Electromagnets can be switched on and off. This is good in a scrap yard because they need to pick heavy pieces of metal and then drop it.

Answer:

The prime advantage of using electromagnets in a device is that it can be easily turned on and off.

Explanation:

The formation of electromagnets is done by winding a wire via a magnetic substance and then passing an electric current through it. The durability of the electromagnet relies upon the size of the electric current via the coil and the number of coils.  

On the other hand, the regular magnets do not need power, however, it is reliant upon the kind of material that is, used to produce it. Thus, it is advantageous to utilize electromagnets in comparison to permanent magnets as the strength of the electromagnet can be amended easily by monitoring the concentration of current flowing through it. Thus, it is easy to turn off and on any device containing an electromagnet.

Which is the correct sequence of the transfer of information in most organisms?
Phoenix [80]
<span>The formation of DNA is a sequential process. First, the DNA molecule is transcribed on to an RNA molecule. This RNA molecule carries the information from the DNA from the nucleus to the cytoplasm, where it encounters ribosomes. The ribosomes then read the information on the RNA molecules and construct a chain of amino acids corresponding to the codons on the RNA molecule. The amino acids combine to form a protein.
Therefore, the correct sequence is <u>C, DNA to RNA to protein.</u></span>
