Advantages:
>No cables needed.
>Multiple channels available.
>Wide bandwidth.
Disadvantages:
>Line-of-sight will be disrupted if any obstacle, such as new buildings, are in the way.
>Signal absorption by the atmosphere. Microwaves suffer from attenuation due to atmospheric conditions.
>Towers are expensive to build.

Initially address, Gram-negative in light of the fact that the precious stone violet restrains the development of gram-positive.
Second question, Fermentation: the blend of carb lactose, bile salts, and pH turn it unbiased red since they are enteric and age lactose
Third, we would see the development since it is gram negative microbes.
Fourth
1. coliform microbes (pink settlements in light of the fact that the pH is brought down and they are lactose fermenters)
2. Looseness of the bowels typhoid, and paratyphoid bacilli (tan and straightforward provinces since they are non-fermenters)
Observation is the answer
hope this helps
