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:
Pollination
Explanation: If you have ever seen bee movie, you know that pollen is the most essential ingredient to flowers, which is transported and spread by bee's. if there were no more bees, there would be no way to pollinate the flowers, causing them to wither and die. Fortunately, there are other pollinators, but bees are one of the most important.
Answer: C
Has about 95% water in It
<span>The experiment
performed by Francesco Redi supports the hypothesis that fly larvae only come
from adult flies based on his experiment design using a covered-meat and
non-covered meat. In addition, he also believed that maggots came from the fly
rather than from the rotten meat by using the same experiment design. </span>
Endothermic means it requires the absorption of heat or it is dependent on has the ablity to generate internal heat
exothermic means an animal that cna regulate its body temperature (usually by exchanging it with its surrounding environments)
so your answer is excothermic
