intestinal flora

A modest level of ethanol enters the human circulation naturally from intestinal flora, equivalent to a fraction of a drink per day.

<h3>What is intestinal flora?</h3>

inside the intestines are bacteria and other living things.
They aid in food digestion.
Intestinal flora produces vitamins like biotin and vitamin K. Also known as intestinal microflora, microflora, and gut flora.

<h3>Are intestinal flora good?</h3>

Humans have 100 trillion viable bacteria in their intestines.
The intestinal flora is the collective name for these living bacteria, which account for 30% of the faeces bulk.
The intestinal flora contains both useful and dangerous microbes.
They are evenly distributed and the good bacteria take center stage in healthy persons.

<h3>What purpose does the gut flora serve?</h3>

Intestinal microflora primarily serves two purposes:

(1) metabolic processes that result in the absorption of nutrients and energy; and
(2) host defense against invasion by alien microbes.

The immune system's development and balance depend heavily on intestinal microorganisms.

Why the noble gases are found in small amounts in the earth's atmosphere?

777dan777 [17]

Answer:

They have completely filled outermost shell

Explanation:

The noble gases are the rarest and occur in trace amounts in the atmosphere because they have completely filled outermost and this makes them unreactive with other elements.

Elements become abundant as they combine with other species to form compounds.

Noble gases on the other hand have a high level of stability and do not readily combine with other species.

Some of these gases are :

Helium

Neon

Argon

Krypton

Xenon

Radon

They have very high ionization energy and very low electron affinity and so will not readily react.

A Herbig-Haro (HH) object is:_:_________.

Phoenix [80]

Given what we know about Herbig-Haro (HH) objects, we can confirm that they are born from the collision between a jet from a star and clouds of interstellar matter.

<h3>What are Herbig-Haro (HH) objects?</h3>

To put it simply, a Herbig-Haro (HH) object is what we observe as a bright spot in distant space. Upon closer observation we can observe that these giant bright patches are not lone objects, but in fact immense groups of interstellar matter.

<h3>How Herbig-Haro (HH) objects are formed.</h3>

The formation of one of these interstellar groups requires an immense amount of energy. This energy come from the speed at which the materials that form these objects collide.
As stated in the question, the jet released from a star in the process of being born smashes into a giant cloud of dust and interstellar material to form the Herbig-Haro (HH) objects.
This collision happens at hundreds of km/s. To put it into perspective, it would be roughly 500,000 miles per hour.

Therefore, we can confirm that option b, which states, "where a jet from a star in the process of being born collides with (and lights up) a nearby cloud of interstellar matter", is the correct choice for the question pertaining to Herbig-Haro (HH) objects.

The ratio of sizes between the ionic radii of anions and cations in a cell has no influence on the manner of packing for that ce

Morgarella [4.7K]

Answer:

The answer is B. False

Explanation:

The ratio of sizes between the ionic radii of cations and anions in a cell influences the manner of packing for that cell thereby predicting the possible cation/anion coordination number in any compound and establishing the structure of ionic solids.
