A species of fox lives in the arctic where the ground is covered in white snow most of the year. These arctic foxes hunt rodents and other small mammals, while their predators include eagles, wolves, and polar bears. A mutation in its DNA causes a fox to have white fur rather than brown. Given this information, would you classify this mutation as a harmful, beneficial, or neutral mutation? Would this make the fox more or less likely to survive? Explain your answer.

The mutation that causes the arctic fox to have white fur instead of brown fur is actually a beneficial mutation because it helps the fox blend in with the snowy environment better. This makes it harder for predators like eagles, wolves, and polar bears to spot them, giving the white foxes a better chance of surviving and passing on their genes to their offspring. So, overall, this mutation makes the fox more likely to survive in the wild.
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.

The average weight of Breed A rabbits is 9 pounds because you add up all the weights and divide by the number of bunnies. The average weight of Breed B rabbits is 12.14 pounds. Some factors that could contribute to the different weights within breeds are genetics, diet, exercise, and overall health. To track and find the growth rate of the two rabbit breeds during an investigation, you could weigh them regularly over a period of time and calculate the change in weight to see how much they are growing.
A student investigated the effect of root space on plant growth. The student grew two groups of plants of the same variety. Both groups received the same amount of water and sunlight and grew in the same type of soil. The plants in Group A were grown in cube-shaped containers that were 3 centimeters deep. The plants in Group B were grown in cube-shaped containers that were 10 centimeters deep. The table shows the student's observations Week Plant Group A (Average Height, cm) Plant Group B (Average Height, cm) 1 2 3 2 3 6 3 5 8 4 7 10 5 8 14 6 10 18 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.

The plants in Group B with more root space grew taller than the plants in Group A with less root space. In Week 6, Group B plants were 18 cm tall while Group A plants were only 10 cm tall. This shows that having more root space can help plants grow bigger and taller. To know if this effect was likely due to environmental or genetic factors, you could try growing the plants in different soil types or changing the amount of sunlight and see if the same pattern happens.
