B and C
Explanation:
When the Amish came to their new home, they were founding a new colony. This is considered a founding effect.
Now, there is another thing to keep in mind, and that is that the Amish are very strict about their custom, for example, the idea of family and identity. This led them to form couples, only among the members who belonged to the community.
As generations go by, genealogical relationships between individuals in the population become closer. This causes some genes, by mere probability, to become fixed (i.e. they are the only ones left in the population). As a consequence of this, the frequency of rare genes increases (polydactyly). This evolutionary process is known as gene drift.
Well, we can rule out diffusion and osmosis because these are passive processes, so we're left with A and C. I'd say A, because the energy is used in muscle contraction.
They can can cause a difference in temperature which can affect the type of precipitation in the are they can also move storm systems into different areas
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.
