1 Which of the following is not a characteristic of water Water is composed of polar molecules Water is organic compound Water stabilizes temperature because it has a high specific heat Water has a ph of 7.0 because it is neither an acid or a base 2 Identify which of the following question is accurate Water molecules have no polarity therefore they are hydrophobic Water molecules exhibit polarity. Therefore substances attracted to water are hydrophilic The electrons in a water molecule spend most of their time around the hydrogen atom Water molecules can be polar or nonpolar; it depends on how the electron configure themselves 3 At a pH of 4 identify which of the following questions is accurate There are more hydrogen ions than hydroxide ions; the solution is basic The solution is neutral; neither basic or acidic The solution has more hydrogen ions than hydroxide ions; the solution is acidic 4 A RBC has a solute concentration of 530 miliequ, while a check cell is seen to have a solute concentration of 210 millieq. Which is an accurate representation of this phenomena? the rbc is hypertonic to the cheek cell; water will flow into the RBCcTrue the rbc is hypertonic to the cheek cell; water will flow out of the RBC the cheek cellis hypertonic to the RBC; water will not move in either direction
