Question

select all that apply
identify two functions that red blood cells are unable to perform because they lack organelles and nuclei.
cell division
transport of materials across the cell membrane
produce atp for cellular metabolism
protein synthesis

Explanation:

Cell division requires a nucleus for DNA replication and segregation. Protein synthesis needs ribosomes (an organelle) and the nucleus for mRNA production. Red - blood cells lack organelles and nuclei, so they can't perform these functions. Transport of materials across the cell membrane can occur via membrane - bound proteins and diffusion, and red - blood cells can still produce ATP anaerobically without a nucleus or most organelles.

Answer:

Cell division, Protein synthesis
