Ruby has observed that plants 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 concertinaing plant growth rates.
To gather enough evidence to support a scientific explanation concerning plant growth rates, Ruby would need to conduct a well-designed experiment comparing the growth rates of the species in question (Species A, Species B, Species C, and Species D). Here is the statement that describes the process Ruby should follow:
Ruby conducts a controlled experiment where she plants an equal number of individuals from species A, B, C, and D in a garden plot that receives similar sunlight, soil nutrients, and water. Each plant is spaced equally to reduce competition for resources. She measures and records the initial heights of all the plants at the beginning of the growing season. Over a set period, she regularly measures the growth of each plant species at consistent intervals, ensuring to record any significant differences. Ruby maintains consistent environmental conditions and care for all plants to minimize variables. She uses statistical analysis to determine if there are significant differences in growth rates between species A and the other species. If her data show species A grows significantly faster than species B, C, and D, with the results being repeatable and statistically significant, this could be considered enough evidence to support a scientific explanation that species A grows faster than the other garden species.
