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>
A point mutation is a mutation that affects only a single nucleotide of a nucleic acid. They involve substitution of one base for another which changes the complementary base as well in DNA, they may also involve insertions and deletions of a single base pair. I therefore think the point mutations in a DNA sequence may profoundly have an effect on the synthesis of proteins, or may also have no effect on protein synthesis at all. These mutations can be beneficial to an organism, however they are more commonly neutral or harmful.

There are many theories about why living thins sleep, however, scientists are still unsure about what the answer to this question may be. Some say it is because of its restorative powers - after a good night's sleep, you feel rested, and all your brain and bodily functions work better than when you are exhausted. During sleep, some rejuvenating and growth hormones are created, which again adds to our advantage. You also relieve stress that has accumulated during the day. These are some of the reasons why we have to sleep.
Mitosis is the process by which a newly formed zygote after fertilization begins to divide into multiple cells.

- Mitosis is a type of cell division that results in two daughter cells each having the same number and kind of chromosomes as the parent nucleus, typical of ordinary tissue growth.
- The major purpose of mitosis is for growth and to replace worn out cells.
