Clostridium tetani is a bacterial species that causes disease by secreting proteins that disrupt normal neurological function. Without this ability, C. tetani would not be able to cause disease. Preformed antibodies can be used to treat the disease caused by this bacterium. What would you suspect the preformed antibodies are specific to?

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.  

if the type of the food available changes, then the frequency of beak types will change, because birds with beaks more suited to the available food will be more successful over time.
