Like all batteries, eventually it gets depleted and needs to be replaced; this can be expected to happen after 5-10 years, depending on system usage. CMOS checksum error (and similar messages) or the system clock being reset are classic signs of the battery having been depleted. The BIOS settings contain several system-critical values.
In order to grow, yeast need glucose (C 6 H 12 O 6) or sucrose (table sugar, C 12 H 22 O 11), water (H 2 O) and warm temperatures. As yeast digest sugar, they turn into alcohol. In the process they give off carbon dioxide (CO 2) gas. The alcohol dissolves in the water and the gas escapes into the air. Yeast is used to make bread.
Tube 1: glucose plus yeast Tube2: sucrose plus... show more Sucrose (table sugar) is a dissacharide composed of glucose and fructose. Glycogen is a polysaccharide composed of many glucose subunits. Which of the following fermenetation tubes would you expect to produce the greatest gas volume over a 1-hour period? why? Tube 1: glucose plus yeast Tube2: sucrose plus yeast Tube 3: glycogen plus yeast.
