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.
Rating Newest Oldest. Best Answer: RNA differs from DNA in a number of ways. 1) RNA is single stranded molecule, while DNA is double stranded. 2) RNA is a polymer with ribose and phosphate backbone, while DNA has a deoxyribose(1 less oxygen) and phosphate backbone.lso, adding to the previous answer. RNA is also single stranded, while DNA is double stranded, making it a double helix. RNA is involved in the production of proteins, as it is the rubric for protein synthesis. There are many different types who play different roles in the cell.
