Answer 1

Clarify Question
What is the key concept addressed by the question?
        · This question is asking about the differences between microsporidians and blastocladiomycetes.
What type of thinking is required?
        · Evaluate level:
            o This question is asking you to compare and contrast microsporidians and blastocladiomycetes, making it an evaluate-level question.

  Gather Content
What do you already know about microsporidians and blastocladiomycetes? What other information is related to the question?
        · Microsporidians do not possess mitochondria, so they do not carry out aerobic respiration.
        · Blastocladiomycetes do posses mitochondria.

  Choose Answer
  Given what you now know, what information is most likely to produce the correct answer?
        · Since a general characteristic of fungi is a cell wall that is made of chitin, this answer can be disregarded.
        · Rubisco is used in photosynthesis, so this answer can also be disregarded.
        · Phospholipidases and DNA polymerases are produced by many fungi, so neither is a differentiating factor.
        · Since ATP synthase is an enzyme that is used in the mitochondria during aerobic respiration, it would not be present in the microsporidians. ATP synthase could be used to differentiate between microsporidians and other fungi.
 
Reflect on Process
  Did your problem-solving process lead you to the correct answer? If not, where did the process break down or lead you astray? How can you revise your approach to produce a more desirable result?
        · Evaluate level:
            o Answering this question correctly depended on your ability to weigh and judge, or evaluate, microsporidians and blastocladiomycetes. If you got an incorrect answer, did you remember that microsporidians lack mitochondria, or the that aerobic respiration occurs in the mitochondria? Did you have trouble comparing microsporidians and blastocladiomycetes to determine the correct answer?
