<span>A mirror like copy of the gene is made of RNA</span>
Well to begin with this process is called genetic engineering, the scientists altered the DNA of the chickens instead of altering a protein already in the chickens because when you alter the DNA the offsprings of the chicken will will have the same qualities while if you only alter the protein already in that chicken only that chicken will be able to do the job
Correct answer is ... Seeds have endosperm which provides nourishment for a new plant, but spores do not have any stored food supplies. :)
I believe the answer is comparative anatomy. It is the study of the similarities and differences in the structures of different species. Similar body parts may be homologies or analogies, such that both provide evidence of evolution. Similarities in embryos are evidence of common ancestry. For example all vertebrates embryos have gill slits and tails.
I think about 60 g/m^2 is released into the atmosphere as a result of the metabolic activity of herbivores. Metabolism is the sum of the chemical reactions that take place within a cell of a living organisms and that provide energy energy for vital processes and also for synthesizing new organic material. In herbivores, cellular respiration is the major process that releases carbon dioxide in the atmosphere.
