Which statement correctly describes amphipathic (or amphiphilic) helices and sheets? helices are typically hydrophilic on one surface, whereas sheets usually have both hydrophilic and hydrophobic residues evenly distributed throughout their structure. sheets are typically hydrophilic on one surface, whereas helices usually have both hydrophilic and hydrophobic residues evenly distributed throughout their structure. amphipathic helices and sheets have hydrophilic and hydrophobic residues evenly distributed throughout their structure. amphipathic helices and sheets have predominantly hydrophilic (or hydrophobic) residues on one face.

The correct answer is the last statement.

Explanation:

Amphipathic refers to a substance that comprises both hydrophobic and hydrophilic surfaces. Thus, the given first three statements are incorrect. The amphipathic helices are witnessed on the proteins surfaces in which the hydrophilic region associates with the aqueous phase and the hydrophobic regions associate with the hydrophobic component of the protein.  

Both the amphipathic sheets and helices exhibit primarily the hydrophobic or hydrophilic residues on one face. Thus, the correct answer is the last statement.

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.
