Introduction:
Bacteria and the archaea are the domain of the prokaryotic organisms. They are microscopic and lack true membrane bound nucleus and other organelles. The bacterial population similar to the other population grow exponentially when the
Answer to Problem 6A
Option (A).
Explanation of Solution
Explanation for correct answer:
Option (A) line I. The line I shows that bacteria is growing exponentially, in the ideal conditions, where the resources are abundant and the conditions are favorable, bacteria grow exponentially. Hence, it is the correct answer.
Explanation for incorrect answer:
Option (B) line II. The line II represents steady growth where the increase the bacterial population is steady, which means some bacteria are growing and dying at a constant rate, but overall growth is there. Hence, it is an incorrect answer.
Option (C) Line III. Line III represents a steady rate of the bacteria, which means the number of bacteria getting added is equal to the number of bacteria dying. Hence, it is an incorrect answer.
Option (D) Line IV. The line IV represents a sudden decline in bacterial population, which means bacteria is exposed to a condition, which is not suitable for survival. This condition can be caused by an effective antibiotic. Hence, it is an incorrect answer.
