Answer:
Water molecules are polar and form strong hydrogen bonds.

Properties like high surface tension and boiling point are unique to water due to water's polar molecules. This allows water to form very strong hydrogen bonds and give it some different abilities.
Answer: habitat preference
Explanation:
One of the driving factors for ecological speciation that does not allow interbreeding between the members of a species is habitat preference. Some members of a species have a different preference for habitat than others in terms of habitat preference. They reside and do not interbreed in various environments. These two populations of a species live in diverse environments acquire genetic differences over generations and interbreed only with members of their own populations.
