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 DNA contains the sugar deoxyribose, while RNA contains the sugar ribose. 2  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.
DNA is a stable, double helix that functions in long-term storage of genetic material, while RNA is a reactive, single helix that transfers information. There are also slight differences in base... DNA is a stable, double helix that functions in long-term storage of genetic material, while RNA is a reactive, single helix that transfers information. There are also slight differences in base pairs between DNA and RNA. The sugar deoxyribose makes up DNA while RNA utilizes ribose. This means that DNA contains carbon to hydrogen bonds, making it very stable. RNA, on the other hand, contains more reactive oxygen to hydrogen bonds.
