thrombocytes - Correct Answers -(platelets) assist in clotting of the blood
anemia - Correct Answers -a lack of red blood cells in the body
tRNA - Correct Answers -bring the amino acids to the ribosomes for protein synthesis
erythrocytes - Correct Answers -(red blood cells) carry oxygen
plasma - Correct Answers -fluid portion of the blood that contains water, sugars, lipids,
wastes, and other components
amino acids - Correct Answers -building blocks of proteins
how is sickle cell passed down? - Correct Answers -autosomal recessive pattern (both
parents must contribute a copy)
