There are over 400 breeds of dogs in the world and all are maintained as pure-bred stocks through selective breeding,which aims to maintain a closed genetic lineage. Most dog traits follow simple genetic rules.
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.
