Answer:

Polymerase chain reaction (PCR)

Explanation:

Polymerase chain reaction (PCR) is a method by which a target DNA fragment is amplified to produce millions of copies. In PCR, the Taq polymerase enzyme uses nucleotides and primers to replicate a small DNA segment <em>in vitro</em> and produces two DNA molecules. The newly formed DNA molecules are denatured by heating to facilitate their replication to produce four double-stranded DNA molecules. In this way, the number of DNA molecules is doubled in each cycle. Therefore, the small amount of DNA obtained from the minuscule spot of blood on a murder suspect’s shirt can be amplified using PCR.

It would be most difficult for the body to maintain homeostasis if over several days someone had an inadequate intake of:_______
Liula [17]

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.
