/beat

HR = 2,400/30

HR = 80.

Thus, the SV is 30ml/best and HR is 80.
