They have large appetites, so unless you planted enough for yourself and the butterflies, it can be a depressing sight to see your food crop munched down to its stems by an army of hungry caterpillars. Planting a separate crop of fennel (or any related member) can help preserve the butterflies in your garden.I especially like Florence fennel, or finocchio, a bulbing variety that gives you a vegetable, an herb, and two spices over its lifespan.n the back of my garden, I have a small patch of fennel (Foeniculum vulgare) that grows year-round and stands five feet tall.
1 The only difference between ribose and deoxyribose is that ribose has one more-OH group than deoxyribose, which has-H attached to the second (2') carbon in the ring. 2  DNA is a double stranded molecule while RNA is a single stranded molecule. 3  DNA is stable under alkaline conditions while RNA is not stable.
Differences. 1  DNA contains deoxyribose as the pentose sugar, while RNA contains ribose. 2  Both nucleic acids contain the bases A, C, and G, but DNA has T where RNA has U. RNA doesn't contain T while DNA doesn't contain U. 3  DNA is typically double-stranded while RNA is typically single-stranded.
