Answer:
Search the the periodic table for more info
Explanation:
Metals are, well, metals. Examples are Iron, Copper, and Aluminum.
Non Metals are simple; they are not metals
Metalloids are complex to define, so I will let the Oxford Dictionary explain for me;
an element whose properties are intermediate between those of metals and solid nonmetals or semiconductors.
(the oxford dictionary)
For obtaining an adequate amount of DNA samples for DNA fingerprinting, polymerase chain reaction (PCR) can be used.
Polymerase chain reaction (PCR) is a technique that is used to amplify the DNA sample. The steps included in PCR are:-
1. Denaturation of the double-stranded DNA (at around 95°C)
2. Annealing of the primers to each of the single-stranded DNA templates ( at around 65°C)
3. Extension or elongation of the primers by considering every single-stranded DNA as a template. This elongation is carried out by <em>Taq </em>polymerase (at around 72°C).
With each cycle of PCR, the DNA sample is increased by 2ⁿ. Here, 'n' represents the number of PCR cycles.

A. True
However, this is not necessarily the only factor that makes this true.
