Question

SCIENCE: GENETIC FACTORS AND GROWTH.

RUBY HAS OBSERVED THAT DPLANTS IN HER GARDEN VARY IN HEIGHT. SHE WANTS TO INVESTIGATE WHETHER A PLANT SPECIES (SPECIES A) GROWS FASTER THAN THE OTHER GARDEN SPECIES (SPECIES B, C, AND D). SELECT THE STATEMENT THAT DESCRIBES RUBY GATHERING ENOUGH EVIDENCE TO SUPPORT A SCIENTIFIC EXPLANATION CONCERNING PLANT GROWTH RATES.
NOTE: CONSIDER REVIEWING HOW RUBY DEVELOPED HER CONCLUSION ON PAGE 8 OF THIS LESSON TO SELECT THE BEST ANSWER.

Answer 1

Ruby could collect data on the height of each plant species over a period of time, measuring their growth rates regularly to compare the differences between species A, B, C, and D. By having a large sample size and tracking the growth of each plant consistently, Ruby can gather enough evidence to support a scientific explanation concerning plant growth rates.
