In three to five sentences, 1) calculate the average weights of the two rabbit breed groups, 2) describe some factors that could contribute to the different weights seen within breeds, and 3) describe how you would track and find the growth rate of the two rabbit breeds during an investigation.

1) The average weight of Group A, which consists of Flemish Giants and English Lops, is 12 pounds, while the average weight of Group B, which consists of Holland Lops and Netherland Dwarfs, is 4 pounds.

2) Factors that could contribute to the different weights seen within breeds include genetics, diet, exercise, and overall health. Flemish Giants and English Lops are larger breeds that naturally weigh more, while Holland Lops and Netherland Dwarfs are smaller breeds that have a smaller frame and weigh less.
3) To track and find the growth rate of the two rabbit breeds during an investigation, you could record the weights of each individual rabbit at regular intervals, such as weekly or monthly. By plotting the weights on a graph over time, you can calculate the average growth rate of each breed and compare them to see any differences in growth patterns.
