Homologous structures are structures found in one species that have the same basic anatomical structure and embryonic origin as those found in another species. If homologous structures are found on organisms of two different species, the species are related, even if only distantly. Which of the following structures are homologous and illustrate evidence of an evolutionary relationship?
A.
a bird's wing and a butterfly's wing
B.
a wasp's wing and a dolphin's flipper
C.
a catfish's fin and a bee's antenna
D.
a whale's flipper and a cat's leg

as the gila monster consumes the eggs or young of the desert cottontail and gambel's quail, thus its main food supply is only accessible for a restricted time duration every year. however, for this, the gila monsters exhibit three adaptations, which elevate their survival rate in the desert condition.  

first, is that they possess huge bodies, and can consume greater concentrations of food during a small period. secondly, they require to feed infrequently as they can accumulate fat in their tails. ultimately, their rate of metabolism is very low, so that they can burn their reservoirs of fat gradually.
