Imagine that a mutation in the gene encoding the cholera toxin was made. this mutation affects the a-subunit, preventing it from interacting with any host protein. (a) would the toxin be able to enter into the intestinal epithelial cell? (b) would the toxin be able to cause diarrhea?

i think that d. wind is the answer.   i missed the question when i answered a. currents.

the cell is the smallest structural and functional unit of living organisms, which can exist on its own. therefore, it is sometimes called the building block of life. some organisms, such as bacteria or yeast, are unicellular—consisting only of a single cell—while others, for instance, mammalians, are multicellular.
