5 0

In modern cosmology, the origin of the Universe is the instant when all the matter and energy that currently exist in the Universe emerged as a result of a great expansion.

<h3>Theories about the origin of the universe</h3>

  • may change due to further investigations

<h3>in astronomer proposed a new theory about the evolution of the universe what is the next step the astronomer should take to make his theory reliable</h3>

  • publish the theory in a scientific journal to let people know about it

<h3>where negatively charged particles would most likely be found in an atom</h3>

  • outside the core

With this information, we can conclude that Electrons – Negatively charged particles located in the electrosphere; Neutrons – Neutral charged particles that, like protons, make up the nucleus of the atom. The attraction or repulsion of bodies depends on the nature of the electric charge: Bodies with charges of the same nature (or sign) – repel each other.

spin [16.1K]
This has something to do with winter seasons. You see, during winter days, <span>the sun is further down in the sky, so the same circle of sunlight covers a wider area, so there is less light per plant. In this case, those plants that are pointing straight at the sun have higher chances of growing better. Hope this answers your question.</span>

SSSSS [86.1K]

The correct answer is 97761 * 2, L6050, Z44.8, Z89.11.  

In the CPT index when one looks for Prosthetics/Training, then one is directed towards 97761. The code is repeated for every 15 minutes. As 30 minutes are spent in training, so 2 units are reported. In the HCPCS level II codebook when one looks for Disarticulation/Wrist prosthesis, one is directed towards codes L6050, L6055. On the basis of description, the prosthesis is reported with code L6050.  

In the alphabetic index of ICD-10-CM, when one looks for fitting/device NOS/prosthetic (external), then one is directed towards the code Z44.8. In the index when one looks for the absence of organ or part (complete or partial)/wrist and hand (acquired) then one is referred towards the code Z89.11.

What function do the alveolar sacs serve in the respiratory system?
Brrunno [24]

These alveoli are the smallest types of lung tissue, and one of the most important. In addition to being the primary means by which oxygen enters and carbon dioxide escapes the bloodstream, these small pouches of air are also the reason why the lungs do not totally collapse when a person breathes out. This is because they contain a cell that secretes a special chemical to lower the surface temperature to prevent lung collapse. The alveoli also contain other cells that secrete chemicals to attack and remove any foreign objects in the lungs, such as dust, dirt and other debris.

In addition to making up alveolar sacs, alveoli also form alveolar ducts. It is estimated that there are more than 300 million alveoli in the human lungs, all of which are located in either alveolar ducts or sacs that are found at the end of the smaller passageways, or bronchioles, in the lungs.


SHORT ANSWER:

Alveolar sacs contain tiny pouches called alveoli, whose primary function is gas diffusion. These clusters of alveoli have thin walls that allow oxygen to pass easily from the lungs into the bloodstream and carbon dioxide to flow from the blood to the lungs so it can exit the body.
