I would say physical though.
<span>PCR is a relatively simple process because it only requires three cycles to produce enough of the desired DNA.

Answer:
The inflow of sodium ions.
Explanation:
The generation of the action potential requires the change in the membrane potential of the cell. This membrane potential is maintained due to the unequal distribution of the ions.
The cell potential of the cell is -70mV and maintained due to the presence of potassium ions. The depolarization occurs due to the influx of the sodium ions and results in the change in the membrane potential upto +30mV. The neurotoxin that interferes with depolarization process might affect the sodium ions uptake.
Thus, the answer is inflow of sodium ions.
Answer: Made up of
Explanation:
Composed can mean several things such as being able to remain calm or being made up of something. In this case it is the latter. When they say that something is composed of something else, it means that the first thing is made up of the second thing.
In this case therefore, the oceanic crust being composed of pieces that cover the ocean floor means that the oceanic crust is made up of those pieces.
