<h2>
Nucleus - control center</h2>
The nucleus is called the control center of the cell because:
- The genetic material which is the essence of life is hosted in the nucleus – the DNA-which presents the code of life or information or instructions regarding:
- The structure and function of each cell and the organ it is present,
- Numerous activities of life like reproduction, metabolism, growth, development, etc.
- The nucleus replicates the genetic information and passes to the new daughter cells, generation after generation to continue the life processes.
- The nucleus DNA transcribes the code or information for protein synthesis to the RNA to synthesize proteins in the body which carry out many essential functions in the form of structural proteins, antibodies, hormones, pigments, etc.
- The nucleus DNA synthesizes enzymes which carry out functions like metabolism.
Answer:
well a hypothesis is literally a scientific assumption or theory used to describe what they think is going to happen during a experiment
Answer: His phenotype will be Bb. He will have brown hair because it is a dominant trait.
Explanation: Heterozygous indicates that there are two different genes present in a genotype (Bb instead of BB or bb).
<h2>Answer</h2>
What are organic compounds
- An Organic compound is any member of a large class of gaseous, liquid, or Solid chemical compounds whose molecules contain carbon.

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.
