7 The phоtоgrаph shоws а yаk. See addendum Question 7 Yaks are cattle that live at high altitudes, such as in the Himalayas.They are well-adapted for the low temperatures and low levels of oxygen in the air. These adaptations include: • a thick layer of fat below the skin• large lungs and a large heart• many small red blood cells• presence of fetal haemoglobin throughout their adult life. (a) Triglycerides are fats.Describe the structure of a triglyceride. (2)
