Answer:
Miasma theory was replaced because John Snow collected data that showed that germs cause disease.
Explanation:
The theory of miasma was proposed in the past when some scientists —like doctors Thomas Sydenham and Giovanni Maria Lancisi— thought that disease was the product of emanations originated by the decomposition of organic matter. This theory was based on the fact that diseases predominated in places with poor hygienic conditions.
John Snow, an english physician, was one of the main contributors to the <u>microbial theory of disease</u>. In 1854, while a cholera epidemic was occurring, he collected data and organized it statistically and then concluded that the disease was caused by germs present in drinking water. This <u>data was contrary to the miasma theory, which would eventually be displaced by the microbial theory of the disease</u>.

Answer:
C. "Using the sodium-potassium pump involves the hydrolysis of ATP and the
release of Nat to the outside of the cell."
Explanation:
The use of a sodium-potassium pump is a form of active transport, not diffusion. It also requires energy because the pump moves ions against their concentration gradient (low to high), unlike diffusion.
