Biology

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:

one characteristic that is shared by all is a soft body. many

of these invertebrate animals also have an outer shell to protect their

body. oysters, clams, snails, and mussels are all mollusks. so are octopuses, squids, and slugs. mollusks live on land and in freshwater.

characterization of nanoparticles is a critical step in nanomaterial production as it provides information of dimension, morphology, surface charge, distribution and degree of surface functionalization.
