Let's look at each of these in turn: 1  Whey protein concentrate-WPC contains low levels of fat and low levels of carbohydrates (lactose). 2  The percentage of protein in WPC depends on how concentrated it is. 3  Lower end concentrates tend to have 30% protein and higher end up to 90%.
The Lake Bottom. Conditions at the bottom of large ponds and lakes do not change much throughout the year but dramatic changes in abundance of particular amoebae have been noted (O'Dell, 1979).
Shape, movement and nutrition. Amoebae move and feed by using pseudopods, which are bulges of cytoplasm formed by the coordinated action of actin microfilaments pushing out the plasma membrane that surrounds the cell.
