A zoo in Southern California has been successfully breeding arctic wolves and they want to exchange some of their extra wolves for kangaroos from a zoo in southwestern Australia. Since it is July, it is quite cold in the other zoo compared to Southern California. What discussion might the zookeepers have about transferring the wolves?

After growing up in Southern California, the individual wolves have lost their ability to adapt to cold temperatures, but their progeny will still get the cold-adapted genes. D. Although the wolves are genetically adapted to cold weather have not grown their cold weather coats. Clarify question: What is the key concept addressed by the question? What type of thinking is required? Gather Content: What do you already know about the cold weather adaptations in wolves? What other information is related to the question?
