NEED HELP ASAP LIKE RN PLEASE ILL GIVE POINTS AND EVERYTHINGI DONT HAVE A LOT OF TIME LEFT D. Reviewing Scientific Methods Used in Biology
You investigate the question
"What effect does additional nitrogen have on plant
growth?" You set up an experiment in which you planted bean seeds in two groups.
After the seeds germinated, Group A was given an application of fertilizer with addition
nitrogen. Group B was grown under identical conditions, except the fertilizer it received
contained no additional nitrogen. You measured the height and mass of the plants for
one month. The results are illustrated here.
