The right option is; it interprets signals from the external environment
The peripheral nervous system (PNS) is made up of all parts of the nervous system, except the brain and spinal cord (parts of the central nervous system). The peripheral nervous system functions as a channel through which neural signals are transferred from and to the central nervous system. Two types of neurons (sensory and motor neurons) functions in the PNS. The motor neurons transfer neural signals from the central nervous system directly to various muscles, glands, and organs (effectors) throughout the body.
The options attached to the question above are given below:
A. All living and nonliving things consist of one or more cells.
B. Cells and living organisms are spontaneously created.
C. Cells are the most complex unit of structure and function in living things.
D. A cell is the basic unit of structure and function of all organisms
ANSWER
The correct option is D.
The cell theory is one of the major theories in biology and it states the facts about living cells. The theory states that, the cell is the most basic unit of all organisms and all living organisms are made up of one or more cells. The organisms that are made up of only one cell are described as unicellular while those that possess many cells are described as multi cellular. The theory also states that all cells come from pre-existing cells.
I think its a density dependent limited factor
The answer could possibly be natural selection or survival of the fittest
