Answer:
Process of the cells, tissues, organs, and organ systems all working together to maintain a stable internal environment are best defined by the term homeostasis (option B).
Explanation:
All living organisms perform their functions properly by maintaining some conditions of the internal environment constant, such as temperature, pH and amount of water or electrolytes. This also guarantees a healthy state and a longer life.
The maintenance of the organic balance is done by an internal regulation system, called homeostasis. Homeostasis means <u>all the processes aimed at preserving the balance and fulfilling the organic functions properly</u>.
The other options are not correct because:
<em> A. </em><u><em>Digestion</em></u><em> is the process by which nutrients are converted into small molecules that are easily absorbed by the body.
</em>
<em> C. </em><u><em>Excretion </em></u><em>is the process of eliminating waste from metabolic and organic processes.
</em>
<em> D. </em><u><em>Disequilibrium</em></u><em> is the term applied to the failure or loss of ideal conditions or balance.</em>
