the three kinds of nitrogenous wastes based on the energy required to synthesize them are arranged; Ammonia < urea < uric acid.
Nitrogenous wastes are the nitrogen compounds that organisms use to get rid of excess nitrogen. Ammonia, urea, and uric acid are the most common nitrogenous wastes that animals excrete. Protein metabolism generates all of these nitrogenous wastes.
Ammonia is the most toxic of these nitrogenous wastes, and it is the most common but requires the least energy. Urea is more harmful than uric acid, but it is less harmful than ammonia, reducing the amount of energy required to synthesize it. Uric acid is the least harmful, a non-poisonous particle with four nitrogen molecules. This is useful for birds and reptiles that lay hard eggs because it eliminates the most nitrogen, uses the least amount of water, and is not toxic. It also takes the most energy input.

<h3><u>Answer;</u></h3>
produce a layer of enzyme laden mucus that captures dirt and destroys inhaled bacteria
<h3><u>Explanation;</u></h3>
- Secretions from the highlighted glands <em><u>produce a layer of enzyme laden mucus that captures dirt and destroys inhaled bacteria </u></em>
- <em><u>During inhalation airt that contains dust particles or bacteria or other microorganisms may enter the air ways. </u></em>
- <em><u>The layer of the airway covering the airways, is rich in antimicrobial compounds and mucins that are responsible for removal bacteria and other microorganisms from the airway .</u></em>
- <em><u>This layer consist of mucus that traps, kills, and also inactivates the bacteria. </u></em><em><u>It also contains periciliary fluid which keeps mucus at optimum distance from the underlying epithelia, to enhance bacteria clearance and the motility of cilia.</u></em>
