<span>When the lid for a vat
of wine is slightly open, the yeast inside can continue to perform alcoholic
fermentation because the carbon dioxide produced by the yeast during
fermentation will act as a blanket over the wine. Nevertheless, the air around the fermenter
must be still and enough carbon dioxide should be produced to continue
alcoholic fermentation. However, at some point, carbon dioxide will fall and
can no longer protect the wine. This is the right time to get your wine covered
before it will be vulnerable to undesirable microorganisms. </span>
Therefore, open fermentation
is good in the early stages of fermentation because yeast need oxygen to synthesize sterols and assimilate
fatty acids to ensure the nutrients it needs to multiply and ferment the 70% of the sugar from the fruit. Furthermore,
the yeast is responsible in decomposing sugar from the grapes into alcohol and
carbon dioxide.
<span>Reticulocytes are immature red blood cells.
Red blood cells that haven't fully developed, yet.
When our bodies lose a large amount of blood,
we rapidly produce reticulocytes,
so that our bodies can quickly replenish their red blood supplies.
And obviously, when we donate blood, we lose blood.</span>
Answer:
Insulin helps the cells absorb glucose, reducing blood sugar and providing the cells with glucose for energy. When blood sugar levels are too low, the pancreas releases glucagon. Glucagon instructs the liver to release stored glucose, which causes blood sugar to rise.
Hope this helps!
