Answer:
The populations become adapted to different environments and eventually become so different that they cannot interbreed to produce fertile offspring.
Speciation is the evolution of one species into two different kinds, and when they become isolated, that is the final step, since they cannot interbreed any longer.
<h2>
Answer</h2>
The right option is (A).
<h2>
Explanation</h2>
The RNA gets its information from DNA to synthesise the proteins. It is different from DNA also due to the difference in one nitrogen basis as uracil. The thymine, the nitrogen basis that is only present in DNA is replaced with uracil to form RNA coding. The uracil also contains the same features as thymine has in DNA strains. Uracil makes a double H-bond with the adenine but does not contain CH4 group which is present in thymine.
Answer:
No, The respiratory system does not work alone in transporting oxygen through the body. The respiratory system works directly with the circulatory system to provide oxygen to the body. Oxygen taken in from the respiratory system moves into blood vessels that then circulate oxygen-rich blood to tissues and cells.

Answer:
Post translation farnesylation may be defined as a type of prenylation in which the isoprenyl group is added to the cysteine residues of the protein. This modification is important for protein and membrane interaction.
Basically two types of amino acid are required for the farsenylation modification. The signal peptide sequence is the short amino acid sequence that targets the ribosome in the endoplasmic reticulum. The sequence is generally lysine, aspartic acid, glutamic acid and leucine. The second sequence must be Caax (C is cysteine, a is aliphatic amino acid and X consists of C terminal amino acid.
