What do you mean by fermentation?
The metabolic process of fermentation alters the chemical composition of organic substrates through the action of enzymes. The process of generating energy from carbohydrates without the presence of oxygen is expressly stated as such in biochemistry. If the action of microbes produces the intended alteration to a food or beverage, it may more broadly refer to any process utilized in food production. Zymology, or fermentation science, is a field of study. The primary mechanism by which bacteria manufacture adenosine triphosphate is fermentation, which involves the anaerobic degradation of organic molecules (ATP).

Answer:
Vein
Explanation:
Veins are the ones that keep you alive because blood goes inside the vein
Nucleic acids do that.............
Answer: 1/4
Explanation:
Firstly, in order for both parents to be type A and have children with type o blood, their blood types must both be Ao. Since o is a recessive blood type, a punnett square shows there is a 25% chance any child of theirs will have type o blood. If neither parent is color blind and they have a son who is, it implies that the mother is a carrier of colorblindness and has the genotype XᴮXᵇ. If you do a punnett square of the not colorblind father (XᴮY) and the mother, it shows that a daughter would have a 0% chance of being colorblind. Therefore colorblindess is irrelevent, since there is no possibility of the daughter not having normal color vision. In conclusion, there's a 25% chance she will have type o blood and not be colorblind, since the other 75% chance would be having type A blood and not being colorblind.
Answer:
Mechanical barriers — which include the skin , mucous membranes , and fluids such as tears and urine — physically block pathogens from entering the body. Chemical barriers — such as enzymes in sweat , saliva , and semen — kill pathogens on body surfaces.
