Agene mutation causes the ldl receptor to have a different shape so that it no longer interacts with ldl and receptor-mediated endocytosis is not stimulated to take ldl into cells. ldl then increases in the extracellular fluid, which includes plasma in the bloodstream, causing high blood levels of ldl. ldl is a transport particle for cholesterol, and is known as "bad cholesterol." this is an example of which theme in physiology?

The table presents the average day and night temperatures in five cities. it also reveals whether a city receives substantial rainfall (wet climate) or little rainfall (dry climate). which city’s rocks are likeliest to experience frost wedging, and why? a) city a because the consistently subzero temperature would prevent water from melting b) city b because it is a wet region and the temperature fluctuates around the freezing point c) city c because it receives plenty of rain fall and the weather is moderately cool d) city d because the hot and dry weather would cause rocks to absorb water
