The correct answer is option D, that is, look for soil bacteria, which transforms nitrates into nitrogen gas.  

A microbial mediated procedure where nitrate is reduced and eventually generating molecular nitrogen via an array of intermediate gaseous nitrogen gaseous outcomes is known as denitrification.  

It is generally the withdrawal or the loss of nitrogen or nitrogen components, mainly the reduction of nitrites or nitrates by the bacteria in the soil, which usually leads to the escape of nitrogen into the atmosphere.

What is likely phenotypic ratio resulting from a dihybrid cross with alleles showing epistatic interactions?
Mashutka [201]

The answer is one (1) phenotype. This is because epistasis interaction of gene alleles involves the masking of one phenotype of an allele of a gene (at one or more loci) by the other.  Alternatively, the epistatic alleles may interact to cause a modification of a phenotype.

The bolus is liquefied in the ________ and it is now called chyme.
Strike441 [17]

Answer:

The options:

A) esophagus

B) stomach

C) small intestine

D) mouth

The CORRECT ANSWER IS B)

B) stomach

Explanation:

The digestive tract — often termed the gastrointestinal tract or alimentary canal — supplies the route via which foods passes through the body. In the course of this pathway, foods are digested into its constituents nutrients necessarily for absorption.

Digestion initially starts in the mouth, with enzymes in saliva dissolving carbohydrate (starch). In the course of chewing, the food is lubricated, a little bit of hear is used up, and less difficult to swallow and digest. The teeth and mouth aid conversion of each morsel of food to a bolus which flows right into the esophagus (“gullet”). In the course of chewing, taste buds stationed in the mouth gives pleasure to every mouthful — or to taste if not okay. Once the bolus is swallowed, it flows through the esophagus, it is kind of warmed and lubricated as it flows into the stomach.

Note:

The acidic condition of the STOMACH and the effect of gastric enzymes turns the bolus to CHYME, A LIQUEFIED MASS that is moved from the stomach to the small intestine.
