Identify the correct pair of adaptations to environment in desert lizards.

 a. Bask in sun when body temperature is low

 b. Burrowing in soil to escape low temperatures

 c. Insulating body due to thick fatty dermis

 d. Move to the shade when ambient temperature starts increasing

Desert lizards lack the physiological ability that mammals have to deal with the high temperatures of their habitat but manage to keep their body temperature fairly constant by behavioural means. They bask in the sun and absorb heat when their body temperature drops below the comfort zone, but move into shade when the ambient temperature starts increasing.
