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.
This is copied to the mRNA first. The differences between DNA and RNA are that 1) RNA has uracil in place of thymine and 2) RNA uses ribose instead of the 2-deoxyribose in DNA. There are both double stranded and single stranded DNA and RNA in nature so this is not a defining difference.he difference between DNA and a chromosome has to deal with an intermediary-genes. DNA is deoxyribonucleic acid, which is a nucleic acid. It is made up of four bases-adenin â¦ e, cytosine, guanine and thymine. When these four bases are arranged in a segment, it is called a gene.
