The abnormal shape of sickled red blood cells causes these blood cells to easily clog or block blood vessels even at the slightest curves. This can prevent other, healthier blood cells from traveling to the places in the body that they need to travel to to help the body function at its best, and as a result, swelling and severe pain can be a problem. An example of such pain that I am thinking of right now is the feeling that you get when you stay upside-down for a long time, causing your blood to rush and stay by your head. Much of that blood stays by your head until you come right-side up again, and I think that that pressure somewhat mimics the feeling of what happens to many with the condition of sickle cell anemia when the blood flow is blocked in certain areas. Hope this helps!

Answer: Ecological succession , or the process in which the structure of a community evolves over time, means that the species composition, density, and distribution of that community is constantly changing as time progresses. A community may eventually reach its climax, the point where the composition remains mostly stable unless some sort of disturbance occurs. Otherwise, communities are constantly changing.
In the example below, a fire destroys the existing species. With a year or two, what are called pioneer species arrive. These may be grasses, low flowering plants, herbs, mosses, and others. Then the populations of these pioneer species, which was once high during the first years since the fire, decreases as other species also
