Answer:
b. The water molecule is polar.
Explanation:
Water molecules forming hydrogen bonds with one another. The partial negative charge on the O of one molecule can form a hydrogen bond with the partial positive charge on the hydrogens of other molecules. Water molecules are also attracted to other polar molecules and to ions.

<span>Each of the protein chains are conjugated to a nonprotein heme group.Hemoglobin is
the protein that's made of the four polypeptide chains. Each of these chains contains a heme group. Red blood cells are primary players in the oxygen hauling, and they wouldn't be able to do their job if it the weren't for a special molecule called the heme.</span>
The alkali metals in group l of the periodic table all have a single electron in the outermost shell. These metals form covalent bonds with for example the halogens, which have 7 electrons in their outer shell.
When the alkali metal halide, such as KCl is dissolved in water, it dissociates into ions. The K atom loses the single electron, and therefore has a positive charge. In turn, the chloride atom gains the electron and becomes the negatively charged chloride ion.
