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. Hexadecimal is a base-16 number system. It is a different method of representing numbers than the base-10 system we use in every day practice. In base-10, we count in multiples of 10 before adding another digit.For example, 8 - 9 - 10 - 11 - 12... and 98 - 99 - 100 - 101 - 102....n base-16, or the hexadecimal number system, each digit can have sixteen values instead of ten. The values of a hexadecimal digit can be: 0, 1, 2, 3, 4, 5, 6, 7, 8, 9, A, B, C, D, E, F. Therefore, the number 12 (in the common base-10 format) would be represented as C in hexadecimal notation.
