Bolivia

 

 

In October 2011 our little group: Sonia, Craig, Wendy and Richard visited Bolivia. We left Puno in Peru by bus to Cococabana in Bolivia. After the usual border form-filling and stamps, and a guided visit to the church in which the ‘Black Madonna’ resides, we boarded a cruise boat, a large catamaran, to Sun Island on the Bolivian side of the lake.

What everyone should know

Most of us already know that an atom is the smallest division of matter that can take part in a chemical reaction; that a molecule is a structure of two or more atoms; and that life on Earth is based on organic molecules: defined as those molecules that contain carbon, often in combination with hydrogen, oxygen and nitrogen as well as other elements like sodium, calcium, phosphorous and iron.  

Organic molecules can be very large indeed and come in all shapes and sizes. Like pieces in a jigsaw puzzle molecular shape is often important to an organic molecule's ability to bond to another to form elaborate and sometimes unique molecular structures.

All living things on Earth are comprised of cells and all cells are comprised of numerous molecular structures.
