How does the structure of phylogeny charts explain homologous structures in organisms? a. new species branch off ancestral species, so two species can have similarities in body structure. b. all old species die off as soon as new species emerge, which explains why current species have traits of extinct species. c. in different lineages of organisms, two organisms may have similar structures that evolved in different ways. d. all organisms mutate their genome automatically when an environment changes, creating new traits and structures.

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.
