What are 3 adaptations of a yak?

Yaks have several adaptations that help them survive in their harsh, high-altitude environments. Firstly, they possess a thick, long coat of fur that insulates them against extreme cold and harsh winds. Secondly, yaks have large, muscular lungs and a unique hemoglobin structure, allowing them to efficiently utilize oxygen in low-oxygen conditions at high elevations. Lastly, their broad, flat hooves provide stability and traction on rocky terrain, enabling them to navigate the mountainous landscape effectively.
