Question

A researcher decides to repeat an experiment and reassess results first established in the 1930s about why plants grow towards light. Which of the following is the best reason for conducting this experiment?

a. Weed B produces an organic compound that inhibits root growth for Weed A
b. Equipment and methods developed since the 1930s may produce better data and mechanistic detail.
c. Chloroplast DNA shows clear similarities to cyanobacterial DNA.
d. Sympathetic responses are involuntary physiological responses, often provoked by stress.

Answer 1

The best reason for conducting this experiment is that equipment and methods developed since the 1930s may produce better data and mechanistic detail.

Step-by-step explanation:

The best reason for conducting this experiment is b. Equipment and methods developed since the 1930s may produce better data and mechanistic detail.

Since the original experiment was conducted in the 1930s, there have been advancements in equipment and methods used in scientific research. These advancements could lead to more accurate and detailed data, allowing for a better understanding of why plants grow towards light. By repeating the experiment using updated techniques, the researcher can build on previous findings and potentially uncover new information.
