This question is asking to pick a trend to explain the reactivities of the different metals. Bound water molecules tumble more slowly, producing shortening of T1 and T2. In Arabidopsis, DGAT3 has some specificity for polyunsaturated fatty acids in seed development. We can say the grouped substituent orientations should stay the same. Subsequently, the triacylglycerols are incorporated into lipoprotein complexes termed chylomicrons in the enterocytes by processes discussed in greater detail in our web page dealing with lipoproteins. This is similar to answer choice C. We can eliminate answer choice D. We're left with the correct answer, answer choice A. Nonmetals are found on the right side of the periodic table.
