Food web only contains interactions between trophic levels while an interaction web shows both trophic and non-trophic interactions.
The cellular process shown in the image as x, y and z are mentioned below:
X is Replication. It is the process by which double- DNA Replication is the process by which double stranded DNA makes its own copies. Each strand on its separation, synthesizes a complementary stand.
Y is Transcription. It is the process by which copying of the information from a strand of DNA into a new molecule of mRNA, with the help of an enzyme RNA polymerase.
Z is Translation. It is the process in which genetic code on mRNA is decoded to produce the specific sequence of amino acids to form a polypeptide chain.
Translation of mRNA into a peptide occurs in sequences of 3 nucleotides called codons. Each codon codes for one amino acid. Therefore, as the ribosome reads the codon sequence, it recruits a t-RNA carrying the respective amino acid. A peptide bond is thereafter formed on the growing amino acid chain before the ribosome translocates to read the next codon. This continues until the ribosome reads a stop codon signaling the end of the peptide.
There are five major types of infectious agents: bacteria, viruses, fungi, protozoa, and helminths. In addition, a new class of infectious agents, the prions, has recently been recognized
higher. cancerous cells have a higher mitotic index than regular cells because the cells are constantly dying. hope this helps :)
