The best statement that describes Ruby gathering enough evidence to support a scientific explanation concerning plant growth rates 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.**
This option indicates that Ruby is collecting data from multiple species under controlled conditions, which allows for a more reliable comparison. Additionally, referencing journal articles strengthens her investigation by providing scientific backing to her findings.

To calculate the average weight of the kittens, you need to add all the weights together and then divide by the number of kittens.
The weights of the kittens are: 1.05, 1.2, 1.15, 1.2, and 1.4.
1. **Add the weights**:
\( 1.05 + 1.2 + 1.15 + 1.2 + 1.4 = 6.1 \) pounds
2. **Divide by the number of kittens (5)**:
\( \frac{6.1}{5} = 1.22 \)
The average weight of the kittens is 1.22 pounds.
Since the options provided do not include 1.22, rounding it to one decimal place gives us **1.2**.
So, the correct choice is:
**1.2**

The sentence that most accurately describes the daily growth rate of plants is:
**average change in plant height divided by number of days**
This definition captures the concept of the daily growth rate by taking the average change in height over a specified period (days), thus providing a clear measure of how much the plants grow each day.

The example that best describes the influence of genetic factors is:
**A horse is the same size as its parents and similar height to other horses of the same breed that it lives with on a farm.**
This statement indicates that the horse's size is influenced by its genetics, particularly by being similar in size to its parents and other horses of the same breed. The other examples incorporate environmental factors (like nutrients and sunlight) that may affect growth but do not specifically highlight genetic influence as effectively as this one.
