Answer:toxic
Explanation:
A ureotelic organism excretes excess nitrogen as urea. Urea is less toxic and needs less water in comparison to Ammonia. Ureotelic organisms include cartilaginous fish, few bony fishes, adult amphibians and mammals including humans. The uricotelic organism excretes uric acid or its salts
3) grass and pine cone
4) lemming, rabbit, insect, squirrel, deer, caribou and moose
5) badger and bear
6) wolf, snowy owl, hawk, fox and ant
7) lemmings would die out because they have no other food source
It depends upon the protein and also where the deletion of the single amino acid has occurred. Does ur alter or disrupt an important fundamental function or aspect of the protein such as the capability of substrates to bind to the active site, or is near a region that is primarily for developing the additional structure of the protein and is not as important. In most cases, a single amino acid change will not cause the protein to lose its complete function of be denatured.
Marshall Nirenberg and Heinrich Mattaeis contributed to out current understanding of the genetic code by discovering genetic codons. Their experiment deciphered the first of the 64 triplet codons in the genetic code by using nucleic acid homopolymer to translate specific amino acids. Their experiment cracked the first codon of the genetic code and showed that RNA controlled the production of certain types of proteins.<span />
