Answer: Oligodynamic and unaffected by antimicrobial resistance
Explanation:
Silver is one of the most affected effective antimicrobial which is so effective that the microbes die when being exposed to the silver.
It is used in case of wound dressing, and it is used to coat medical devices . It is used as an external application such as on the skin and while dressing.

Answer:
Liquid and with a higher osmotic pressure
Explanation:
Remember that a cell that is surrounded by an environment with a higher osmotic pressure, will produce that the cell get some water outside to make some dilution to the salt concentration that surrounds the protozoan.
