20. Essay ok can i just say i am so thankful to all the people who put their answers here? like OMG. i owe you all my life 😭 thanks no name they were all correct except i had two alternative questions
8. Here are the steps of cellular respiration, except
C) electrolysis
15. What activity uses ATP to lower body temperature?
C) panting
these are 100% correct Answers are on the question but other than that no names are correct Agree on both. thank you very much my love
