The cardiac notch is the concave area in the left lung that leaves a space for the heart to accomodate. The corrcet answer is <u>cardiac notch</u>.
<h3>
What is the cardiac notch?</h3>
The left lung has superior and inferior lobules, one oblique fissure, it is adjacent to the heart, the aortic arch, the thoracic aorta, and the esophagus. It also has a cardiac notch.
The cardiac notch is a concave lung area where the heart accommodates. Its main function is to leave a space for the heart to lay. It is placed in the anteroinferior border of the superior lobule of the lung.
Since the cardiac notch is the area where the heart is placed, it only appears in the left lung.
The correct answer is cardiac notch. The medial surface of the left lung has a cavity that accommodates the contents of the mediastinum. It is called the _<u> cardiac notch</u>_.

Explanation:
Answer:
<u>Temperature</u> is most likely the reason of protein unfolding (denaturation).
Explanation:
In the figure attached, coiled (3-dimensional) protein structure is changed to 2 dimensional structure in which protein is unfolded. This is most likely the result of heating proteins which destroys the hydrogen bonds and non-polar hydrophobic interactions that are necessary to establish the tertiary structure of proteins. Principally, increased temperature results in the increased kinetic energy of atoms within a molecule. If the amount of heat is sufficient to break the hydrogen bonds, protein molecule can unfold to 2D structure as shown in the figure.
