please note that with the sentences with it's there is no other verb
because we already have a verb which is 's
but with its we should have a verb in the sentence because the s here is not a verb
ملاحظة الجملة التي تتضمن its لا يوجد فيها فعل آخر لأن 's هي الفعل أما في جملة its فيجب أن يكون هناك فعل
لأن its ضمير و الضمير لا يغني عن فعل
