Answer:
1) both pieces becomes a magnet.
2) both has north and south pole.
Explanation:
When the magnet is broken into two pieces, both pieces of magnets act as a real magnet which makes magnetic field around them. These newly made magnets have their own north and south pole. When the north pole of both magnets come close together so they repel each other. The reason is that when they are present in joint form, they have a single north and south pole but when they are broken into pieces both have separate north and south pole.
Humans are more closely related to hogs than hogs are to guinea pigs.
Explanation:
The difference in the amino acid sequence of a protein is used to know the relation between organism i.e. how closely they are related.
It is known that proteins are the result of DNA sequence ie genes of the organism.
The gene or protein is compared between organisms to understand the evolutionary evidence and similarities between them.
The less is the difference the more is the two organisms closely related as in the case of hog and human which have only 1 amino acid difference in their insulin enzyme. While guinea pig is having a difference of 17 amino acids so it is expected to be distantly related.
These relations helps the scientist to resolve the issues of crisis say insulin. They zero out the possibility of extracting the enzyme genes of possible organism and increase the yield.
