Cyclins
are the chemicals that regulate the cell cycle. Cyclins work by regulating the timing
of the cell cycle in eukaryotic cell. Cyclins activates cyclin dependent
kinases (CDKs) (an enzyme that works by adding <span>negatively charged phosphate groups to other
molecules in a process called phosphorylation) by binding to it to form a cyclin-Cdk
complex. This complex then functions by acting as a signal to the cell to move
to the next cell cycle phase. At the end of the event, the cyclin is degraded, Cdk
is deactivated, therefore signaling exit from a specific phase.</span>
The dependant variable would be the salmon, because they depend on the water and pollution levels to give a result.
Answer: The correct answer to the fill in the blank is Mitosis.
Mitosis is a type of cell division that results in the formation of two daughter cells having the same number of chromosomes as compared to their parent cell. Thus, by producing more number of identical cells, mitosis helps in the growth and repair of tissues.
Thus, after removal of cyst from the liver of Bob, the cells would grow and repair the area through mitosis.
