Hey guys! I have been stuck on this question for a while and tried looking in my text books and even searching it up on the internet, but there isn't much I have been able to use! Would anyone mind trying it?
a.) Describe why Hydrogen, Iron, Phosphate and Sodium are important ions in organisms. (7 marks)
My teacher said I should write about a paragraph but I don't see how I can! Any help would be much appreciated!
Thanks!
