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. Note: Consider reviewing how Ruby developed her conclusion on page 8 of this lesson to select the best answer. (1 point) Responses 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. 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. Ruby measures the heights of several species A, B, C, and D plants for a week under different conditions and finds a journal article that describes the growth rate of species A. Ruby measures the heights of several species A, B, C, and D plants for a week under different conditions and finds a journal article that describes the growth rate of species A. Ruby measures the height of a species A plant for a week and finds an anonymous gardening blog that describes the growth rate of species A. Ruby measures the height of a species A plant for a week and finds an anonymous gardening blog that describes the growth rate of species A. Ruby measures the heights of several species A, B, C, and D plants, each species for one week at a time for four consecutive weeks. Ruby measures the heights of several species A, B, C, and D plants, each species for one week at a time for four consecutive weeks. Skip to navigation

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 response indicates that Ruby is measuring all species under the same controlled conditions, which is essential for a fair comparison of growth rates. Additionally, finding journal articles that provide scientific data adds credibility and external validation to her investigation.

Question You weigh 5 kittens all from the same litter and get the following data (in pounds): 1.05, 1.2, 1.15, 1.2, 1.4. Calculate the average weight of the kittens, in pounds. (1 point) Responses 1.15 1.15 1.0 1.0 1.2 1.2 1.3 1.3

To calculate the average weight of the kittens, you 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, 1.4

First, sum the weights: 1.05 + 1.2 + 1.15 + 1.2 + 1.4 = 6.1

Next, divide by the number of kittens (5): Average weight = Total weight / Number of kittens = 6.1 / 5 = 1.22

Therefore, the average weight of the kittens is 1.22 pounds.

However, since this exact answer is not listed in your provided responses, the closest possible answer is 1.2.

Question Which sentence most accurately describes the daily growth rate of plants?(1 point) Responses average plant height divided by total number of plants average plant height divided by total number of plants sum of individual plant heights divided by number of days sum of individual plant heights divided by number of days sum of individual plant heights divided by total number of plants sum of individual plant heights divided by total number of plants average change in plant height divided by number of days average change in plant height divided by number of days

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 focuses on how much the plant height changes over a specific time period, which is exactly what a growth rate is intended to measure.

Question Which example best describes the influence of genetic factors?(1 point) Responses 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. 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. A corn plant is the same height as another corn plant of a different variety. A corn plant is the same height as another corn plant of a different variety. A shrub with good access to sunlight is taller than other shrubs located in shaded areas. A shrub with good access to sunlight is taller than other shrubs located in shaded areas. The adult offspring of a pair of deer is shorter than its parents and obtained fewer nutrients when it was younger. The adult offspring of a pair of deer is shorter than its parents and obtained fewer nutrients when it was younge

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 directly illustrates how genetic factors play a role in determining the size and height of the horse, as it reflects the genetic inheritance from its parents and the breed characteristics.
