Individuals with the inherited disorder called [...]-cell anemia have red blood cells with a sickle shape that causes them to get stuck in small blood vessels. | Individuals with the inherited disorder called sickle-cell anemia have red blood cells with a sickle shape that causes them to get stuck in small blood vessels. |
Sickle-shaped blood cells are caused by a change in just [...] of the amino acids in the hemoglobin molecule. | Sickle-shaped blood cells are caused by a change in just one of the amino acids in the hemoglobin molecule. (it should be glutamic acid, but in sickle cells, it's usually valine) |
A sickle is a harvesting tool. It's basically a crescent-shaped knife used to cut bunches of grain or other plant crops. The sickle and star were symbols on the flag of the [...]. | A sickle is a harvesting tool. It's basically a crescent-shaped knife used to cut bunches of grain or other plant crops. The sickle and star were symbols on the flag of the Soviet Union. |
