Phenol red broth base is the media that is used to grow most organisms and a large amount of a potentially fermentable sugar.
For the purpose of microorganism differentiation, phenol red broth base is advised to ascertain the fermentation response of carbohydrates.
Gram negative bacilli can be recognised with it, particularly Enterobacteriaceae. It includes one carbohydrate, a Durham tube, peptone, and phenol red (a pH indicator) (glucose, lactose, or sucrose).
When a carbohydrate is utilised by an organism, an acid byproduct is produced, which causes the media to turn yellow. If the organism can use the peptone but not the carbohydrate, ammonia is produced as a byproduct, which raises the pH of the medium and colours it fuchsia.
A gas byproduct could be created once the organism is able to utilise the carbohydrate. If so, the Durham tube will become caught by an air bubble. Gas will not be created and no air bubble will emerge if the organism is unable to use the carbohydrates .

A non scientific question is a question which cannot be proved to be true as no experiment or no data can be gathered from it. Why are roses the best flowers? is an example of nonscientific question. The answer of this question is subjective and it brings no scientific data. Scientific question on the other hand is a question that may lead to a hypothesis and help us in answering (or figuring out) the reason for some observation.
Answer:
C. causes cell lysis
Explanation:
The slow release of the bacteriophage progeny from a bacterial host cell causes bacterial cell lysis and further kills the host cell which is the bacteria, this results to the liberation of progeny viruses which then infect new bacterial cells.
Only a type of bacteriophage called the filamentous bacteriophage reproduces without killing the bacterial host cell. The filamentous phages infect majorly gram negative bacteria.
Answer: The systems regulate the house, the same way our body system helps regulate our body. If it wasn’t for the electrical system, plumbing system, heating, and cooling system the house wouldn’t be regulated or able to live in. Just like if our bodies isn’t being regulated, we can't live.
I hope this could help you! ^^
