Ahigh birth to death ratio leads to smaller populations

A high birth to death ratio leads to smaller populations.

This is false.                                                          

A high birth to death ratio means, that there are more births than deaths in a particular area. People are born at a higher rate than they die or the death rate is lower than the birth rate. This will lead to an increase in population.

what statement best describes the difference between the sympathetic and parasympathetic nervous systems?
