What type of agar medium is used to demonstrate bacterial motility? A) Semi-solid agar B) Nutrient agar C) Blood agar D) Lactose agar
Understand the Problem
The question is asking which type of agar medium is specifically used to demonstrate bacterial motility among the given options. This relates to microbiology and the properties of different agar types.
Answer
Semi-solid agar
The final answer is Semi-solid agar
Answer for screen readers
The final answer is Semi-solid agar
More Information
Semi-solid agar medium, which contains a lower agar concentration (typically around 0.5%), is used to demonstrate bacterial motility. This medium allows bacteria to move through it, revealing their motility characteristics.
Tips
A common mistake is using solid agar, which does not support movement, or choosing nutrient-rich media over ones specifically intended for motility demonstration.
