What is the purpose of the chemical messengers that pass between cells? Check ALL that apply. a To keep the rate of cell division equal with the rate of cell death.

b To help cells reproduce at a rapid rate.

c To inhibit cell death so that fewer new cells are needed.

d To help regulate the rate and timing of cell division.

B and D seem most credible although I am not 100%

Hope this helped.

a- all cells come from pre-existing cells

unicellular organisms, like bacteria, are able to perform all life functions within one single cell. multicellular organisms need many different types of cells to carry out the same life processes. each of these special types of cells has a different structure that it perform a specific function.
