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.

Hospolipid bilayer, with some protein, is what makes the cell membrane selectively permeable.
Answer:
Hypotenuse = 7.07 units.
Explanation:
The sides of the right angle triangle are the opposite and adjacent side; which are both equal in this case.
Given the following data;
Opposite = 5 units
Adjacent = 5 units
To find the hypotenuse, we would use the Pythagorean theorem given by the formula;
Hypotenuse² = opposite² + adjacent²
Hypotenuse² = 5² + 5²
Hypotenuse² = 25 + 25
Hypotenuse² = 50
Hypotenuse = √50
Taking the square root of both sides, we have;
Hypotenuse = 7.07 units.

Answer:
Species B is the predator of species A.
Explanation:
The graph illustrates a predator prey relationship.
A predator can be described as an organism that eats other organisms while the prey is the animal that is killed and eaten by the predator. Both the predators and the preys usually co-exist in the same ecosystem. The relationship between the predator and the prey affect the population of the organisms in all ecosystem; it determines the mortality of preys and the birth of new predators.
