Most oxygen in the blood is transported:

1.5% is carried in the plasma as a dissolved gas

98.5% O2 carried in the blood is bound to the protein hemoglobin in red blood cells. A fully saturated oxyhemoglobin has four O2 molecules attached.

Explanation:

label a cell membrane

label b cytoplasm

label c ribosomes

label d dna

the membrane forms the outside of the cell

cytoplasm is the liquid within

ribosomes are the components within that distribute rna

the dna is the genetic make-up

hydrogen is a compound or a single element and a element is a pure substence that cannot be separated into simpler subtances

clorine is a compound its a chemical substance that forms when two or more different elements combine

so both hydrogen and clorine are compounds
