Answer:
Plasmin
Explanation:
Plasmin is a serine protease also referred to as fibrin digesting enzyme, it is responsible for the dissolving or degradation of blood clot. The process by which plasmin degrades blood clot is called fibrinolysis. Note that plasmin (active) is formed from an inactive enzyme called plasminogen.
Answer:
C). Buffers
Explanation:
The given analogy can best be completed with 'buffers' as it similarly compares with the 'solution pH' like the comparison between 'shock absorbers' and 'vehicle movement.' <u><em>Like the 'shock absorbers' function to help in improvising the vehicle movement and ride quality by lowering the effect reverberations of traveling on a rough platform, similarly, the 'buffers' help in regulating the 'pH of a solution.</em></u>' Thus, <u>option C</u> is the correct answer.
Answer: The brainstem controls autonomic functions through cranial nerves arising from it, along with the medulla oblongata, therefore an injury to the area can cause loss of these functions.
Explanation:
The brainstem comprises of the midbrain, and the pons and medulla of the hindbrain. It is in direct continuation with the spinal cord. Ten cranial nerves arise from this part, and a number of tracts pass through this region. The medulla of the brainstem are particularly involved in maintaining heart rate, breathing and blood pressure. In case of a brainstem injury, the cranial nerves responsible for autonomic functions could get damaged leading to dysfunction and/or the areas of medulla consisting of centres controlling heart rate, blood pressure or other autonomic functions, if damaged could cause difficulties.
