The correct answer is d: cDNA.
<span>cDNA or complementary DNA is DNA synthesized usually from messenger RNA (mRNA) by the enzyme reverse transcriptase. Because this molecule is from mRNA it contains only exons. cDNA is also produced naturally by retroviruses, for example, HIV virus.</span>
Scale insects mature as sessile.
Is a disadvantage because sessile means nonmotile, which means food has to be readily there for them which it's just not bc land animals typically have to keep moving to survive
