Question

1. in the word microorganisms, what does the prefix “micro-” mean? a. unusual b. not c. again d. minute

Explanation:

To determine the meaning of the prefix "micro -", we analyze the word "microorganisms". Microorganisms are very small organisms. The prefix "micro -" is commonly known to mean something related to being very small or minute. Option A "Unusual" does not fit as "micro -" is about size, not being unusual. Option B "Not" is incorrect as "micro -" doesn't convey a negation in this context. Option C "Again" is also incorrect as "micro -" has nothing to do with repetition. Option D "Minute" (meaning very small) matches the meaning of "micro -" in "microorganisms".

Answer:

D. Minute
