Question 1

Question

A)
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.

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

Answer 1

The best response 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, each species for one week at a time for four consecutive weeks.

This statement indicates that Ruby is collecting data from multiple plants over a longer duration, allowing for a more reliable and robust comparison of growth rates across the different species. This systematic approach is essential for drawing a scientific conclusion.

Question 2
A)
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.

Answer 3

Question 2

To calculate the average weight of the kittens, add the weights together and divide by the number of kittens.

Weights: 1.05, 1.2, 1.15, 1.2, 1.4

Sum of weights = 1.05 + 1.2 + 1.15 + 1.2 + 1.4 = 5.1 pounds

Average weight = Total weight / Number of kittens = 5.1 / 5 = 1.02 pounds

Since 1.02 is not among the options, it appears that the response choices may not reflect the correct average weight calculated. The closest reasonable option given the problem might typically be more precise in terms of the average.

Question 3

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 essence of calculating growth rate over a specific time period, which is key to understanding how plants grow.

Question 4

It seems that the question is incomplete regarding the examples provided. However, a common example of genetic factors influencing plant characteristics could be:

A shrub with good access to sunlight that grows tall due to its genetic predisposition.

If you have more details or options for Question 4, please provide them for an accurate response.

A corn plant is the same height as another corn plant of a different variety.

Answer 5

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 highlights the genetic inheritance that influences the traits of the offspring, showing that the horse's size is related to its parents and the breed, which reflects genetic factors.
