A process by which large particles may be taken into the cell for food, protection of the body, or disposing of old or dead cells is called phagocytosis

TRUE

The orderly sequence of the phases of mitosis is prophase, metaphase, anaphase, and telephase

TRUE

Telomeres are the region of chromosomes that code for the protien ubiquitin

FALSE

what happens during generation of a membrane potential

Both potassium and sodium ions leak through the cell membrane due to diffusion
