The right answer is It led to an understanding of how cancer cells divide so rapidly.

A cancer (or malignant tumor) is a disease characterized by an abnormally large cell proliferation (tumor) in a normal tissue of the body, so that the survival of the latter is threatened.

Control points are programmed between each phase of the cell cycle to verify that the current process is proceeding normally.

This is an opportunity for the cell to identify the occurrence of possible abnormalities in its cell cycle and to trigger either an action of correction of these errors or its self-destruction (apoptosis).

If these errors are not repaired, they accumulate. It is this accumulation, over time, that is at the origin of cancer. It is considered that it takes about ten mutations for the phenomenon of cancerization to appear.

The anomalies that occur are genetic mutations, caused by errors during the replication - or reproduction - of the DNA, and therefore of the genes, when the cell divides.

In the majority of cases, these mutations occur on the DNA of a somatic cell of a particular tissue, for example, on the DNA of a colon cell.

What describes skeletal muscles​
Mashutka [201]

"Skeletal muscle, also called voluntary muscle, in vertebrates, most common of the three types of muscle in the body. Skeletal muscles are attached to bones by tendons, and they produce all the movements of body parts in relation to each other. Unlike smooth muscle and cardiac muscle, skeletal muscle is under voluntary control. Similar to cardiac muscle, however, skeletal muscle is striated; its long, thin, multinucleated fibres are crossed with a regular pattern of fine red and white lines, giving the muscle a distinctive appearance. Skeletal muscle fibres are bound together by connective tissue and communicate with nerves and blood vessels."

Which nursing action is appropriate when conducting a secondary survey during the emergency assessment? which nursing action is
deff fn [24]

The secondary survey or assessment is performed once the primary survey is done and non-life threatening injuries can be evaluated. While performing this kind of assessment it is essential for the clinician to obtain as much information as possible so that one can properly diagnose the injured person.  

In the secondary assessment, the healthcare expert goes via step by step from head to toe to determine what has happened. This can involve and is not restricted to inspection, soft tissue and bony palpation, circulation, special tests, and neurological. Secondary assessment is done to find out the cause of injury, how the injury took place, and how severe is the injury.
