Answer:
<em>Scientific models</em><em> are used to predict and elaborate the behaviour of the real objects in the field of physics, chemistry, ecology and earth science. </em>
<em>It is used to gain improved </em><em>understanding of the processes and systems. </em>
Explanation:
However, every model have some limitations because they are not the representative of every possible scenario. For instance, relationship between time and distance is the idea model, study of cell and its various parts uses physical model, predicting earthquake uses computer model.

Answer:
A) Elastin
Explanation:
Elastin is the principle load-bearing protien present in the wall of aorta. It is the protien which coil and recoils like a spring within the elastic fibres and accounts for elasticity of blood vessels. As during excerise , afterload is increased ,thus a stretch is produced in the vessels. Similarly im warm environment the vessels dilate this this stretch is produced by elastin.
The correct answer is a molecule.
It is relevant to consider the compositions of the body in terms of basic levels of the organization, which enhance in complexity: subatomic particles, atoms, molecules, organelles, cells, tissues, organs, organ systems, organisms, and biosphere.
The voltage-gated sodium channels come under the molecule level of structural organization. It plays an essential role in action potentials.
