Explanation:
there are larger irregular shaped cells with separate cell walls
Answer:
Lock and key, where correct fit between components is critical.
Explanation:
Reproductive isolation may be defined as the evolutionary and physiological differences that prevent the mating of the different species. This process is critical for the speciation.
Pre reproductive mechanism prevents the meeting as well as mating of the different group of organisms. The genital structure of the insects match and unique within the species. The genital structure of the male and female species fit with each other as the key fits into its lock.
Thus, the correct answer is option (e).

For polypeptide chains, its a vital part involved in the breaking down of Proteins.
Proteins->Proteoses->Peotones-><u>Polypeptide</u>-> amino acids.
