A patient is very dehydrated. This dehydration caused a loss of water in the cells and left behind high levels of salt inside the cells. You want to give the patient an IV that will allow the patient to absorb the water into their cells rather than it being filtered and peed out. Which of the following solutions would drive water into the cells of this dehydrated individual due to a concentration gradient difference?

Use this information to answer the next four questions. Investigators determined the effects of noise stress on heart rate.  Rats (n=6) were prepared with indwelling arterial catheters so that heart rate could be monitored.  Average heart rate for a 10 minute period was recorded for each rat under quiet conditions.  The rats were then exposed to continuous loud noise and the average heart rate was again recorded for 10 minutes. The data are presented below.   Group 1: Quiet Heart Rate (beats per minute) Group 2: Noise Heart Rate (beats per minutes) Rat 1 385 450 Rat 2 360 440 Rat 3 375 460 Rat 4 350 400 Rat 5 400 480 Rat 6 370 430
