Dear Sir or Madam,
I'm a 10th grader at Hilton High School doing a biology lab on duckweed.
What I really need to know is what kind of effects oil has on duckweed. I
need this information to complete this and to get a good grade. Please
respond as soon as possible. I need to write the lab up soon. Thank you.
Sincerely,
Jill Welcher
