Important question for UT Austin

I am applying to the business honors program as my first choice major and deans scholar honors program as my second choice major. However, if I am rejected from deans scholars but accepted into the business honors program, will they not accept me into the regular college of natural sciences and only put me into the business honors program–basically, if I get accepted into my first choice major, will they disregard my second choice major? I really want to double major in business and biochemistry.
