Answer:
All are methods to separate mixtures
Explanation:
<em>A mixture consists of 2 or more substances that are mixed physically but not chemically. Hence, mixtures can be separated by any physical separation means which include but not limited to filtration, distillation, sieving, magnetization, and evaporation.</em>
Filtration is usually used to separate suspended particles in a liquid using a membrane of a filter paper. Distillation is used to separate miscible liquids with varying boiling points by evaporating and condensing them back at their respective boiling points. Sieving is used to separate mixtures with varying particle sizes of individual components.
Magnetization is usually used to separate mixtures with, at least, one component with magnetic property. Evaporation is used to separate dissolved solids from liquids.
<u>Hence, all the methods listed are used to separate mixtures.</u>
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.
