Text
sometimes i swear the answer key that must’ve been submitted to blackboard is wrong
#what do you mean#'after a half-life passes which of the following has happened? a. the parent isotope decreases b. the same amount of time has passed since#the last half-life c. the daughter isotope increases d. both a and b e. both b and c f. both a and c#g. all the the above h. none of the above'#how is the answer NOT all of the above????#ALL OF THOSE HAPPEN WITHIN ONE HALF-LIFE#THE AMOUNT OF TIME FOR ONE HALF-LIFE TO PASS IS ALWAYS THE SAME#UNLESS EVERY SCIENCE TEACHER IVE HAD SINCE GRADE 9 HAS BEEN LYING TO ME!!!!!#and the daughter isotope ALWAYS increases CORRELATIONALLY with the parent isotope DECREASING#i did a second attempt and put both a and c since i thought that's what ??? what??? what?????#utterly confused. was there no right answer.#tales from diana#there were some other ones too on my retake attempt that just didn't make sense w my original answer OR my changed answer#every multiple choice question i got wrong on my first attempt i STILL got marked as wrong on my second attempt#so i was like????#my professor goes through and grades them all manually after the exam date#especially bc of the diagrams that half to be labelled where if you don't label them exactly how blackboard EXPECTS you to#they don't get marked as correct. like i used a comma for a multiple-answer instead of the word 'and'#and when i changed it to 'and' on my second attempt i got full points#but the multiple choice ones i got wrong. there were only five of them. but like. fuck it. at least two of them i was RIGHT on fuck it.
