Answer:
so??????????????????????????????
You use "it's" as a formal Contraction, it's short for 'it is' or 'it has'.
For example, 'it's a wonderful day's
You use "so" when you are describing something
For example, 'it's so hot'
"So" is also another word for "very", which is where the word originally generated. it's often mixed up with "such", but dont worry! you'll learn English alot soon!
The research had used 24 petri dishes which were identical from the beginning.
Unfortunately during application of the hand sanitizer to 18 of this dishes (6 for each type of sanitizer) but did not include opening of the other 6 petri dishes which should have provided this 24 dishes similar conditions as they were all exposed to the environment. On list the experiment would be more conclusive if the following conditions were applied
Sanitizer A - 6 petri opened and applied with sanitizer
Sanitizer B - 6 petri opened and applied with sanitizer
Sanitizer C - 6 petri opened and applied with sanitizer
No Sanitizer - 6 petri opened with no applied sanitizer
