Both sentences use *parce que*. You have to compare “parce qu'elle” in the first sentence to “parce que ce” in the second. The last *e* of *parce que* is [elided][2] only in the first because *elle* starts with a vowel but not *ce*.

Therefore, the only difference lies in the choice of the subject pronoun in the second clause of this sentence.
Whether to use *il/elle* or *ce* has [already been discussed][1] on French Language. It is not linked to the use of *parce que* and it's particularly suttle in these examples. In the two example you gave both *elle* and *ce* would do, but it is not always the case.
