The Carbohydrate Fermentation test uses Phenol Red Broth to test for the fermentation of different sugars. It is one of the fermentation tests, others include the Methyl Red test and the Voges-Proskauer test.
The main reason why we use hexadecimal numbers is because it is much easier to express binary number representations in hex than it is in any other base number system. Computers do not actually work in hex (donât laugh, beginning students do ask that question). Lets look at an example, using a byte.
Hexadecimal numbers are used in computing for the convenience of humans since the computer really only understands pure binary. Hex is much more compact than binary since it iâ¦s based on 16 (the fourth power of 2) instead of 2. Pure binary numbers based on 2 can quickly become unwieldy to write.
