Photoorganoheterotroph = use light, organic e- donor, carbon source. Chemolithoautotroph = use organic/inorganic mlcls for energy, inorganic e- donor, CO2 carbon source. Chemolithoheterotroph = use organic/inorganic mlcls for energy, inorganic e- donor, organic carbon source. Chemoorganoheterotoph = organic/inorganic energy source, organic e- donor, carbon source.
When plastic polymer technology was not much in use Waxed Paper or card board paper was used to wrap soaps, cookies and a host of other fragile items. Wax makes the paper stiff, water resistant and moisture proof. Wax is environmentally benign and non toxic to humans. Even now as a green measure we see fruit juice packs on such cardboard papers.
It is very likely that played a part . Chemical solvents such as acetone, alcohol (various alcohols, not just ethyl alcohol), toluene, xylene, turpentine, and benzene, are highly toxic and linked to lymphoma. Bob ross probably used a mixture of turpentine and something else as a paint thinner . He used to paint A LOT so given the fact that turpentine is carcenogenic inhaling its fumes will increase the odds of developing not only lung cancer , but also lymphoma and leukemia .
