It will take 1,000,000 times slower for Hydrogen Peroxide to decompose
Hydrogen peroxide is a toxic compound that usually destroys cell membrane. Also, it is a byproduct of metabolism that must be broken down quickly because it can cause damage to the cells. Moreover, catalase is an enzyme that is found in almost all the living organism and function by catalysing the decomposition of hydrogen peroxide into water and oxygen. However, the decomposition of hydrogen peroxide is very slow and cannot sustain human life in the absence of catalase.
The answer is A.
The tight pairing of the homologous chromosomes is called synapsis. In synapsis, the genes on the chromatids of the homologous chromosomes are precisely aligned with each other.
