If plaque buildup reduces the radius of the artery by a factor of 2, the flow rate becomes 1/16th of the original.
Coronary heart disease results from a deposition of plaque in the blood vessels which transport blood to the heart. When the flow of blood to the heart is hampered or obstructed, the heart can be harmed due to a deficiency of oxygen.
Moreover, if a large section of plaque that is deposited gets displaced from an artery wall, it can get stick in other arteries in the body as well, including those present in the brain.
For convenience, an assumption can be made that the artery is cylindrical in shape with a radius of R. The flow rate of a viscous fluid (blood in this case) is determined by Poiseuille's Law, i.e. Q = (π/8) (ΔP/ηl)r4.

Answer:
Adenosine 5'-triphosphate, or ATP, is the most abundant energy carrier molecule in cells. This molecule is made of a nitrogen base (adenine), a ribose sugar, and three phosphate groups.
Explanation:
Some of the things that can be done when one is not able to sleep are:
1. Make yourself a beverage with warm temperature, so that it could make the body feel more comfortable and cozy.
2. Try to devote the next 15 to 30 minutes in performing something relaxing, like reading a book or yoga.
3. Try to put no light or dim light in a room. The eyes are created to be awake and sensitive in the existence of light. Withdrawing it may assist one in getting to a resting mode, which will eventually help one to sleep.
In childhood for many organisms, there is a "critical period," which is when important learning of certain skills occurs.
The critical period of language learning is a period in the first few years that is crucial for learning a language (language acquisition). After this period, it becomes harder and harder to learn a new language. This is why some immigrants that immigrate later in their lifetime struggle to completely grasp a new language.
