can i do a biology/similar course at uni without the science a-levels?

hi. i'm a college student who is doing a level 3 diploma in creative media production (the course is 2 years and equivalent to 3 a levels). i also do a baccalaureate course alongside that which i think (but i'm uncertain) is equivalent to an a level too. i didn't realise i would have such a big interest in biology for uni/career while i was making my post-GCSE decisions.

i passed all of my GCSEs with all A*s/As, with the exception of Bs in maths/numeracy. i got AB for science double award.

i don't exactly know what course i would like to do yet at uni but i am interested in microscopy, how the muscles and organs work during exercise/resting periods, healthy lifestyles & diet.

initially, i thought to do journalism so that i could be a journalist/magazine editor. i'm no longer interested in studying journalism at uni because i feel i will have learned enough by the end of college since i also did media studies at GCSE and my college course has significantly developed my skills. i've got other relevant GCSEs for a career in journalism. also, it isn't necessary to have a degree in journalism to become a journalist.

i'd like to develop my understanding in biology and specialise in a career linking to that. perhaps i could even combine media and biology by going into a health direction for a magazine/journalism.

my intention right now is to complete my 2 year media course for UCAS points and to not let my hard work go to waste, and i will look into online biology courses to do at the same time.

i would be grateful for opinions and advice on this. what can my next steps after college be? would my best bet be to do a foundation year first? and what type of courses seem suitable with my interests?
