1) pathogen enters body and releases chemoattractants

2) a phagocyte/macrophage is attracted by these chemicals

3) the phagocyte engulfs the pathogen using its pseudopodia

4) the membranes of both organisms fuse forming a phagosome

5) lysosomers in the phogocyte fuse with the phagosome, forming a phagolysosome

6) these enzymes digest the pahogen (hydrolyse the bonds)

7) the antigens of the pathogen are placed on the surface of the phagocyte making an APC (antigen presenting cell)

Semisolid media such as MIO are used to determine motility. Another such medium such is SIM (sulfide, indole, motility) medium.

Flauer [41]

Answer:

Explanation:

In this specific scenario, seeing since both of the mediums are differential, the bacteria can grow on either of them, therefore either of them would be a good choice. A differential media allows the researcher to visually distinguish which species have the specific biochemical process. Which in this case both options have the ability to allow bacteria to grow which is what is needed.
