The statement Bonds in the hydrogen peroxide are weakened in catalase's active site, allowing the chemical reaction to occur is the answer. Catalase is an enzyme in the liver that breaks down harmful hydrogen peroxide into oxygen and water.
Answer: DNA is a polymer of nucleotides, which consist of a sugar, a phosphate group, and a nitrogenous base
Explanation:
Every molecule in the human body are formed by the chains of particular substances. These components are arranged orderly as linked chains to give the structure called DNA.
The components include nucleotides—this is also considered the chemical substance in the human body which helps in the formation.
In this formation of chains, nitrogenous bases will also be linked to form a polymer of DNA.
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.

Answer:
e. derived characters
Explanation:
Any characteristic change which is transfer to the new species from ancestors but is different from the original character. It will be called as derived character.
But if the same character is transfer from ancestor to the new species this will called as ancestral character.
