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.
Why is the hexadecimal system often used to manipulate color in digital media? colour in digital media is commonly stored 24 bits per pixel; 8 each for red, blue and green. 6 hexadecimal digits encode 24 bits exactly, separating red, blue and green into â¦ groups of 2 digits.
