Diameter of E. coli is_ to_ micrometer:
Correct answer: C. 1.1-1.5
- A. 0.5-1.5
- B. 2.0-4.0
- C. 1.1-1.5
- D. 2.0-6.0
Explanation
The correct diameter range for E. coli is 1.1-1.5 micrometers, as E. coli cells are typically around this size. Option C is correct because it accurately captures this range based on the usual size of these bacterial cells. Option A, although close, slightly underestimates the upper end of the range. Options B and D overestimate the size, suggesting dimensions that are not typical for E. coli, which are generally smaller and more consistent with Option C.
