All of these are necessary
Answer is the first option Place a metal paper clip on a table and slowly bring each electromagnet closer to the paper clip to see which can attract the paper clip from a greater distance.
I don't know why but I find your questions a bit too easy..

Hope I helped, sorry if not tho
The best answer is D
A freely suspended magnet will always point in the North - South direction in the absence of any other magnet. This suggests that the earth itself behaves as a magnet which causes a freely suspended magnet (or magnetic needle ) to point always in a particular direction namely North and South.
The south pole of the earth's magnet is in the geographic north because it attracts the north pole of the suspended magnet and vice versa. However it is important to note that the position of earth's magnetic poles are not well defined because they are spread over an area.
Answer:
1. When DNA is duplicated from mRNA which DNA, mRNA uses a <u>U</u> nucleotide instead of T.
2. If the mRNA sequence is GUACUGUAC, the DNA Sequence is <u>CATGACATG</u>.
Explanation:
1. The only thing that changes from a DNA sequence to an RNA sequence is that the thymine (T) in DNA is changed to Uracil (U) in RNA.
2. There should be no Uracil (U) in a DNA sequence–– only ATCG. Just matching with the given pairings.
G can transcribed to C.
C can be transcribed to G.
A can be transcribed to T.
U can be transcribed to A.
