Answer:
The respiratory system has cells that produce MOCO OR MUCUS, which trap germs and dust. On their surface they have a large number of cellular structures called CILIAS, whose function is to spread mucus and direct it outwards. In the stomach, the digestive glands produce the STOMACH ACID, which, due to its extreme ACIDITY, attacks and destroys the PATHOGEN MICROORGANISMS that are introduced with food and drink.
Explanation:
In the respiratory and digestive apparatus there are two types of super specialized mucous upholstery, where the cellular world is challenged.
In the respiratory mucosa the production of mucus and the mobilization of the cilia are part of the innate response of the organism as well as the acidity that is generated in the upholstery and in the gastric tract.
They adapt to their surroundings to help stay alive.
Answer:
-nonsense mutation
Explanation:
Non-sense mutations can be described as mutations that to formation of a non-sense or stop codon in mRNA made from mutated gene. There are a total of 64 codons, out of which 61 code for specific amino acids and 3 codons act as stop codon or non-sense codons.
As these codons provide signal for termination of transcription, non-sense mutations lead to formation of a incomplete or truncated proteins due to premature termination of translation.
Thus, the correct answer is 'second option.'
