Answer:
43%
Explanation:
When you collect blood in a tube and centrifuge it, the elements that compose it separate in three distinct layers:
- Plasma: water, proteins, nutrients.
- Buffy coat: white blood cells, platelets.
- Hematocrit: red blood cells.
If 56% of the blood sample is plasma and 1% is white blood cells and platelets, then the hematocrit is 100% - 56% - 1% = 43%.
Deposition of eroded material I believe is correct because Sedimentary layers are formed overtime from older rocks that have been broken apart by water or wind and often from chemical changes.
Science underpins technology. Technology underpins science. Science is discipline, technology is a tool.
