a.1 Eukaryotic Cell vs Prokaryotic Cell All cells can be classfied into prokaryotes and eukaryotes. Prokaryotes were the only form of life on Earth for millions of years until more complicated eukaryotic cells came into being through the process of evolution. Comparison chart All attributes Differences Similarities | Eukaryotic Cell | Prokaryotic Cell | Nucleus: | Present | Absent | Number of chromosomes: | More than one | One--but not true chromosome: Plasmids | Cell Type: | Multicellular

Sickle-Cell Anemia is a genetic blood disorder caused by the presence of an abnormal form of hemoglobin. These hemoglobin molecules tend to aggregate after unloading oxygen forming long‚ rod-like structures that force the red cells to assume a sickle shape. Unlike normal red cells‚ which are usually smooth and malleable‚ the sickle red cells cannot squeeze through small blood vessels. When the sickle cells block small blood vessels‚ the organs are deprived of blood and oxygen. This leads to periodic
