They are known as seven-transmembrane receptors because of the number of times (7 times) they travel through the cell membrane while interacting with G proteins.

Each GPCR is extremely specialized to a given signal, and humans alone have about 1,000 distinct GPCRs. GPCRs are made up of a single polypeptide that has been folded into a globular shape and encased in a cell's plasma membrane. The biggest family of receptors and membrane proteins in the human genome are G protein-coupled receptors (GPCRs), which have about 800 members, of which half are olfactory. Numerous endogenous signaling molecules can activate GPCRs, which are involved in various physiological processes.

As a result, we can state that the seven-transmembrane receptors are so named because they couple with G proteins and pass through the cell membrane seven times.

All right.
Differences with the Historical Model:
1. That model shows the planet's orbits as perfect circles, not ellipses. 
<span>2. Aristotle believed in a geocentric (Earth centered) solar system, while it actually is heliocentric Sun centered). </span>
<span>3. That model didn't show all the planets we know today, such as Neptune, Uranus, etc. </span>
<span>4. A lot of that model was based on religious beliefs. 
</span>Differences with Modern Model:
1. Our model shows the orbits as ellipses. 
<span>2. Our model shows a heliocentric solar system. </span>
<span>3. Our model shows all the planets we know today. </span>
<span>4. Our model has nothing to do with religion. 
</span>Similarities Between Both Models:
1. They both are based on the same solar system. 
<span>2. They both show the inner planets, the Moon, the Sun, Jupiter, and Saturn. </span>
<span>3. The both were made by many observations of the sky.

What can you conclude about the amount of dna that is associated with each nucleosome?
cestrela7 [59]
The amount of DNA that is associated with each nucleosome is a approximately 200 bp. This is determined by treating chromatin wwith a certain enzyme that cuts DNA. This enzyme is called DNases. Every chromosome has hundred of thousands of nucleosomes that are joined by DNA strands that pass between them.

The picture is a scientific model which is used to explain the concept of the water cycle by means of pictures and descriptions.

<h3>What is a scientific model?</h3>

A scientific model is a representation which may be in form of pictures, illustrations, objects, or ideas which are used to explain a particular concept by scientists.

Scientific models are usually employed to explain either difficult to understand concepts or scarcely observable phenomena in order to enrich the knowledge and comprehension of others.

The given illustration is an example of a scientific model. It is used to explain the concept of the water cycle. By means of pictures and descriptions, the various processes of the water cycle can be fully comprehended.

Also, by means of a cyclical illustration, the model helps to explain that the water cycle is a continuous repetitive process.

In conclusion, scientific models may be in form of pictures, illustrations or objects.
