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 concerning plant growth rates.(1 point)
Ruby measures the heights of several species A, B, C, and D plants for a week under the same conditions and finds journal articles that describe the growth rates of each species.

1. ruby measures the heights of several species A, B, C, and D plants for a week under the same conditions and finds journal articles that describe the growth rates of each species.
2. 1.2
3. average plant height
---------------------------
number of days
4. a horse is the same size as its parents and shorter than horses of the same breed that it lives with on a farm
The correct statement is:
Ruby measures the heights of several species A, B, C, and D plants for a week under the same conditions and finds journal articles that describe the growth rates of each species.
The correct answer is:
Ruby measures the heights of several species A, B, C, and D plants for a week under the same conditions and finds journal articles that describe the growth rates of each species.
Explanation:
In order to support a scientific explanation concerning plant growth rates, Ruby needs to gather enough evidence. This includes measuring the heights of several plants of different species (species A, B, C, and D), observing them for a week, and ensuring that they are exposed to the same conditions. By doing so, Ruby can eliminate any external factors that could affect the plant growth rates. Additionally, finding journal articles that describe the growth rates of each species further strengthens the evidence and supports a scientific explanation.
