I don’t know if this is a question but yes a controlled experiment allows you to isolate and test the hypothesis
Answer: alternative A
Explanation: The deeper the layer in water, the <u>less light reaches it</u>. In deeper layers, therefore, it becomes difficult, if not impossible, to photosynthesis to occur. Having in mind that <u>phytoplankton and photosynthetic organisms depend on photosynthesis to survive,</u> they won't appear in such dephts.
These mutations are called neutral mutations. Examples include silent point mutations. They are neutral because they do not change the amino acids in the proteins they encode.
If someone had an inadequate intake of sodium over several days, it would be most difficult for the body to maintain homeostasis.
<h3>Why is sodium important for homeostasis? </h3>
Most of the sodium in our body is present in the extracellular fluid (ECF). The concentration of sodium in the body is measured relative to the amount of water in the body.
Maintaining proper sodium concentration is therefore essential for maintaining water balance in the body. It also helps in the proper functioning of neurons by assisting in the conduction of impulses.
Sodium concentration is also important for muscle contraction. Proper sodium concentration maintains osmolality of the extracellular fluid which maintains the volume of blood and plasma in the body.
Therefore, an inadequate intake of sodium, over several days will affect the homeostasis of the body.
