While fishing, you make the following observations: a. Water spiders appear to be able walk on the surface of the water. b. Flat
rocks may be made to skip across the water. Which of the following properties of water can explain these observations? A) Water is an excellent solvent. B) Water molecules are heavy. C) Water molecules are cohesive. D) Water molecules are polar. E) Both B and C
The observations point to the <em>cohesive qualities and surface tension of water.</em>
<u>Cohesion refers to the attraction of molecules for other molecules of the same kind, and water molecules have strong cohesive forces thanks to their ability to form hydrogen bonds with one another.</u>
Water is polar and a great solvent but these are not related to the observations stated in the question.
Option (b) Both are polymers of D-glucose but cellulose is connected by ( beta 1-4 ) glycosidic linkage whereas glycogen is connected by ( alpha1-4) glycosidic linkage....
