E-coli bacteria which most useful in the routine monitoring of microbial pollution are gram negative rods and this is common indicator organism of water contamination.
It is important to identify enteric bacteria which is one of the major causes of diarrhea disease is bacteria and that detection of pathogenic bacteria is a global key to the prevention and identification of food borne diseases and enteric infections like diarrhea.
The extent of water contamination can be measured using these indicator organisms. This fecal coli-form group has been used as the most common indicator of general wastewater contamination because they are abundant and easy to identify.

A specific organ on which a hormone, drug, or other substance acts
Answer:
Acids and bases that are completely ionized when dissolved in water are called strong acids and strong bases There are only a few strong acids and bases, and everyone should know their names and properties. These acids are often used in industry and everyday life
Explanation:
A weak acid will react with a strong base to form a basic (pH > 7)
Answer:
1.) Inflated pod shapes (Cc) in the F1 generation
2) See attached image for the work out of the cross from P generation to F2 generation.
3). CC- 1/4, Cc- 1/2, cc- 1/4
Explanation:
This question is related to the pod shape trait encoded by a single gene in pea plants. The alleles for inflated pod shape (C) is dominant over the allele for constricted pod shape (c). This means that allele "C" will be expressed over allele "c" in a heterozygous state.
The two truebreeding parent plants will have genotypes: CC (inflated pod shape) and cc (constricted pod shape). When these two plants are crossed, an all heterozygous plant with genotype: Cc will be formed in the F1 generation. Since, C is dominant over c, the F1 Cc plants will have an inflated pod shape phenotype.
The F1 Cc plants are self-crossed to produce the F2 generation offsprings i.e. Cc × Cc. The gametes C and c will be produced by each F1 parent, which will be used to draw a punnet square (see attached image). From the cross, offsprings with genotypes: CC, Cc and cc are produced in the F2 generation.
CC (phenotypically inflated pod shape)- 1/4
Cc (phenotypically inflated pod shape)- 1/2 or 2/4
cc (phenotypically constricted pod shape)- 1/4
