The correct answer is: 'Reptiles are ectotherms and cannot raise their body temperature above that of the environment'. Birds sit on their eggs to incubate the eggs as the body temperature of the adult bird warms up the eggs. Birds are <span>endothermic homeotherms, and maintain a constant body temperature. In contrast </span>reptiles <span>are ectothermic poikilotherms, and their body temperature depends on the temperature of the outside environment.</span>
Answer: c. inheritance of acquired characteristics.
Explanation:
The inheritance of acquired characteristics is a part of Lamarck's theory of evolution. He states that organisms can pass through their genes characteristics that they have acquired in their lifetime to their offspring.
For example, if a giraffe is born with a short neck, and it lenghtens after years of trying to reach the higher leaves of a tree, Lamarck stated that its calves (its babies) would be born with a long neck.
Darwin, publisher of the first Natural Selection theory, said that, by a slight random mutation of the genes, the giraffe with the longer neck would already be born with the long neck. It would be more successful when finding leaves to eat, and therefore produce more offspring with its DNA than the ones with a short neck. As a result, the number of long necked giraffes would grow, and eventually the short necked ones would go extinct.
