The chemical element is formed of only one type of atom, has a unique and unique chemical symbol and can be identified by its atomic number.

Currently about 115 chemical elements are officially recognized, with properties quite different from each other and others that resemble each other. Therefore, the elements were organized in ascending order of atomic number, forming a set that is known as the Periodic Table.

The theory of vitalism has been rejected by present day scientist described by to visit them describe what scientists not think
Furkat [3]

According to the theory of vitalism all the living substances are special and are distinct from the non-living substances, that is, they comprise a unique entity within themselves. This soul or entity distinguishes them from the non-living components.  

However, the theory was rejected when urea was taken out successfully from a non-living matter by Wohler, proving the fact that the biological constituents can be extracted from a non-living source. The modern scientists now believe that the living things are just more composite than the non-living substances.

Answer:

B. MacConkey is both a differential and a selective medium.

Explanation:

Selective media contain the ingredients that allows for the growing of specific microbes while inhibiting the others.

For example MacConkey media facilitate the growth of gram negative bacteria and inhibit the growth of gram positive bacteria. That why E. coli and P. mirabilis grew on the media because these are gram negative and S. saprophyticus does not grew being gram positive.

Differential media allow to differentiate between selected microbes by visual observation.

For Example MacConkey media differentiate between organisms that can ferment lactose to the organisms that can't ferment it. That why E. coli appeared pink on the media because it can ferment lactose while P. mirabilis appears colorless because it usually cannot ferment lactose.
