AP Biology Exam (units 5-8) Latest Version Graded A+ 10% rule Only 10% of the total energy produced at each trophic level is available to the next level. The amount of energy passed up to the levels of the food pyramid reduces as you go up. 3' vs 5' end of DNA strand replication goes 3'->5' - 3' (of original molecule) is leading strand - 5' is lagging strand adaptive immunity the ability to recognize and remember specific antigens and mount an attack on them altruism ...
