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>.

Bumek [7]

Answer:

The correct answer is "The common ancestor of coyotes and domestic dogs is more recent than the common ancestor of red foxes and domestic dogs".

Explanation:

One of the fastest way to known if two species have recent common ancestors is to look if they have common taxonomic ranks. In this case we can conclude that The common ancestor of coyotes and domestic dogs is more recent than the common ancestor of red foxes and domestic dogs, because the coyotes (Canis latrans) and the domestic dogs (Canis familiaris) share the same genus (Canis). The common ancestor of foxes and domestic dogs is more ancient because red foxes (Vulpes fulva) do not share the same genus has domestic dogs (Canis familiaris).

ivann1987 [24]

Answer:

Statement B is false.

Explanation:

PKA and PKG is both have binding domains to attach with nucleoside monophosphate and help in modulating these enzymes that explains that PKA is more related to the PKG than PKC at the level of amino acid.

At the level of  polypeptide chain level PKG has single polypeptide chain whereas in PKA modulatory domains are located on different poly peptide chain. Both are activated by the nucluoside triphosphate, more precisely PKA by cAMP and PKG is by cGMP respectively, whereas PKC is activated by DAG or Ca or both depending on the isofom.

Thus, the correct answer is - option B.
