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.

Let us assign the dominant allele (that of brown hair) letter R
while
We assign the recessive
allele (that of white hair) letter r
We then note down the
Hardy-Weinburg equation p2 + 2pq + q2 = 1
Brown fur population (p2
+ 2pq) = 64% = 0.64
White fur population (q2) = 36% = 0.36
Then we also remember that the frequencies of both allele
add up to 1 (p + q = 1);
Therefore q = ü.36
= 0.6
P = 1 – q = 1 – 0.6 = 0.4
The heterozygous population will be 2*0.6*0.4 = 0.48 = 48%
Homozygous domain population will therefore be (64% - 48%) =
16%
Answer:
true
Explanation:
A Tsunami can reach very fast speeds. Waves can travel across the Pacific Ocean in less than one day Though locally generated tsunamis can reach coastlines in just minutes. Japan for example.
Recessive allele because dominant allele hinders organisms from reproducing which means that there is lesser of it with dominant allele
