If the volcanic ash from an eruption extends to 3.6 miles into the atmosphere, how many kilometers does this represent? (hint: 1 mile = 1.6 kilometers.)
a. 2.3
b. 3.2
c. 5.8
d. 8.5

i might be wrong but i think its a. let me know if i’m right and have a good rest of your day!

the answer is lactic acid from anaerobic respiration. the acid in lactic acid is what creates sore and burning muscles. if you think about how acid burns that will give you a clue for questions like this.
