Which characteristic of the ringed seal (Pusa hispida) is a consequence of the thermal conductivity of water?
Correct Answer: \( \boxed{\mathbf{C}} \)
Water has a high thermal conductivity, causing body heat to be lost rapidly. A thick layer of blubber acts as an insulator, reducing heat loss and helping the ringed seal maintain its body temperature in cold water.
Which symbol indicates the polarity of the oxygen atom in the water molecule?
Which of the following is a consequence of the adhesive properties of water?
Correct Answer: \( \boxed{\mathbf{B}} \)
Adhesion is the attraction between water molecules and other surfaces. This property enables capillary action, allowing water to cling to the walls of narrow spaces and move through soil and plant tissues against gravity.
