Unit 5 Lesson 9 Everything is correct, 100% 🙂 Nunya and Taylor are right, I received a 100% thank you. taylor you were right about the last one everything is fine! and i am in connexus and taylor is right Just help is 100% correct just help helped me 😀 Nunya is 100% correct and the last answer for me was also different, the last answer for connexus is exothermic. 100% Nunya is 100% right! just help is ok! tysm!! 100% Nunya is 100% right 🙂 (Cell Respiration Quick Check)
1) sugar
2) heat
3) It is less electronegative than oxygen
4) lactic acid
5) exothermic noise Thank you Thank you Taylor!!! yes @just help merciuuuuu always just today! 04/04/22
