Its Fins, gills, and tail are all crucial for a sharks survival
Answer:
A critical function of proteins is their activity as enzymes, which are needed to catalyze almost all biological reactions.
The answer is a terminator or transcription terminator. It is part of nucleic acid sequence that marks the end of a gene in DNA during transcription. This progression intercedes transcriptional termination by giving
signals in the newly synthesized mRNA that activate processes which release the mRNA from the transcriptional
complex. These processes comprise the direct interaction of the mRNA
secondary structure with the complex and the meandering activities of
recruited termination

The mass number, also known as an atomic mass number or nucleon number, refers to the total number of neutrons and protons (in a combination known as nucleons) in an atomic nucleus. It determines the atomic mass of atoms. However, while calculating the mass number, the small contribution of mass from electrons is ignored.
Mass number is equal to Number of protons + Number of neutrons
Mass number = 11 + 7 = 18.
Hence, the correct answer is 18.
The ability to analyze DNA via DNA sequencing and other molecular analysis techniques has made it easier to group molecules into categories that represent lines of phylogeny.
Phylogeny is based on similar physical and genetic characteristics between organisms. Before such techniques, scientists were able to discern and group organisms only on the basis of their morphology, or their physical shape or appearance.
