I hope it's an open question, since I can not find the statements.
The monitoring mechanisms are in addition to the regulation of the succession of the four phases of the cycle by the Cdk. They allow the monitoring of fundamental aspects such as the state of the DNA molecules before, during and after their replication (DDCP = DNA Damage Checkpoint), the total completion of the replication before the entry into mitosis (RCP = Replication Checkpoint ) and the correct positioning of all chromosomes on the metaphase plate before sister chromatid separation (MPC = Mitotic Checkpoint).
Disruption of the cell cycle leads either to cell death because the cell can no longer continue its cycle, in the worst case to anarchic proliferation. The major interest of the study of the regulation of the cell cycle and its points of surveillance lies in the fact that these processes are often unregulated in cancers. Knowing the regulation of the cell cycle is therefore fundamental for oncology and can be used to develop new therapeutic approaches.
The comparison of species based on common physical characteristics Thus, the correct option is D.

What is cladistics?</h3>
Cladistics is a method of biological taxonomy that organizes taxa in a branching hierarchy so that all members of a given taxon share the same ancestors and defines taxa uniquely by shared traits not present in ancestral groupings.
Clades, which are collections of organisms made up of an ancestor species and its offspring, are also identified through cladistics.
A cladogram only displays one probable phylogeny for a collection of organisms. It can shed light on the process of evolution. A cladogram should not be viewed as a representation of genuine evolutionary processes, though. It may or may not depict what actually occurred. It merely illustrates what might have occurred.

Answer:
The correct answers are A and B.
Explanation:
Pleiotropy is defined as "when a single gene affects two or more phenotypic characteristic of an organism.". Phenotypic refers to the traits that can be physically observed or measured in an organism, for example height, hair color etc. So the examples of pleiotropy in the given options are in A and B which describe situations where one gene affects two or more phenotypic traits.
I hope this answer helps.
