The modern atomic model is called electron cloud model because each orbital around the nucleus of the atom resembles a fuzzy cloud around the nucleus
The answer is:
the change in red blood cell volume is principally due to the movement of WATER.
These ones it helps to draw. you have four carbons and each one must have 4 covalent bonds coming off of it, but the double bond will act as a 2 covalent bonds between carbon atoms rather than 1. You should get C4H8. Alternatively the alkene formula can be used (alkenes are molecules with a C to C double bond) which states CnH2n will be the Molecular formula where n is the number of carbons.
Well, dissolved carbon is basically carbon, and carbon and other atmospheric gases dissolve in water. So that would most likely lead to the answer being oceans and lakes.
