A single-cell organism or plant that feeds on simple sugars that are converted into alcohol and carbon dioxide through fermentation. Yeast is used as an activator to start various reactions necessary to produce alchoholic beverages and baked goods. In alcoholic beverages, it is a key enabler for the fermentation of grains resulting in the creation of alcohol and carbonation common in wine, beer, and other beverages.
I am having pregnancy symptoms (nausea, tender nipples) but I got a BFN (big fat negative) on my home pregnancy test. Those could be pregnancy symptoms, and you may indeed be pregnant, especially if you had intercourse during your fertile time and took that pregnancy test before you were really late..
Pregnancy lasts about 40 weeks, and has three phases or stages; the 1st, 2nd, 3rd trimesters. Early symptoms of pregnancy may include constipation, headache, heartburn, extreme tiredness, and upset stomach. Symptoms vary from week to week during pregnancy. A pregnancy test can easily confirm if you are pregnant.
