Nastasia [14]

Answer:

1. Space-filling

2. Ribbon model

3. Wireframe

4. Simple shape

5. Simplified diagram

Explanation:

"attached is the question"

A protein can be visualized using different types of models. The models you use will depend on what you want the viewer to understand.

A space-filling model would show all the atoms that composes a protein. This type of model makes use of spheres, emphasizing the globular structure of the atoms. They are proportional to the actual size of the atom they represent.  Each type of atom is a different color. Even the distances of the spheres are proportional to its size to help viewers better see the actual shape of the protein.

Ribbon model is also a 3D representation of a protein. It shows the only the backbone of the protein. It highlights the folds and coils in a protein, generally the organization. Some versions show the α-helices as ribbons and β-strands are shown as arrows.

Wire frame model is like the ribbon model but it also shows the side chains. It shows the different atoms that are involved. Thin wires show the bonds made between the atoms and the wires bend show the relative location of the atoms.

A simple shape focuses more on the function of the protein overall rather than the internal structures. The shape does not represent a particular protein, merely using a general shape to represent a protein.

A simplified diagram shows more detail than the simple shape. It shows the internal structures as well but like the simple shape model, it focuses more on the function of the protein. A version of it is a solid shape, which does not show the internal structure.

The force of gravity on Planet A is 5.7 m/sec2. How much would an object with a mass of 5 kg weigh on Planet A?
Anestetic [448]
Weight= Mass x Force of gravity
In this case weight= 5 x 5.7 = 28.5

Disruption of the ________ of cardiac muscle tissue would interfere with the heart's ability to beat in synchronous fashion.
Otrada [13]

Disruption in the intercalated discs in the cardiac muscles would interfere with the hearts ability to beat in synchronous manner.

The important salient features of intercalated disc are-

  • These intercalated disc in cardiac muscles of the heart create connections between nearby cells
  • The intercalated disc provides for coordinated operation of the cardiac cells and is highly specialised to facilitate the beating
  • Extensive folds and intercellular junctions for mechanical and electrical interactions between neighbouring cells make up the intercalated disc at the ends of muscle cells

The electrical characteristics of the cardiac muscle cells and the passage of electrical information from one region of the heart to another determine the rate at which the heart contracts and the synchronisation of atrial and ventricular contraction necessary for the efficient pumping of blood.
