genetic factors and growth quick check
which sentence most accurately describes the daily growth rate of plants? (1 point)
○ average plant height divided by total number of plants
○ sum of individual plant heights divided by total number of plants
○ sum of individual plant heights divided by number of days
○ average change in plant height divided by number of days

Explanation:

To determine the daily growth rate of plants, we need to consider the change in height over time. The growth rate focuses on how much the height changes per day.

• The first option ("average plant height divided by total number of plants") is about average height per plant, not growth rate.
• The second option ("sum of individual plant heights divided by total number of plants") is calculating the average height of plants, not growth rate.
• The third option ("sum of individual plant heights divided by number of days") combines total height with days, which is not a measure of growth (growth is about change in height, not total height).
• The fourth option ("average change in plant height divided by number of days") makes sense: the average change in height (how much height has changed overall, on average) divided by the number of days gives the daily growth rate (change per day).

Answer:

D. average change in plant height divided by number of days
