Answer:
Aldehydes have antibacterial, antifungal, antiviral and sporicidal activity. These are helpful to destroy the spores of Bacillus subtilis and Clostridium sporogenes. Glutaraldehyde and formaldehyde are commonly used aldehydes in disinfectants.
Quaternary ammonium compounds work by denaturing the proteins of the bacterial or fungal cell, affecting the metabolic reactions of the cell and causing vital substances to leak out of the cell, causing death.
<span>The first great discovery of genetics happened In 1865, when Gregor Mendel published a paper on his study of inherited traits in plants. He is often called the founder of genetics.

Genetic variation allows for a greater chance of a population surviving. For example, if a plant species acquires a disease, without genetic variation the disease would just keep getting passed on to the next identical organism and the population would decline and eventually die. But genetic variation prevents that from happening, because you have so many other species in the ecosystem, and genetic variation is a product of sexual reproduction meaning that the offspring of the diseased plant has a possibility of not inheriting the disease.
Answer:
Archaebacteria
Explanation:
Carl Woese categorised the bacteria into two domains called the Archaebacteria and the Eubacteria.
The Archaebacteria is the group of bacteria which can survive in the extreme condition as they posses the characteristics of both the prokaryotes and some eukaryotes. The bacteria are known as the extremophiles.
In the given question, the bacteria which lives in the gut of the human uses methane gas and thus are known as the methanobacteria. These bacteria are considered the archaebacteria as they methane for survival.
Thus, Archaebacteria is correct.
