How much water is tied up in *humans* on Earth? Things you might need to know to calculate this:
- population of Earth
- % composition of water in the average human
- average weight of the average human on Earth
- give your answer in US gallons. I know that science deals with SI units but not today.

Here is

Explanation:

Segun la ciencia estamos hecho del 15% o 20% de agua por humano,La manera más básica (aunque no necesariamente la más fácil o precisa) de medir la población es simplemente contando a todos. Esto se conoce como un censo y generalmente es realizado por los gobiernos. Antiguamente, las organizaciones religiosas realizaban censos, pero generalmente a nivel local o regional  

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.

one is through turgidity. this occurs before ground tissue ( collenchyma

and sclerenchyma cells) become well

developed to give structural support to the plant as it grows bigger. the xylem

tissue (composed of rigid tissue) of the young

plant render this support and also maintaining osmotic turgidity of the surrounding

plant cells.
