I have an upcoming biology test based on living organisms, life processes and cell structures, etc. In our exam board, we're required not to just study 'Mrs. Gren' but, 'Mrs. H. Gren': the 'H' stands for homeostatis. I've tried to check on the overall meaning of it, but I was wondering if anyone could give me the perfect summary of it with just enough detail? What is homeostasis? Thank you!
