Changes in the trilobite exoskeleton can be attributed to changing environments and competition for survival
The relation ship between primary and tertiary structure of a protein is they both have a sequence of amino acids in a polypeptide chain or of amino acids in a primary structure determines its three-dimensional shape.secondary and tertiary structure . hopes this helps
Answer:
Un depredador y sus presas coevolucionan, el depredador se vuelve más eficiente en perseguir y matar a sus presas y las presas dearrollan nuevas defensas y formas de escape. La coevolución impone presiones selectivas. Éstas a su vez llevan a una carrera armamental de adaptaciones mutuas progresivas
Explanation:
Answer: The table shows 3 domain<em> Bacteria , Archae and Eukarya</em> on the basis of the difference in sequence of nucleotide in the rRNA and cells lipid structure and its sensitivity towards antibiotics.
Explanation:
The three domain system was given by Woese and others. They classified the organism into three domain based on the sequence of the nucleotides in the ribosomal RNA and lipid structure (cell membrane) and its sensitivity towards antibiotics.
rRNA was useful for classification because they carry out the same function and its structure has a very little change over the period of time. So, by studying the dissimilarities and similarities in the rRNA we can compare how closely related the species are.
The lipid cell structure(some might contain peptidoglycan others might not) of these three domains are different and their sensitivity towards antibiotics are also different so, these characters combinely helps in classification system.
