Which experiments led to changes to the original cell theory? A. Experiments that showed that blood cells transport gases, waste, and nutrients throughout the body. B. Experiments that showed that all cells are similar in how they metabolize and in their composition. C. Experiments that transplanted synthetic chromosomes into bacterial cells to create a new species. D. Experiments that established the existence of single-celled organisms and microbes.

The experiment that would lead to changes to the original cell theory is the third experiment or the option C. The cell was first discovered by Robert Hooke in 1665 and the cell theory which states that All living things are made up of cells was collaboration of the works of Hooke, Leeuwenhoek, and others. 


D: Experiments that established the existence of single-celled organisms and microbes  There are a lot of created theories in which biologists engaged themselves to explain such phenomenon that occurred thousands of years ago, and experts say such study is hard to replicate, the start of prokaryote cells. Prokaryotes were said to be the first organisms that existed and were able to exhibit photosynthesis that produced oxygen that spread across the atmosphere. Hence, consider the Theory of Spontaneous formation of organic moleculeswhich suggests that the early earth had less to none oxygen. Thus, the atmosphere was abundant with the gases, CO2 and N2 with some other small amounts of H2, H2S, and CO. Hence, in Stanley Miller’s experiment when electrical sparks or “lightning” came in contact with these gases, the newly formed mixtures of CH4, NH3, and H2 were catalyzed. With these newly formed gases in interaction with H2O came the first synthesized some amino acids that compromised the earliest organic molecules which evolved to macromolecules, to be organelles of a cell. Which in the latter macromolecules are in today, maybe have been before the early nucleic acids (able to replicate) or proteins of these early cells.
