If a patient's zygomatic arch has been traumatically depressed or the patient has flat cheekbones, the arch may be demonstrated by modifying the smv projection and rotating the patient's heada 15 degrees toward the side being examinedb 15 degrees away from the side being examinedc 30 degrees toward the side being examinedd 30 degrees away from the side being examined

Option (A).

Explanation:

The zygomatic arch is also known as cheek bones. The cheek bones are formed by the temporal's bone zygomatic process. The zygomatic arch also explains the evolutionary relationship of the organism.

The flat cheek bones of the patient can be demonstrated by submentrovertex (SMV) projection. The arch can be demonstrated by the patient's head rotation to the 15 degree towards the side being examined.

Thus, the correct answer is option (A).

this is true, assuming that the allele is completely recessive and incomplete dominance is not a factor.

the three components of a nucleotide are the nitrogenous base, the phosphate group and the five-carbon sugar.
