Question

multiple choice question
how does the shape of the red blood cell influence the cells function?
the biconcave shape increases the surface - area - to - volume ratio and facilitates gas exchange.
the biconcave shape decreases the surface - area - to - volume ratio and facilitates gas exchange.
the biconcave shape and multi - lobed nucleus facilitate gas exchange.

Explanation:

Red - blood cells are biconcave in shape. This shape increases the surface - area - to - volume ratio, which allows for more efficient gas exchange (oxygen uptake and carbon - dioxide release). Red - blood cells do not have a multi - lobed nucleus.

Answer:

The biconcave shape increases the surface - area - to - volume ratio and facilitates gas exchange.
