What is the difference between parts B and C in malia's diagram?
(a) Part B is responsible for giving the cell structure and support and part C allows nutrients and waste to enter and leave the cell
(b)Part B is responsible for for letting nutrients and waste pass through the cell and part C holds all of the organelles in place
(c) both parts B and C are responsible for producing food for the cell
(d) there is no difference between B and C, their combined purposes to hold the cell together
The Amoeba, the paramecium, and the euglena ( These are unicellular Protozoans) produce electrical impulses that travel along their cell membrane. This is possible because they are specialized to use properties exhibited by all cells. These properties include ... A) Separation of the fluid environments inside and outside the cell B) Active transport of Na+ out of and K+ into the cell. C) Portal proteins that allow diffusion of Na+ and K+ back in to the cell D) Maintaining unequal Na+ and K+ concentrations on the two sides of the membrane. E) All of these are true
