In the 1800s, a popular belief known as vitalism stated that life processes could not be explained by the laws of physics and chemistry, and were instead dictated by an independent life force. which discovery most likely caused scientists to revise this hypothesis regarding the origin of life on earth?

a. that inorganic compounds existed within live organisms
b. that organic compounds could be synthesized in a laboratory
c. that rna could serve as a template to synthesize dna
d. that self-replicating molecules existed inside cells

a. that inorganic compounds existed within live organisms

Explanation:

Living organisms in general are made up of organic compounds but also contain chemical elements in the form of inorganic compounds such as vitamin D. In addition, living organisms are composed of a greater percentage of the chemical compound water.

This premise made scientists believe that they have chemical compounds comply with the laws of physics and chemistry

relative dating involves things like higher layers are most recent than rocks lower in the sequence. this can be extended to the known sequence of fossils. rocks containing rabbit fossils are later than those containing dinosaur fossils.  

absolute dating methods mainly use radioactive elements that have known rates of decay and produce recognizable products. for example potassium 40 decays to produce argon. once a rock has solidified the argon is trapped. by measuring the argon and potassium0 you can get an accurate number for the age.  

some other methods are good for archaeological ages. dendrochronology involves recognizing the sequence of tree rings. the orientation of magnetized particles in baked clay can be used to date a fire.
