Along with sensory receptors, transport information to the integrating center.
a)effectors
b)signal pathways
c)sensory organs

The right answer is sensory organs.

An organ is called "sensory" when its action results in a sensory perception. In humans, the eyes, nose, tongue, ears, and skin are the sensory organs of the body. They allow an individual to perceive one of the five senses: sight, smell, taste, hearing, and touch. For this, these specific organs transmit information to the brain in the form of electrical pulses. In cats, the vibrios are the main sensory organ while the sensilla provide this function in arthropods.

mitosis is the process of dividing the cell,it has 4 parts interphase,anaphase,metaphase,and telophase.

lastly there's cytokines,that's when the cell divides into 2 daughter cells
