Which best exemplifies the concept of neuroplasticity?
KonstantinChe [14]
The correct answer is "the formation of new brain cell connections as the result of reading a book".

Usually, neuroplasticity is apparent in young children when the central nervous system has an abundance of neurons. This is always in the context of forming new brain cell connections or synapses that will lead the person to access the information quicker. This also exemplifies the principle of use and disuse when it comes to knowledge. 

The other choices concerns the skeletal system, cardiovascular system, and the endocrine/reproductive system; all of which do not have a relation with neuroplasticity.

All of the following contributes to turbulent blood flow except A) when there are irregularities in the vessel wall. B) at high
GaryK [48]

All of the following contributes to turbulent blood flow except  third and fourth heart sounds.

<h3><u>Explanation:</u></h3>

The blood flow in human body is always described to be laminar. Some conditions cause the high flow when there is an ascending aorta. This causes the laminar flow of blood into turbulent. When this occurs the flow of the blood will not be smooth and linear.  

When the kinetic energy in the fluid flow increases the turbulent flow of blood occurs. Both the magnitude and the direction of the flow changes in this type of blood flow. These are caused by the irregularities in the vessel walls, flow rates to ne higher and opening of the valves of the heart.
