The carotid murmur is the presence of an abnormal noise that is heard with the stethoscope placed on the lateral wall of the patient's neck, almost always due to a stenosis of the carotid artery; that is to say, there is a narrowing in the lumen of the vessel, decreasing the amount of blood that goes to the face, head and brain. This narrowness of the vessel is presented by the accumulation of plaques within the arteries (arteriosclerosis).

The diagram below represents levels of organization in living things. Which term would best represent X?
Nutka1998 [239]

The correct answer is C. Tissue

Explanation:

In the diagram, x is between organ and cell level. This implies this level of organization is smaller than an organ but no as small as one cell. In this context, the most suitable term to add to this level is a tissue because these are structures composed of specialized cells, which shows this level encloses cells. Also, a group of tissues forms an organ; this implies the organ is the level that follows the tissue. Examples of this include muscle tissue composed of muscle cells and that is part of organs including the heart.
