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 respiratory system brings air into the lungs supplying the blood with oxygen. Oxygen is carried throughout the body to the organs and keeps the heart pumping and when the blood circulates back to the lungs the process starts over again.

Blue colors dominate the visible light output of very hot stars (with much additional radiation in the ultraviolet). On the other hand, cool stars emit most of their visible light energy at red wavelengths (with more radiation coming off in the infrared).
initially as temperature increases rate of photosynthesis increases, but after reaching on climax, due to scarcity of water, it starts to decrease
