Pregunta 73

Which shape adaptation gives a mature mammalian red blood cell a large surface-area-to-volume ratio?

  1. A solid spherical form
  2. A biconcave disc formRespuesta correcta
  3. A long branched form
  4. A rigid rectangular form

Explicación

A biconcave disc is indented on both faces, increasing surface area relative to the cell's volume and aiding exchange. A solid sphere has less surface area for the same volume, so it would not provide the stated advantage.
