What is the standard for determining the sufficiency of evidence in a sexual assault case?

"[I]n reviewing a challenge to the sufficiency of the evidence, the relevant inquiry is whether, on review of the entire record in the light most favorable to the judgment, any rational trier of fact could have found the elements of the offense beyond a reasonable doubt." (People v. Young (2005) 34 Cal.4th 1149, 1180.) "The same standard also applies in cases in which the prosecution relies primarily on circumstantial evidence." (Id. at p. 1175.) "In deciding the sufficiency of the evidence, a reviewing court resolves neither credibility issues nor evidentiary conflicts. [Citation.] Resolution of conflicts and inconsistencies in the testimony is the exclusive province of the trier of fact. [Citation.] Moreover, unless the testimony is physically impossible or inherently improbable, testimony of a single witness is sufficient to support a conviction." (Id. at p. 1181.)
