Write a null and alternative hypothesis for a What is life? lab that we did using the biuret's test. Is what I wrote the correct way to write a null and alternative hypothesis?
Null: There is no difference presence of peptide bonds in the sterile Martian soil, sterile sand or the control group of water.
Alternative: There is presence of peptide bonds in the sterile Martian soil, but not the sterile sand or the control group of water.
