You are studying a transporter found only in the apical plasma membrane of epithelial cells. You treat the epithelial cells with a synthetic peptide that is similar to the extracellular domain of a tight junction protein. The transporter is now found in both the apical and basolateral domains of the plasma membrane. What is the most likely mechanism by which the peptide disturbs the localization of the transporter?

In a freshwater pond, a biologist collects water samples to study microorganisms. Upon microscopic examination, they observe a single-celled organism exhibiting the following characteristics: It has a distinct elongated shape with a tapering tail-like structure. There is a prominent reddish eyespot near the anterior end. Long flagella are visible, extending from the anterior end. Based on these observations, which of the following conclusions can the biologist draw about the organism?    

A feature common to most transmembrane proteins is a(n)?
