Answer 1

B.  decreased apoptosis.

Clarify Question
· What is the key concept addressed by the question?
        o This question addresses apoptosis.
· What type of thinking is required?
        o This question is asking you to take what you already know and apply it to this unfamiliar situation.
· What key words does the question contain and what do they mean?
        o Neoplasia is a broad term that includes cancer and other abnormal cell growths.
 
Gather Content
· What do you already know about apoptosis?
        o Apoptosis occurs when a “death program” is activated.
        o All animal cells appear to possess such programs.
 
Consider Possibilities · What other information is related to the question? Which information is most useful?
        o Cells could accumulate due to defective cell death, or apoptosis.
 
Choose Answer
· Given what you now know, what information and/or problem solving approach is most likely to produce the correct answer?
        o If there was decreased apoptosis, that would result in extra cells, or neoplasia.
 
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?
        o This question asked what could cause neoplasia.
        o The question required you to take what you already know and apply it to this unfamiliar situation.
        o Did you recognize that too little apoptosis would result in abnormally large numbers of cells?
