1 | P a g e Molecules - A 1.1 Water Learning objectives and guiding questions: “What are the challenges and opportunities of water as a habitat?” Comparing the adaptations to physical properties of animals: The ringed seal (Pusa hispida) lives almost exclusively in the cold seas and on the ice of the Arctic Basin. The black-throated loon (Gavia arctica) also lives in the cold Arctic, spending time in the water, on land and in the air. These two animals have physical and behavioral adaptations to the physical properties of both air and water in respect to viscosity, buoyancy, thermal conductivity, and specific heat capacity.

Scientists believe that water sources on Earth are a consequence of asteroid collision, which have taken place in the first few 100 million years after Earth’s formation. These asteriods most...
