Your health care provider may do a blood test called a complete blood count to find out if your bone marrow is making the right number of platelets: A normal platelet count is 150,000 to 450,000 platelets per microliter of blood.Risk for bleeding develops if a platelet count falls below 10,000 to 20,000.our health care provider may do a blood test called a complete blood count to find out if your bone marrow is making the right number of platelets: A normal platelet count is 150,000 to 450,000 platelets per microliter of blood.

Apr 19, 2015. A cutbank is a feature of a meandering stream. When a stream channel meanders, the stream channel becomes assymetric. The highest velocity flow within the channel is located near the outer portion of the meander loop. Thus this is where erosion occurs, This steep erosional bank is called the cut bank. Conversely, deposition occurs on the inside of the meander loop and is called a point bar.
Meandering rivers erode sediment from the outer curve of each meander bend and deposit it on an inner curve further down stream. This causes individual meanders to grow larger and larger over time. Meandering river channels are asymmetrical. The deepest part of the channel is on the outside of each bend. The water flows faster in these deeper sections and erodes material from the river bank. The water flows more slowly in the shallow areas near the inside of each bend. The slower water can't carry as much sediment and deposits its load on a series of point bars.
