<u>Answer:</u> In heterogeneous mixture, the composition remains variable throughout.
<u>Explanation:</u>
For the given options:
Homogeneous mixtures are defined as the mixtures that appears uniformly throughout the solution and the particle size or shapes are not different. The composition remains constant throughout.
A solution is defined as the solution in which the components gets completely dissolved in it. Particles are evenly spread in these solutions. These solution does not scatter light falling on it. The composition remains constant throughout.
An amorphous solid is defined as the solid in which the constituent particles of the matter are arranged in the random manner. The composition remains constant throughout.
A heterogeneous mixture is defined as the mixture in which component are unevenly spread throughout the solution. The size and shape of the particles differ in these mixtures. These mixture scatter the light falling on it. The composition do not remains constant throughout.
Compound is defined as the chemical specie which is formed by the combination of two or more different type of atoms. <u>For Example:</u> etc...The composition remains constant throughout.
Hence, in heterogeneous mixture, the composition remains variable throughout.

Answer:
b
Explanation:
The single-stranded regions of DNA are protected during replication by <u>single-stranded binding proteins</u>.
<em>The single-stranded binding proteins are a class of protein found in some living organisms. They bind to single-stranded regions of the DNA during the process of replication, recombination, or DNA repair and protect the DNA from being degraded by nuclease enzymes. In addition to protecting the single-stranded DNAs, they also hinder the single-stranded DNA from premature hardening during replication</em>.
The correct option is b.
