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.
(4 points)
Short Answer Rubric (4 points)
Based on the given information, the mutation in the fox's DNA that results in white fur instead of brown fur can be classified as a beneficial mutation. This is because the white fur would provide better camouflage in the arctic environment where the ground is covered in white snow most of the year.
The white fur would make the fox more likely to survive because it would be harder for its predators (eagles, wolves, and polar bears) to spot it against the snowy background. This improved camouflage would increase the fox's chances of successfully hunting its prey and avoiding being hunted by predators.
Therefore, the beneficial mutation of white fur increases the fox's adaptability and survival in its arctic habitat.

The mutation in the fox's DNA that results in white fur instead of brown fur can be classified as a beneficial mutation. The white fur provides better camouflage in the snowy arctic environment, making the fox more likely to survive by being harder to spot by predators.
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.
(4 points)
1) The average weight of Breed A is (10 + 8 + 7 + 10 + 9 + 9 + 10 + 9) / 8 = 8.75 pounds. The average weight of Breed B is (10 + 12 + 14 + 13 + 10 + 15 + 11 + 12) / 8 = 12.5 pounds.
2) Factors that could contribute to the different weights seen within breeds include genetics, diet, exercise, and overall health. Genetic variations can influence the growth and size of rabbits, while differences in diet and exercise levels can also affect weight.
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, such as monthly or weekly, and record the data. By comparing the measurements over time, you can calculate the average growth rate by determining the change in weight divided by the time elapsed. This would provide insights into how the rabbits are growing and developing.

A student investigated the effect of root space on plant growth. The student grow bwo groups of plants of the same variety. Both groups received the same amount of water and sunlight and grew in the same type of soll. The plants in Group A were grown in cube-shaped containers that were 3 contimeters deep. The plants in Group Bwere grown in cube-shaped containers that were 10 centimeters deep. The table shows the student's observations

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 holy due to environmental or genetic factors.
(points)
Based on the data from the table, it can be observed that the plants in Group B, which had 10 centimeters deep containers, showed significantly higher average heights compared to the plants in Group A, which had 3 centimeters deep containers. This suggests that root space had a significant effect on plant growth.
To determine whether this effect was solely due to environmental or genetic factors, further investigation is needed. One way to differentiate between these factors is by conducting another experiment where plants from Group A and Group B are swapped to grow in different containers. If the plants originally from Group A show improved growth when placed in the deeper containers (Group B's containers), it would indicate that the effect is primarily due to environmental factors like root space. On the other hand, if the plants originally from Group B still exhibit superior growth even when transferred to the shallower containers (Group A's containers), it would suggest that genetic factors are more influential in determining plant growth.

Based on the data, it can be observed that plants in Group B, which had deeper containers (10 cm), had significantly higher average heights compared to plants in Group A, which had shallower containers (3 cm). This suggests that root space had a significant effect on plant growth.
To determine whether the effect was due to environmental or genetic factors, further investigation would be needed by conducting experiments to manipulate the root space and observing the resulting growth patterns.
