Answer:
1: Cells
2: Tissues
3: Organs
4: Organ Systems
5: Organisms
Explanation:
1: A Cell is the basic unit of life. Some people refer to it as "building blocks of life."
2: Tissues are groups of cells that work together to achieve a certain task.
3: Organs are groups of tissue that work to make the vital parts of the body
4: Organ Systems are groups of organs that work together to provide for body function. EX: Respiratory System, Circulatory System, Digestive, etc.
5: Organisms are any living thing that have many organ systems that work together. EX: Humans.
Answer:
Option D
Explanation:
From the phylogenetic tree, it can be deduced that the eukarya were derived from the shared common ancestors much later that the bacteria and archae. This separation was based on rRNA data. The tree also shows that the archae appears to be more closely related to eukaryotes than to other peokaryotes.
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.
