What is q1?Show answer
Distinguish between structural, physiological and behavioural adaptations using one example for each. [3 marks]
What is q2?Show answer
A desert kangaroo rat survives without drinking water by producing very concentrated urine, sheltering in burrows during the day, and metabolising fat to release water. Classify each adaptation and explain how the three combine to achieve water balance. [3 marks]
What is q3?Show answer
Refer to the mallee fowl. (a) Classify the mound-building behaviour. (b) Explain how the mound regulates egg temperature.
