Explanation:
Anaerobes: They are micro-organisms that do not require energy oxygen for metabolism. They can only survive in an environment that lacks oxygen.
Obligate anaerobes are bacteria typically living in various places naturally. Many of obligate anaerobes living in the human body, in places such as the mouth and gastrointestinal tract (most of the obligate anaerobes present their) where oxygen level present in very low concentration.
Obligate anaerobes do not contain several enzymes needed to detoxifying oxygen present in the cell. Oxygen produces several byproducts in the presence of water such as hydrogen peroxide, it is a week acid and affects no. of enzymes present in anaerobic cells. In a high level of oxygen anaerobic cells become more acidic and not able to function.
So that's why they are found in no oxygen or low oxygen environment like the gastrointestinal tract.
<span>This statement is false. The binomial nomenclature system was used to classify animals, but not until the 1700s when it was first formally introduced by Carl Linnaeus. In ancient times, plants and animals were instead usually just classified in terms of whether or not they were useful, or divided animals into categories such as 'domestic animals, wild animals, creeping animals, flying animals, sea animals'.</span><span />
Male produces signals of bright red, yellow epaulets and long tails.
Males produce bright red and yellow epaulets as well as chevrons on their wings. These bright epaulets attracts the female of this species and helps in the sexual activity of widowbird species.
The males of several widowbird species also grow long tail feathers about half a meter in length. The long tail is favored by sexual selection through female choice of mates. Female prefer long tails red-collared widowbird so we can conclude that male produces signals of bright red, yellow epaulets and long tails.
