Bright cherry red color is produced upon the addition of methyl red indicator to a culture of a Gram negative bacilli in MR-VP broth if the organism used the mixed acid pathway of fermentation.
What is MR-VP test?
- As part of the IMViC testing, Methyl Red (MR) and Voges-Proskauer (VP) broth is utilized as the medium in which both the Methyl Red and Voges-Prosakuer tests can be conducted.
- It is a straightforward broth made up of dextrose or glucose, buffers, and peptone.
- In the Methyl Red test, an infected tube of MR-VP broth is mixed with the pH indicator methyl red.
- The acids will overwhelm the buffers in the medium and create an acidic environment if the organism employs the mixed acid fermentation pathway and creates stable acidic end products.
- If acidic end products are present when methyl red is introduced, the methyl red will remain red.

Answer:
Kidney disorder is responsible for the disturbance occur in the balance of the body because kidney release certain harmones which are necessary for normal growth.
Explanation: There are three harmones releases by kidney i. e. erythropoietin, calcitriol, and renin. Erythropoietin is released by kidney when oxygen level is low in the tissue. It also controls the production of red blood cells. Calcitriol harmone controls the concentration of phosphorous and calcium in the blood. Renin is responsible for the increase in blood pressure when it is needed. So if the disorder of kidney occurs, imbalance occurs in the body.
