Letter B is single stranded binding proteins
It's one of the electron microscopes, Sorry can't narrow it down for you anymore
Individual
members of the same species are genetically very different because of a process
called meiosis which creates gametes.
<span>During
the meiosis (prophase I) the process called crossing over occurs. Crossing-over
represents the exchange of genetic material between non-sister chromatids of
homologous chromosomes which results in new combinations of genes on each
chromosome (genetic variation).</span>
