Question

question 3 (bonus) (1 point) overlapping colonies on a streak plate indicate that the loop was properly sterilized between streaks. true false question 4 (1 point) which of the following best describes a “countable plate”? a plate with 1 - 5 colonies a plate with more than 500 colonies a plate with 30 - 300 colonies a plate with exactly 100 colonies

Explanation:

For Question 3, overlapping colonies on a streak plate can indicate improper sterilization of the loop as it may not have eliminated all previous - sample organisms. For Question 4, a countable plate in microbiology is typically one with 30 - 300 colonies. Fewer than 30 may be statistically unreliable and more than 300 are difficult to count accurately.

Answer:

Question 3: True
Question 4: A plate with 30 - 300 colonies
