Answer:

G1/S checkpoint

Explanation:

G1/S checkpoint is one of the points in the cell cycle, between growth phase 1 and DNA synthesis phase, where a cell that has been damaged is sensed by DNA repair enzymes and further degraded by apoptosis. In cancer cells, there is mutation in these DNA repair enzymes and thus nothing to correct the cells from dividing even when damaged and thus there is no arrest of division and cells continue dividing

Answer:

A ( spindle assembly checkpoint)

B ( G1/S Checkpoint)

Explanation:

Transitions between phases of the cell cycle are controlled by checkpoints.

This process is regulated by cyclins, cyclin-dependent kinases and tumor suppressors.

A defect at any of these internal checkpoints would result in mutation that would lead to the formation of abnormal cells.

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.
