The altered protein affected the function of the cell membrane. The cell membrane which contain a bilayer control the movement of substance in and out of the cell and organelles. Due to this it is selective permeable to ion and organic molecules.
I'm pretty sure it's primary growth. I might not have studied this type of biology yet, but secondary growth would definitely not be the answer.<span />
They would kill the rest of the cells
because it is a new virus that us humans have not experienced and we are still learning about it
I don't know what your question is right here..? But cell division is when one cell copies DNA to make an exact copy to which the cell splits resulting in two daughter cells
