Below is an image of a lizard resting on top of water.  Given the properties/characteristics of water, choose which option (A/B/C) below is most accurate and explain why you made that choice.   A.  The lizard is light weighed and weighs less than the water, so it does not fall through the density of water molecules it is standing upon. B.  Water is a polar molecule and therefore cohesive. The water molecules are held together by hydrogen bonds.  The hydrogen bonds ‘stretch’ allowing the lizard to remain on top of the water. C.  The polar water molecules adhere to each other so that the weight of the insect is not great enough for the molecules to break apart the covalent bonds. The lizard can remain on top of the water.
