B water pollution is the answer
Answer:
The provided events can be classified as:
Initiation
- In prokaryotes, the Shine-Dalgarno sequence pairs with rRNA.
- In E. coli, mRNA binds to the 30S ribosomal subunit.
Elongation
- In E. coli, EF-Tu delivers an aminoacyl-tRNA to the ribosome
- Initiator tRNA enters the P site.
- In E. coli, EF-Tu hydrolyzes.
- Translocation occurs
Termination
- The ribosome has mRNA, an empty A site, and deacylated tRNA in the P site
Translation is the process by which polypeptide chain is synthesized based on the codon sequence of the mRNA (messenger ribonucleic acid).
It is divided into three stages:
Initiation: The small and large sub-units of the ribosome get assembled around the initiation codon. It forms three sites (A, P, and E site) for interaction tRNA and mRNA.
Elongation: Specific charged-tRNA enters from A site and transfers its amino acid to the growing polypeptide chain in P site. Uncharged tRNA exit from the E site. Ribosome moves or translocates to the next codon.
Termination: As soon as ribosome reaches the termination codon, it releases the newly synthesized polypeptide chain.
Answer:
ocean water evaporates and becomes water vapor, then when the droplets grow larger they fall as precipitation

Anticipating that one is about to eat can trigger the cephalic phase of digestion.
The cephalic phase of digestion is the stage during which the stomach responds to the mere sight, smell, taste as well as thought of food. Approximately 20% of total acid secretion takes place before food reaches the stomach.
During this phase of digestion, gastric acid and pepsinogen secretion is activated by the thought, sight or smell of food and also when food is inside the mouth.
The cephalic phase of gastric secretion is moderated completely through the parasympathetic nervous system. A variety of sensory stimuli including the sight, smell, and taste of food induces acid secretion in the stomach.
