Answer:
B
Explanation:
CRISPR-Cas9 is a gene-editing mechanism that is harnessed from bacteria’s immune system used to cut apart foreign genetic material such as that of bacteriophages. CRISPR-Ca9 has a guide sequence that is used to identify the target sequence. The Cas9 enzyme cuts this target DNA and is replaced with the required piece.
In cancer treatment, the mutated DNA can be replaced, this way, with the wild type.

Explanation:
Prokaryotes (which are divided into two groups- bacteria and archaea).
According to disruptive selection, individuals not favored
are those that reproduce less and have middle-sized gametes, while organisms that are favored and have great
traits reproduce more. Disruptive selection is also known as diversifying
selection because this type of selection can divide populations of species. The
organisms with weaker traits eventually separate with the organisms with
stronger traits, and they may be diverse enough to form a separate species.
