Water is a unique molecule with unique bonding properties. Part A: Explain why and how the polar covalent bonds found in water molecules are responoble for water's ability to dissolve many substances, particularly ionic compounds such as salt.
Part B: Identify the solvent and the solute in the solution that has been created in part A from the dissolving of salt in water.

Examine the two squirrel populations in the accompanying figure. the populations are separated by a geographic barrier. if after a long period of time the two species are no longer separated, what evidence is needed to determine if speciation has occurred? the figure shows two populations of squirrels separated by a geographic barrier. examine the two squirrel populations in the accompanying figure. the populations are separated by a geographic barrier. if after a long period of time the two species are no longer separated, what evidence is needed to determine if speciation has occurred? the figure shows two populations of squirrels separated by a geographic barrier. polyploidy is creating new species. the two populations are not interbreeding freely. hybrid offspring of the two populations begin to appear. one species will increase into a population size twice as large as the other species.
