water is an essential substance for living organisms. describe three characteristics of water that make it so important for life.

1.the oxygen is released from plants to provide us with oxygen

2.water can dissolve such a wide veriety of molecules

3.your body is made up with 80% of water

Water is able to absorb heat and retain this energy for a long period of time. Thus, living things warm up and cool off slowly due to this feature of all the water they contain. Water molecules are attracted to each other and are held together by hydrogen bonds. Due to the large number of these very weak bonds between individual water molecules, water has a great interconnectivity of individual molecules. When taken in large quantities, these bonds allow water to support the weight of a water spider as well as to flow as a cohesive unit or to bead up on a freshly waxed automobile hood. Water molecules are also attracted to other polar molecules. The attraction between different substances is called adhesion.

Explanation:

because the light is a great source of energy for the plants to survive. (i hope this )

the cladogram shown here shows similarities and differences among several classes of vertebrates. anatomically, the four have limb structure as their common ancestor. we might separate the mammals from the other three classes because they a) divergent; do not lay eggs b) identical; are warm-blooded c) varied; a four chambered heart d) homologous; have mammary glands
