MacConkey Agar contains crystal violet which binds to gram positive bacteria, preventing them from growing. The media turns yellow in response to the production of acid when lactose is fermented. Which two terms best describe this media

The media describes Selective  and Differential.

Explanation:

Given - MacConkey Agar contains crystal violet which binds to gram positive bacteria, preventing them from growing. The media turns yellow in response to the production of acid when lactose is fermented.

To find - Which two terms best describe this media ?

Proof -

The media describes Selective  and Differential.

Reason -

MacConkey is a selective and differential media.

This media is used to selectively isolate gram-negative bacteria from other bacteria and differentiate them on the basis of lactose fermentation.

Lactose fermenters turn red or pink on MacConkey agar, and non-fermenters do not change color.

that would be called plucking : )

explanation:

''plucking, also referred to as quarrying, is a glacial phenomenon that is responsible for the erosion and transportation of individual pieces of bedrock, especially large "joint blocks". as a glacier moves down a valley, friction causes the basal ice of the glacier to melt and infiltrate joints (cracks) in the bedrock."

the answer is c because it is most logical.
