Which of the following statements is true?

Question

The high resistence organisms of the first generation were all killed by the pesticide.
The high resistence organisms only comprise the final population.
The low resistence organisms only comprise the final population.
The third generation (not shown) will be comprised mostly of both low and high resistence organisms.

Answer 1

To determine which statement is true, let's analyze each statement in the context of how pesticide resistance often works in organisms.

1. The high resistance organisms of the first generation were all killed by the pesticide.
   This statement is likely false. If they had high resistance, they are more likely to survive the pesticide application.

2. The high resistance organisms only comprise the final population.
   This statement is likely false as well. While high resistance organisms may be prevalent, it is unlikely that they are the only ones remaining, as some low resistance organisms may also survive.

3. The low resistance organisms only comprise the final population.
   This statement is false; if high resistance organisms survive the pesticide application, then both populations would likely exist in the final population.

4. The third generation (not shown) will be comprised mostly of both low and high resistance organisms.
   This statement is likely true. If both low and high resistance organisms survived the pesticide application, the third generation would likely include both types as they would reproduce.

Given this analysis, the most accurate statement is:
The third generation (not shown) will be comprised mostly of both low and high resistance organisms.
