Answer:
Speed of blood past the constriction becomes two times the speed of blood flow in the rest of the artery.
Explanation:
For an ideal fluid flow condition, the equation of continuity is applicable which means that the flow of any fluid at a given point of time at two different cross section remains same at constant density
Thus,
Substituting the given values in above equation, we get -
Thus, speed of blood past the constriction becomes two times the speed of blood flow in the rest of the artery.
The answer is <span>B. fibrin.
Through the process of elimination: thrombin and thromboplastin are enzymes so these choices are incorrect. Platelets are actually cells, which leaves us B. fibrin as the correct choice.
</span>A fibrinogen is a protein involved in the formation of blood clot. It is converted by enzyme thrombin into fibrin during blood clot formation.
I believe the answer is loosely packed sand sized particles. Brainliest is appreciated
