Answer:
The correct answer would be thrombin.
The last step in the blood clotting is the formation of a fibrin clot.
Thrombin is the serine protease (protein) enzyme which activates fibrin.
It converts the soluble fibrinogen into the insoluble fibrin which then results in the blood coagulation.
In 1929 the American astronomer Edwin Hubble discovered that the distances to far-away galaxies were proportional to their redshifts. Redshift occurs when a light source moves away from its observer: the light's apparent wavelength is stretched via the Doppler effect towards the red part of the spectrum. Hubble’s observation implied that distant galaxies were moving away from us, as the furthest galaxies had the fastest apparent velocities. If galaxies are moving away from us, reasoned Hubble, then at some time in the past, they must have been clustered close together.

Answer;
The tremors of Parkinson's disease
An undersupply of dopamine is most closely linked to the tremors of Parkinson's disease.
Explanation;
-Parkinson's disease is primarily caused by low and falling dopamine levels. A person with Parkinson's has abnormally low dopamine levels.
-When 80 percent of dopamine is lost, PD symptoms such as tremor, slowness of movement, stiffness, and balance problems occur. Dopamine-generating cells, known as dopaminergic neurons (types of nerve cells) in the substantia nigra part of the brain may have died.
