Rabbits are very popular domesticated animals, so popular that there are over 300 breeds of domesticated rabbits in the world. You attend a rabbit show and notice that all of the breeds vary in many characteristics, such as size, color, and fur length. You notice that there is weight information on the cages of all rabbit individuals at the show and decide to jot down data for two specific rabbit breeds (in pounds): Breed A: 10, 8, 7, 10, 9, 9, 10, 9 Breed B: 10, 12, 14, 13, 10, 15, 11, 12 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.

2) Factors that could contribute to the different weights seen within breeds include genetics, diet, exercise, and overall health. Some breeds may have naturally larger or smaller body frames, leading to variation in weight. Additionally, rabbits with different diets or levels of physical activity may have different weights.
3) To track and find the growth rate of the two rabbit breeds during an investigation, you would need to measure their weights at regular intervals over a specific period of time. This could be done by weighing the rabbits and recording their weights on a schedule (e.g., every week or month). By comparing the weights over time, you can calculate the growth rate by dividing the change in weight by the time elapsed.

What was the effect of root space on plant growth based on the student's investigation? Use the data from the table to support your answer. Explain how you would know whether this effect was likely due to environmental or genetic factors.

To determine whether this effect was likely due to environmental or genetic factors, a control group would be necessary. The student could have included a third group of plants with the same depth of root space as Group B, but with different genetics. By comparing the growth of the control group to Group B, any differences in growth could be attributed to genetic factors. Additionally, controlling other environmental factors such as water, sunlight, and soil type ensures that the observed effect is primarily due to root space.
