Dan gave five sunflower seedlings each a different type of fertilizer. he measured the initial and final heights of each plant after a month, then calculated the total growth of each one in centimeters. which is the best method for visually representing the data for comparison? bar graph pie graph data table venn diagram

Option A, Bar graph

Explanation:

A bar graph is the best tool to represent and compare changes between a given set of group during a certain time period of observation.  

A pie chart is more useful while comparing the parts of a whole. Data table is useful when there are several factors of comparison (unlike the case here where only growth in centimeters is being compared). Venn diagram is useful in case of data related to a set and its subsets.  

Thus, among all given options bar graph will be the most appropriate way of representing total growth of all plants in centimeters.

b is dominant over the allele for the white fur.
