<p>Does anyone know where I can find the answers for Ward's AP Biology Lab #4, Plant Pigments and Photosynthesis... I'm having a difficult time answering the questions and would love some help. Thanks!</p>
<p>which ones? I have done that lab, answered all of the questions, and got it back–80/80 (100 %), not to mention a 99.7 % in the class. What do you want to know?</p>
<p>hey ivysaur!! it would be number 9: shown below is a strip of chromatography paper and a list of five molecules and their various Rf values. Assuming the solvent front traveled 54 mm, place each molecule where it would be found on the finished chromatogram.</p>
<p>If you’re having trouble with the answers, the help you need is not getting answers, the help you need is in understanding the lab so you can produce the answers yourself. Check with your teacher or another student so you learn something.</p>
<p>I read that 25% of multiple choice questions and 1 free response queustion covers the a.p. bio labs. what is the best way to study for these labs?</p>
