How did Louis Pasteur’s experiments lead to new scientific understandings of germs? Experiments with cooking food showed that disease-carrying germs in food could be killed when heated. Experiments with different magnification lenses showed that germs were real and could be observed. Experiments with animals showed that dominant genes could lead to risks of disease. Experiments with shallow dishes showed that groups of germs could be grown so they could be seen without microscopes.

Identify one disadvantage to each of the following models of electron configuration: -dot structures -arrow and line diagrams -written electron configurations type in your answer below. (answer) -dot structures do not show the distribution of electrons in orbitals and take up a lot of space. -arrow and line diagrams take up a lot of space and make it difficult to count electrons. -written configurations make it easy to lose count of electrons and do not show the distribution of electrons in orbitals.
