Answer 1

Answer:

red blood cells

Explanation:

The absence of a nucleus is an adaptation of the red blood cell for its role. It allows the red blood cell to contain more hemoglobin and, therefore, carry more oxygen molecules. It also allows the cell to have its distinctive bi-concave shape which aids diffusion.

Answer 2

Answer:

Red blood cells

Explanation:

Red blood cells are the set of living cells in which the nucleus is absent. This takes place so that more oxygen can be transported via these cells.

(Red blood cells contain haemoglobin for the same)

Due to the lack of a nucleus, they have a bi-concave shape.
