Ans. Microbial cells.
In humans, various symbiotic microorganism live in digestive tracts and are known as gut flora or gut microbiota, such as various bacteria and fungi.
These microorganisms provide immunity against some pathogenic microbes and help in digestion of some indigestible food compounds.
Examples of these microbial cells include Lactobacillus and E. coli.
Thus, the cells described here are 'cells of microorganisms' or 'microbial cells.'

Answer:
How did Watson and Crick describe the structure of DNA?
Watson and Crick showed that each strand of the DNA molecule was a template for the other. During cell division the two strands separate and on each strand a new "other half" is built, just like the one before. ... By 1962, when Watson, Crick, and Wilkins won the Nobel Prize for physiology/medicine, Franklin had died.
Explanation:
The reactant side of the given chemical equation C2H5OH + 3O2 → 2CO2 + 3H2O contains six hydrogen atoms.
The chemical equation in question is C2H5OH + 3O2 → 2CO2 + 3H2O. This refers to the reaction of ethanol (C2H5OH) with oxygen (O2), producing carbon dioxide (CO2) and water (H2O). From the chemical equation, the reactants side contains one ethanol molecule containing six hydrogen atoms. Hence, in terms of reactants, the number of hydrogen atoms involved in the equation is 6.

The given statement is True.
Coral bleaching is a stressed condition in which is caused by the warmer temperatures.
The algae gets expelled from the corals when there is a high temperature. Earlier the algae used to live in the tissues of the corals which made the corals colorful but as soon as the algae leaves the corals, it turns completely white.
This phenomenon is known as coral bleaching.
