6 (3 points) A Siamese cat has an operation in the abdominal region. During this operation a patch of fur is shaved off. When the fur regrows, it is much darker than the fur in the surrounding area. How can this be explained? Choose the correct answer from below. Question 6 options: When the fur is shaved, the skin in that area is no longer insulated and becomes cooler in temperature. This increases the activity of the temperature sensitive enzyme, which prevents the destruction of pigment in that area. Hence, there is more pigment within the skin at that area, and when the new fur grows back it is much darker than the fur in the surrounding area. The skin becomes much cooler in temperature when the fur is shaved. The temperature sensitive enzyme is inactivated in cooler temperatures, preventing the enzyme tyrosinase catalysis from occurring. The new fur is exposed to increased amounts of melanin and grows back much darker than the fur in the surrounding area. Under normal conditions where fur is present, the temperature dependent enzyme is able to work unabated, and acts to prevent melanin from being produced. However, when the skin is shaved the cooler temperature prevents the enzyme from working correctly, and more melanin is produced. This leads to the new fur growing back darker as it is exposed to greater amounts of pigments near the hair follicle. The skin becomes cooler in temperature at the region where the fur is shaved, thus the temperature sensit
