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.

Answer: Prokaryotic cells differ from eukaryotic cells in that they lack any membrane-bound organelles, including a nucleus. Instead, prokaryotic cells simply have an outer plasma membrane, DNA nucleoid structure, and ribosomes.

Answer:
B. There will be two cells each with 36 chromosomes.
Explanation:
The products of mitosis are called diploid cells, and they each have the complete set of chromosomes. These cells are usually important for activities such as growth, repair etc. They make up our normal body (somatic) cells. Therefore, the answer is 36, only 36 matches the description of genetically identical cells
Answer:
A. Water molecules are split.
Explanation:
The light dependent reactions of photosynthesis require the energy in sunlight to proceed. Structures called photosystems which contain chlorophyll absorb the light from the sun to generate excited electrons, which are transferred to electron carriers ATP and NADH.
These electron carriers are used in the light-independent reactions of photosynthesis.
During this process, the high energy electrons are passed to an acceptor molecule and replaced with an electron from water. This splitting of water produces H+ ions and oxygen as a byproduct. The splitting of water is called photolysis
Answer:
The answer is D.
Explanation:
In geometry, parallel lines are lines in a plane which do not meet; that is, two lines in a plane that do not intersect or touch each other at any point are said to be parallel. By extension, a line and a plane, or two planes, in three-dimensional Euclidean space that do not share a point are said to be parallel.
