Which two elements make up the most common compound in the human body

Water (H2O) is the most abundant chemical compound in the human body. Water is made up of one Oxygen atom, and two Hydrogen atoms.

Explanation:

The adult human body consists of 60% water, making it the most abundant chemical compound in the human body. A single water molecule is made up of two hydrogen atoms connected to a single oxygen atom, through polar covalent bonds.

According to The Journal of Biological Chemistry, the brain and heart consist of 73% water, while the lungs consist of 83% water! That's a lot of water for some of our vital organs!

Hope this helps! :)

what is the aerea shown

explanation:

the "power" of a lens is its resolution power, or its ability to distinguish between to closely located points. with the low power lens, it is likely you will see the rough form of the hay and maybe some movement of dots around the hay. however, when observed with the high power lens, the detailed features of the hay become visible and the microbes being grown are more clearly visible.

i hope this you
