Answer:

B. differential

Explanation:

The culture medium is a chemical preparation that has the necessary nutrients for microorganisms of a given biological sample to multiply, allowing its study, identification and analysis. The main components of a culture medium are sources of carbon, energy (sugars), nitrogen, phosphorus and minerals.

There are several types of culture medium, among them we can mention the differential culture medium, which is the type of medium that is being used in the experiment shown in the question above. The differential culture medium allows the distinction between various genera and species of similar microorganisms. This distinction is possible because this type of culture medium has substances that allow for a presumptive differentiation, evidenced by the color change or the morphology of the colonies.

antoniya [11.8K]

Answer:

Volcanic gases. (Ans A)

Explanation:

Ocean water is salty because of the presence of dissolved salt. When water contact with a rock it starts weathering processes and this process starts to dissolve the soluble elements such as sodium out of the rock.

In volcanic gases, lots of chlorine ions are present in the atmosphere, these ions easily dissolve with water and produce the large flux of chloride that splashes into the oceans. So, the most common source of chloride ions in ocean waters comes from the volcanic explosions.
