the E refers to Ecology, which emphasizes populations, behavior and things of that nature. The M which refers to Molecular contains questions about cell structure, organic/inorganic compounds and human anatomy. Although there is are 60 questions that must be answered for both tests, you will able to pick E or M after the 60 questions and answer 20 more which focuses on the subject you picked. In my opinion the Biology E would be a better test to take if you did not study as much as you liked to as it involved more reasoning rather than factual information. If you're confident in your knowledge of biology, you should take Molecular as they're straight forward know it or don't know it types of questions.

No. "Malpigian tubules are structures found in insects, like grasshoppers, that aid in excretion. They excrete nitrogenous wastes wastes into the digestive tract and from there, out of the body." -According to the Barron's SAT Biology E/M subject test book. There was a practice question that asked "Which of the following are matched incorrectly?" The correct answer was Malpighian tubules-earthworms.
On MacConkey agar, a key difference between E. coli and Pseudomonas spp. is their ability to ferment lactose. E. coli ferments lactose, producing pink/red colonies due to acid production. Pseudomonas spp. do not ferment lactose and therefore appear as non-lactose fermenting colonies that are colorless on MacConkey agar.
the differences between the paramecuim cell and the elodea cell is that paramecuim- hunt for food, live by itself, single cell creature. elodea- make their onw food, cannot live alone, multicullar cells. (lots of cells)
Dichotomous keys are tools common in biology used to classify organisms where there are only two options -- the organism either possesses a particular trait or feature or it does not (Moulton, 2004, p. 109). The answer to this question is then used to help biologists and tell them which questions to ask next until all traits have been have been included and investigated (Moulton, 2004, p. 109).Moulton, Glen E.
