Did both sprigs of anacharis produce oxygen? which produced the most? what is demonstrated as necessary by this experiment for photosynthesis to occur? what factor affected the rate in which photosynthesis occurred?

equal distribution i think.

the dna molecules have a negative charge because of the phosphate groups in their sugar-phosphate backbone, so they start moving through the matrix of the gel towards the positive pole. power is turned on and dna fragments migrate through gel (towards the positive electrode).

explanation:

i don't have a definite answer, but i would assume not based on my experiences with my friend when we both were taking a spanish course; however, it would probably still be to your benefit to look at what questions she received, just in case. a language course and a science course differ greatly, after all.
