1.	Which one of the following human cells lacks a nucleus?(a) Neutrophil(b) Neuron(c) Mature erythrocyte(d) Keratinocyte
Answer» Answer is : (c) Mature erythrocyte Mature human erythrocytes (Red blood cells) lack a nucleus. The absence of a nucleus is an adaptation of the red blood cell for its role. It allows the RBC to contain more haemoglobin and therefore carry more oxygen molecules. It also allows the cell to have its distinctive biconcave shape which aids diffusion.
