I think it’s respiratory but I’m not sure
While Louis Pasteur was the one that procured the germ theory of disease that explains that diseases are caused by microorganisms, the first researcher that provided direct experimental data to support the said theory is Robert Koch.
Robert Koch developed a criteria for the causality of disease from microorganisms called the Koch's postulates. The Koch's postulates indicate that:
(1) The bacteria must be present in every case of the disease
(2) <span>The bacteria must be extracted and isolated from the host with the disease and should be directly visualized and/or grown in culture
(3) There must be a healthy experimental host that will reproduce the disease once the isolated bacteria is injected
(4) The bacteria should be recoverable from the previously healthy host

The sled with a rough metal bottom would take more force to move over ice, because the rough surface would increase friction and the force needed.
Cardiovascular diseases
Metabolic syndrome is a
combination or cluster of metabolic risk factors in a single individual. However,
the metabolic risk factors include hypertension, insulin resistance, stroke,
heart diseases and cholesterol abnormalities. Thus, the clustering of all these
risk factors is specific to cardiovascular diseases.
The reported mass will be too high because the initially recorded mass will include both water and impurities and the final mass will without both components. The difference will be larger so the amount of water reported would be higher.
