<span>The statement is true. Protozoan contaminations are parasitic maladies brought on by living beings in the past characterized in the Kingdom Protozoa. They incorporate life forms characterized in Amoebozoa, Chromalveolata and Excavata. I hope it helps.</span>
They must be capable of restraining and treating animals<span> of substantial size and their is a larger demand so more jobs are available and the daily work conditions may vary. they do treat live stock so they might be in different locations.</span>
Answer:
Gas exchange is crucial to sustain life because it rids the body of carbon dioxide and provides oxygen to the body.
Explanation:
Gas exchange in living beings is a mechanism that involves the incorporation of oxygen (O₂) into the organism and the elimination of carbon dioxide (CO₂). This exchange takes place in the pulmonary alveolus and in cells and tissues.
- <em><u>During respiration, the inspired air - loaded with O₂ - is exchanged with the CO₂ contained in the blood, taking advantage of the former and eliminating the latter during expiration</u></em><em>.
</em>
- <em>When the oxygenated blood is taken to the tissues, O₂ is passed to the cells, which are deprived of the CO₂ produced by metabolism.
</em>
The reason why gas exchange is crucial for the sustain of life is because it is the mechanism that allows the entry of O₂ necessary for cellular functions, as well as providing a means of CO₂ elimination.
