Answer:
More than two complete sets of the chromosomes (polyploidy).
Explanation:
Assembly of spindle microtubules assist the chromosomes to arrange in the equator of the cell during metaphase. This is followed by the splitting of centromere and segregation of sister chromatids towards the opposite poles of the cell to ensure equal distribution of chromosomes among the daughter cells.
Any drug that prevents the assembly of the spindle apparatus would not allow the alignment of the chromosomes in the cell's equator. This would prevent the anaphasic segregation of daughter chromosomes to the opposite poles.
Some of the resulting daughter cells are most likely to have more than two sets of chromosomes.

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.
