I have a quiz tomorrow on these topics: Prokaryotes vs Eukaryotes
What is a plant?
Stems, Roots, Leaves
Flowering Plants
Seeds and Fruits

I could really use some help

c-reactive protein (crp) is an acute phase protein belonging to pentraxin family of proteins, whose levels increases 1000-fold or more in concentration in blood during the occurrence of an injury, inflammation or tissue death.

i am going to guess that it is co2.
