In the simulation, you will observe onion cells, red blood cells, and human bone cells under a microscope. Write down your predictions of the similarities and differences you will see when you look at these different types of cells. Please help I will give Branliest!​

Similarities  

All three cells will contain cytoplasm All three cells will have a cell membrane

Differences  

Only the onion cell will contain chloroplast The onion and human blood cells will contain a nucleus, but the red blood cell will not. Only the onion cell will have a large central vacuole Only the onion cell will contain a cell wall The red blood cell will have a disc shape while the onion cell will have a rigid shape and the bone cell has an irregular shape.

Ithink option a is correct because you cannot donate a different blood group than yours because it won't match.option a says betsy can donate to mark. they have the same blood group so donation can happen.
