If by external sex, meaning gender, then yes, because X and X makes a female because that is the female genes but X and Y is the male gene so adding the Y would change the external sex.
Answer:
Gut microflora is a combination of many different kinds of bacteria. Out of these, Lactobacillus bacteria, specifically, <em>Lactobacillius acidophilus</em> and <em>Lactobacillus bulgaricus </em>primarily help in the digestion of the milk sugar lactose. Probiotic bacteria in the gut microbiota, primarily, Lactobacillus and Bifidobacterium help in the synthesis of vitamins.
Explanation:
Gut Microbiota:
Gut microbiota are the microorganisms that live inside the gastrointestinal tract and aid in various body functions. Also called commensal flora, many of these help in digestion and biosyntheisis of vitamins.
- Lactobacillus species are a predominant component of gut microbiota. Lactobacillus produces an enzyme called lactase that breaks down lactose sugar in milk.
- Complex sugars in vegetables and fruits are broken down, mostly, by gut microbiota.
- Probiotic bacteria, Lactobacillus and Bifidobacterium species aid the biosynthesis of various vitamins and nutrients such as:
- Vitamin K and most of the water‐soluble B vitamins, such as biotin, cobalamin, folates, nicotinic acid, panthotenic acid, pyridoxine, riboflavin, and thiamine.

<span>Lactic Acid Fermentation and Alcoholic Fermentation. Lactic Acid fermentation produces lactic acid, and alcoholic fermentation produces alcohol and carbon dioxide.Lactic acid fermentation has 2 ATP. Oxygen is required for the process to occur-Aerobic means. No oxygen is required for the process to occur-Anaerobic means. The ferment sugar which produces ethanol, methanol, and only a little ATP.</span>
