Regarding the recognition of tail-anchored proteins by their targeting machinery: "When the hydrophobic transmembrane α helix at the C-terminus of an ER tail-anchored protein emerges from the ribosome, the tail-anchored-binding domain (TABD) of the Get3 ATPase binds to it. The job of TABD in Get3 is similar to that of the flexible hydrophobic domain in the SRP54 protein of the signal-recognition particle, in that it also has to recognize a degenerate set of hydrophobic α- helices. Therefore, it is not surprising that, just like the corresponding domain in SRP54, the binding site in Get3 is rich in residues."
A. arginine
B. methionine
C. leucine
D. glycine

one would be wind another would be water density

answer:

the water molecules are transferred from the roots to the stem or top parts of the tall tree because of important properties of water which are adhesion, cohesion and capillary action. cohesion is the property of water molecules keeps water molecules in a combined state by sharing of bonds between them at the atomic level. adhesion allows the interaction of water molecules with other substances or substrate. adhesion will cause the attachment of water molecules to the wall of the vessel (xylem) of the plant. capillary action occurs when the adhesive force to the vessel wall is stronger than the cohesive force between water molecules. capillary action mimics the transfer of water from a tube or pipe. in this way water utilizes its property to transfer water from down to top level of the plant.  

d. changes in climate and historical records
